Background: Mitral valve apparatus is complex and involves the mitral annulus, the leaflets, the chordae tendinae, the papillary muscles as well as the left atrial and ventricular myocardium. Secondary mitral regurgitation is consequence of regional or global left ventricle remodeling due to an acute myocardial infarction (75% of cases) or idiopathic dilated cardiomyopathy (25% of cases). It is associated with an increase in mortality and poor outcome. There is a potential survival benefit deriving from the reduction in the degree of severity of mitral regurgitation. So the correction of the valve defect can change the clinical course and prognosis of the patient. The rationale for mitral valve treatment depends on the mitral regurgitation mechanism. Therefore, it is essential to identify and understand the pathophysiology of the mitral valve regurgitation. Aim of the study: The aim of this review is to describe the crucial role of transthoracic and trans-esophageal echocardiography, in particular with 3D echocardiography, for the assessment of the severity of secondary mitral regurgitation, anatomy and hemodynamic changes in the left ventricle. Moreover, the concept that the mitral valve has no organic lesions has been abandoned. The echocardiography must allow a complete anatomical and functional evaluation of each component of the mitral valve complex, also useful to the surgeon in choosing the best surgical approach to repair the valve. Conclusions: Echocardiography is the first-line imaging modality for a better selection of patients, according to geometrical modifications of mitral apparatus and left ventricle viability, especially in preoperative phase.

The chordae tendinae connect the papillary muscles to the mitral valve. While the first-order chordae serve to secure the leaflets to maintain valve closure and prevent mitral valve prolapse, the second-order chordae are believed that they play a role in maintaining normal LV size and geometry. The papillary muscles, from where the chordae tendinae originate, function as shock absorbers that compensate for the geometric changes of the left ventricular wall. The second-order chordae connect the PMs to both trigons under tension. The tension distributed towards the second-order chordae has been demonstrate to be more than three-fold that in the first-order counterpart. Cutting the second-order chordae puts all the tension on the first-order chordae, that can go closer to their rupture point. However, it has been experimentally demonstrated that the tension where the first-order chordae break is 6.8 N, by far higher than the maximal tension reached, that is 0.4 N. Even if the clinical reports have been favorable, the importance of cutting the second-order chordae to recover curvature of the anterior leaflet and increasing the coaptation length between the mitral leaflet has been slowly absorbed by the surgical world. Nevertheless, there are progressive demonstrations that chordal tethering affects the anterior leaflet not only in secondary, but also in primary mitral regurgitation, having a not negligeable role in the long-term outcome of mitral repair.

The decision to treat moderate ischemic mitral regurgitation (IMR) at the time of coronary artery bypass surgery (CABG) remains controversial. We previously conducted a prospective randomized trial that showed a benefit of adding restricted annuloplasty to bypass surgery (CABG-Ring group) in terms of IMR grade, New York Heart Association classification, and left ventricle reverse remodeling. Here, we present the long-term (10 years) follow-up data from this randomized trial.The original trial arms accounted for 54 patients in the CABG-alone and 48 in the CABG-Ring group; patients were re-contacted for follow-up to obtain relevant clinical and echocardiographic information.The mean follow-up was 160.4 ± 45.5 months. Survival probabilities in the CABG-alone and CABG-Ring groups were 96% vs 93% at 3 years, 85% vs 89% at 6 years, 79% vs 85% at 9 years, 77% vs 83% at 12 years, and 72% vs 80% at 15 years, respectively (P = .18) Freedom from at least moderate IMR or reintervention at last follow-up was also higher in the CABG-Ring group (P.001). Compared with the CABG-alone group, the CABG-Ring group had a higher degree of left ventricular reverse remodeling (54.7 ± 6.9 mm vs 51.6 ± 6 mm, respectively; P = .03), lower New York Heart Association class (P.001), and a lower rate of rehospitalization (P = .002).Long-term follow-up data from our randomized trial further support the utility of performing restricted annuloplasty at the time of CABG to prevent further progression of IMR, mitral reintervention, and left ventricle remodeling. Untreated IMR was associated with significantly higher New York Heart Association class and rehospitalization.

Background: Recent data suggested that transcatheter aortic valve replacement (TAVR) may be indicated also for low-risk patients. However, robust evidence is still lacking, particularly regarding valve performance at follow-up that confers a limitation to its use in young patients. Moreover, a literature gap exists in terms of 'real-world' data analysis. The aim of this study is to compare the cost-effectiveness of sutureless aortic valve replacement (SuAVR) versus transfemoral TAVR.Methods: Prospectively collected data were retrieved from a centralized database of nine cardiac surgery centers between 2010 and 2018. Follow-up was completed in June 2019. A propensity score matching (PSM) analysis was performed.Results: Patients in the TAVR group (n = 1002) were older and with more comorbidities than SuAVR pa-tients (n = 443). The PSM analysis generated 172 pairs. No differences were recorded between groups in 30-day mortality [SuAVR vs TAVR: n = 7 (4%) vs n = 5 (2.9%); p = 0.7] and need for pacemaker implant [n = 10 (5.8%) vs n = 20 (11.6%); p = 0.1], but costs were lower in the SuAVR group (20486.6 +/- 4188 euro vs 24181.5 +/- 3632 euro ; p < 0.01). Mean follow-up was 1304 +/- 660 days. SuAVR patients had a significantly higher probability of survival than TAVR patients (no. of fatal events: 22 vs 74; p < 0.014). Median follow-up was 2231 days and 2394 days in the SuAVR and TAVR group, respectively.Conclusion: The treatment of aortic valve stenosis with surgical sutureless or transcatheter prostheses is safe and effective. By comparing the two approaches, patients who can undergo surgery after heart team evaluation show longer lasting results and a more favorable cost ratio. (C) 2021 Japanese College of Cardiology.

Purpose The aim of our study was to evaluate the prevalence of early complications after Transcatheter Aortic Valve Implantation (TAVI) and their correlation with the Calcium Score (CS) of the aortic valve, aorta and ilio-femoral arteries derived from pre-procedural computed tomography (CT). Materials and methods We retrospectively reviewed 226 patients (100 males, mean age 79.4 ± 6.7 years) undergoing 64-slice CT for pre-TAVI evaluation from January 2018 to April 2021. The population was divided into CS quartiles. Results Overall, 173 patients underwent TAVI procedure, of whom 61% presented paravalvular leak after the procedure, 28% presented bleeding or vascular complications, 25% presented atrioventricular block, and 8% developed acute kidney injury. The prevalence of paravalvular leak and vascular complications was higher in the upper CS quartiles for aortic valve and ilio-femoral arteries. Conclusions Aortic valve and vascular CS could help to predict post-TAVI early complications.

The long-term outcome of patients undergoing mitral valve repair (MVr) is based on what happens during the more or less 60 min of aortic cross-clamping necessary to transform a leaking valve into a well-functioning one. As a consequence, the experience of the surgeon performing the procedure is the only determinant of the success rate that deserves to be taken into account. It is clear from the literature that the number of cases/year is inversely related to the number of early and late deaths, repair failures, and reoperations. However, there is no agreement on the minimum caseload/year that represents the threshold to identify surgeons that can perform or not MVr. This problem then cannot be regulated by specific guidelines of Scientific Societies, but only by the ethical perception, we have of our profession.

Background. The effect of metabolic syndrome (MetS), defined as insulin resistance along with two or more of: obesity, atherogenic dyslipidaemia and elevated blood pressure, on post-operative complications after isolated heart valve intervention remains controversial. We hypothesized that MetS may negatively influence the post-operative course in these patients. Methods. Patients from 10 cardiac units who underwent isolated valve intervention (mitral ± tricuspid repair/replacement (MVS) or aortic valve replacement (SAVR), or transcatheter aortic valve replacement (TAVR) were included. MetS was defined according to the WHO criteria. Primary outcome was in-hospital mortality and overall post-operative length of stay. Relevant post-operative complications were also recorded. Results. From 2010 to 2019, 17283 patients underwent valve intervention. The MVS, SVAR and TAVR accounted for the 39.4%, 48.2% and 12.3% respectively of the whole. MetS compared to no-MetS was associated to higher mortality in the MVS group (6.5% vs. 2%, pConclusion. MetS was associated to more post-operative complications, with higher mortality in the MVS group. In the TAVR cohort, post-operative complications and mortality rate did not differ between patients with and without MetS, however length of stay was longer in the MetS group.

Heart failure and atrial fibrillation are often associated. Both conditions share pathophysiology and risk factor; as an example, atrial fibrillation may be regarded as either the ‘cause’ or the ‘consequence’ of heart failure. If coexistent, they are associated to very poor outcome. With this in mind, finding effective therapy for patients presenting with both heart failure and atrial fibrillation remains of paramount importance. There are also little evidence of the role and benefit of surgical atrial fibrillation ablation concomitant to heart surgery (i.e., coronary or valve surgery).

OBJECTIVES Sutureless aortic valve prostheses have been introduced to facilitate the implant process, speed up the operating time and improve haemodynamic performance. The goal of this study was to assess the potential advantages of using sutureless prostheses during minimally invasive aortic valve replacement in a large multicentre population. METHODS From 2011 to 2019, a total of 3402 patients in 11 hospitals underwent isolated aortic valve replacement with minimal access approaches using a bioprosthesis. A total of 475 patients received sutureless valves; 2927 received standard valves. The primary outcome was the incidence of 30-day deaths. Secondary outcomes were the occurrence of major complications following procedures performed with sutureless or standard bioprostheses. Propensity matched comparisons was performed based on a multivariable logistic regression model. RESULTS The annual number of sutureless valve implants increased over the years. The matching procedure paired 430 sutureless with 860 standard aortic valve replacements. A total of 0.7% and 2.1% patients with sutureless and standard prostheses, respectively, died within 30 days (P = 0.076). Cross-clamp times [48 (40–62) vs 63 min (48–74); P = 0.001] and need for blood transfusions (27.4% vs 33.5%; P = 0.022) were lower in patients with sutureless valves. No difference in permanent pacemaker insertions was observed in the overall population (3.3% vs 4.4% in the standard and sutureless groups; P = 0.221) and in the matched groups (3.6% vs 4.7% in the standard and sutureless groups; P = 0.364). CONCLUSIONS The use of sutureless prostheses is advantageous and facilitates the adoption of a minimally invasive approach, reducing cardiac arrest time and the number of blood transfusions. No increased risk of permanent pacemaker insertion was observed.

Background: Studies reporting on the outcome of 90-year-old patients undergoing cardiac surgery are scant in literature; and currently, those regarding the implementation of trans-catheter techniques number even fewer. Methods: We compared patients aged >89 years operated on between 1998 and 2008 at 8 Italian cardiac surgery centers, with patients of the same age operated on between 2009 and 2021. All of the patients were operated on with “open” surgery, with the exclusion of percutaneous valve repair/implantation procedures. Results: The patients of the two groups (group 98-08—127 patients, and group 09-21—101 patients) had comparable preoperative risk factors in terms of the LogEuroSCORE (98-08: 21.3 ± 6.1 vs. 09-21: 20.9 ± 11.1, p = 0.12). There was a considerable difference in the type of surgery (isolated valve, isolated coronary, and combined surgery, 46.5, 38.5, and 15% vs. 52, 13, and 35% in 98-08 and 09-21, respectively, p = 0.01). Analogous operating durations were recorded (cross-clamp time: 98-08: 46 ± 28 min vs. 09-21: 51 ± 28 min, p = 0.06). The number of packed bypasses was lower in 09-21 (1.3 ± 0.6 vs. 2.4 ± 1.2, p = 0.001). In the postoperative period, there was a statistically significant difference in the 30-day survival in favor of the “more recent” patients (98-08: 17 deaths (13.4%) versus 09-21: 6(5.9%); p = 0.001), also confirmed in the subgroups (12.2% vs. 0% in isolated coronary surgery, p < 0.001; and 12.3% vs. 0% in isolated valve surgery, p < 0.001). Conclusions: Accurate pre-, intra-, and post-operative evaluation/management to reduce biological impacts facilitate significant improvements in the outcomes in nonagenarian patients when compared to the results recorded in previous years.

OBJECTIVES The need for concomitant tricuspid surgery in patients who need mitral valve surgery casts doubt on its feasibility via a minimally invasive approach. Our goal was to evaluate the short-term outcomes of patients undergoing concomitant mitral and tricuspid valve surgery either with a standard full sternotomy (full-MTS) or a minimally invasive approach (mini-MTS). METHODS The outcomes of patients who had combined mitral and tricuspid valve surgery in 11 centres were retrospectively evaluated. The primary outcome was the incidence of 30-day mortality. A propensity score matched cohort was selected to create 2 comparable groups stratified by surgery (valve replacement or repair). RESULTS During the study period, 1048 consecutive patients had combined mitral and tricuspid valve surgery (730 full-MTS, 318 mini-MTS). The matching procedure paired 192 full-MTS to 192 mini-MTS procedures. After matching, mini-MTS was associated with longer cardiopulmonary bypass [123 min, standard deviation (SD) 46, vs 102 min, SD 36, P = 0.001] and cross-clamping times (89 min, SD 34, vs 78 min, SD 29, P = 0.003). Although the hospital length of stay was shorter (8 days, interquartile range 7-12 vs 9 days, interquartile range 7–14, P = 0.034) with mini-MTS before matching, this difference disappeared after matching. No differences in other major complications or in 30-day mortality were observed: 48 deaths (4.6%), 36 of which (4.9%) occurred in patients who had a full-MTS and 12 (3.8%), in patients who had a mini-MTS (4.7% in both approaches paired by propensity). CONCLUSIONS The mini-MTS approach proved to be safe and effective in patients requiring concomitant mitral and tricuspid surgery. We could not demonstrate any difference in short-term outcomes between the 2 surgical approaches, indicating that there is not a preferred surgical approach.

The effect of hospital-associated SARS-CoV-2 infections in cardiac surgery patients remains poorly investigated, and current data are limited to small case series with conflicting results.A multicenter European collaboration was organized to analyze the outcomes of patients who tested positive with hospital-associated SARS-CoV-2 infection after cardiac surgery. The study investigators hypothesized that early infection could be associated with worse postoperative outcomes; hence 2 groups were considered: (1) an early hospital-associated SARS-CoV-2 infection group comprising patients who had a positive molecular test result ≤7 days after surgery, with or without symptoms; and (2) a late hospital-associated SARS-CoV-2 infection group comprising patients whose test positivity occurred7 days after surgery, with or without symptoms. The primary outcome was 30-day mortality. Secondary outcomes included all-cause mortality or morbidity at early follow-up and SARS-CoV-2-related hospital readmission.A total of 87 patients were included in the study. Of those, 30 were in the early group and 57 in the late group. Overall, 30-day mortality was 8%, and in-hospital mortality was 11.5%. The reintubation rate was 11.4%. Early infection was significantly associated with higher mortality (adjusted OR, 26.6; 95% CI, 2, 352.6; P.01) when compared with the late group. At 6-month follow-up, survival probability was also significantly higher in the late infection group: 91% (95% CI, 83%, 98%) vs 75% (95% CI, 61%, 93%) in the early infection group (P = .036). Two patients experienced COVID-19-related rehospitalization.In this multicenter analysis, hospital-associated SARS-CoV-2 infection resulted in higher than expected postoperative mortality after cardiac surgery, especially in the early infection group.

The natural history of secondary mitral regurgitation (MR) is unfavorable. Nevertheless, there are no evidence that its correction can improve the outcome. If from one side the original cause of secondary MR can be such to limit the possibilities of improvement, from the other side it is possible that the surgical technique widely applied to repair, restrictive mitral annuloplasty, is not adequate to correct the regurgitation. The addition of valvular and/or subvalvular techniques has been considered a possible technical solution. However, we do not know the prevalence of each technique, how many times mitral replacement is used to correct secondary MR. This aspect is of particular importance, as we know that a successful mitral repair causes a better left ventricular systolic remodeling than a unsuccessful repair or replacement. This study is a prospective, observational registry, conceived to understand what is done in the real world. Any surgeon will use the technique he thinks the most suitable for the patient. Every year, for 5 years, patients will have a clinical and echocardiographic follow-up, to evaluate the risk factors for a worse result (death, rehospitalization for heart failure, reoperation for MR return, moderate, or more MR return). This knowledge will give us the possibility to understand which is the technique, or the strategy, more efficient to treat this disease and the real efficacy of the surgical treatment.

Mitral valve surgery (MVS) is evolving. Compared to standard sternotomy (S-MVS), minimally invasive method (Mini-MVS) has been increasingly adopted in the last years with encouraging results for both repairs and replacements. We evaluated trends of surgical approaches and operative outcomes in a multicenter study involving 10 cardiac surgical centers in Italy.Patients who received isolated mitral valve surgery, including only a concomitant tricuspid valve repair, from January 2011 up to December 2017. Minimally invasive approach (right anterior mini-thoracotomy) and standard sternotomy was performed in 2602 and 1947 patients, respectively. Stratifying by surgery, 1493 patients per group were paired using a propensity matching procedure.The minimally invasive approach has been progressively more frequent over the years (from 27.5% in 2011 to 71.7% in 2017). Compared to S-MVS, Mini-MVS patients were younger with less preoperative comorbidities and less frequently operated for valve replacement or in association with tricuspid repair. The 30-day mortality was lower in the Mini-MVS (overall 1.2% vs 2.7%; p 0.001) as well as the incidence of most postoperative complications. Subjects paired by propensity score had similar 30-day mortality (1.9% vs 1.8%, p = 0.786) but lower blood transfusion and permanent pace-maker insertion. Cardiopulmonary bypass and cross-clamp time, initially longer in the Mini-MVS patients, became shorter in recent years for the minimally invasive approach.In a large multi-institutional recent cohort, minimally invasive mitral valve surgery has drastically increased being the preferred technique and appears to be safe with procedural duration shorter than the beginning.

There is high demand for minimally invasive mitral valve repair; however, it is unclear whether the minimally invasive approach provides the same performance as conventional sternotomy in a context of complex mitral valve disease. Here, we compared outcomes of minimally invasive and sternotomy procedures for bileaflet and Barlow's mitral valve disease.We performed a pooled meta-analysis of studies reporting early and late follow-up of mitral valve repair for complex mitral valve regurgitation. The primary outcome was moderate mitral valve regurgitation recurrence and need for reoperation. Secondary outcomes included operation time, reopening for bleeding, associated tricuspid procedures, failed repair, and inhospital mortality. Incidence rates were calculated for long-term follow-up. Effect estimates were calculated as incidence rates with 95% confidence intervals. When Kaplan-Meier curves were available, event rates were estimated from the curves with Plot Digitizer software; otherwise, reported event rates were used to calculate incidence rates.Eighteen studies including 1905 patients (654 minimally invasive and 1251 sternotomy) with a mean follow-up of 51.6 months (range, 14 to 138) were meta-analyzed with a random model. There were no significant between-group differences in moderate mitral valve regurgitation recurrence and reoperation (minimally invasive vs sternotomy, 1.7% [95% confidence interval, 1.0% to 2.9%] vs 1.3% [95% confidence interval, 0.9% to 1.8%], P = .22). Patients in the minimally invasive group were exposed to significantly longer cross-clamp and cardiopulmonary bypass times (P.01); however, there were no additional between-group differences in secondary outcomes.This meta-analysis has demonstrated that minimally invasive and sternotomy approaches produce comparable results for complex mitral valve repair.

Objective The impact of coronavirus disease 2019 (COVID-19) on the postoperative course of patients after cardiac surgery is unknown. We experienced a major severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) outbreak in our cardiac surgery unit, with several patients who tested positive early after surgery. Here we describe the characteristics, postoperative course, and laboratory findings of these patients, along with the fate of the health care workers. We also discuss how we reorganize and reallocate hospital resources to resume the surgical activity without further positive patients. Methods After diagnosis of the first symptomatic patient, surgery was suspended. Nasopharyngeal swabs were performed in all patients and health care workers. Patients who were positive for SARS-CoV-2 were isolated and monitored throughout the in-hospital stay and followed up after discharged until death or clinical recovery. Results Twenty patients were found to be positive for SARS-CoV-2 sometime after cardiac surgery (mean age 69 ± 10.4 years; median European System for Cardiac Operative Risk Evaluation II score 3 [interquartile range, 5.1]); the median time from surgery to diagnosis was 15 days (interquartile range, 11). Among the patients, 18 had undergone cardiac surgery and 2 of them transcatheter aortic valve replacement. Overall mortality was 15%. Specific COVID-19–related symptoms were identified in 7 patients (35%). Among the 12 health care workers infected, 1 developed a bilateral mild-grade interstitial pneumonia. Conclusions COVID-19 infection after cardiac surgery, regardless the time of the onset, is a serious condition. The systemic inflammatory state that follows extracorporeal circulation may mask the typical COVID-19 laboratory findings, making the diagnosis more difficult. A strict reorganization of the hospital resources is necessary to safely resume the cardiac surgical activity.

There are no solid evidence from literature that compare Cox-Maze with pulmonary vein isolation technique for atrial fibrillation in the context of concomitant mitral valve surgery. While the first is perhaps more effective and linked to higher freedom form atrial fibrillation, it is more invasive compared to the pulmonary isolation.

Background More than 1.6 million Americans have at least moderate to severe valvular tricuspid regurgitation, yet fewer than 8000 tricuspid valve operations are performed annually in the USA. The undertreatment for isolated tricuspid regurgitation might be related to the fact that in the past years no clear guidelines on 'how' and 'when' to treat tricuspid regurgitation were issued. Aims Sarris-Michopoulos and colleagues carried out a meta-analysis with the aim to investigate the role of tricuspid valve repair versus tricuspid valve replacement in patients with isolated tricuspid valve regurgitation. Material and methods Outcomes of patients with first-time surgery for isolated tricuspid valve regurgitation without previous left-sided valve surgery were reviewed. Ten studies were included with a total of 1407 patients. Results Authors concluded that patients who underwent tricuspid valve repair showed less 30-days mortality than replacement along with a reduced need for post-operaitve permanent pacemaker implantation rate. Discussion Decision on whether to treat or not tricuspid valve is demanding, particularly in the context of the newest percutaneous technologies. Before intervention, careful evaluation of both tricuspid valve and right ventricle must be performed. Nevertheless, intervention, should not be deferred when clinically indicated. Conclusions The findings form this meta-analysis suggest that reparative surgery, perhaps in an early stage, may be beneficial in selected cohort of patients.

Patients with aortic stenosis (AS) and prior mediastinal radiotherapy (XRT) represent a challenging group ([1–3][1]). The detrimental effects due to the pressure overload associated with AS may be compounded by the presence of radiation heart disease. Echocardiographic speckle-tracking strain

OBJECTIVES Small aortic prosthetic valves have been associated with suboptimal performance due to patient–prosthesis mismatch (PPM). This meta-analysis compared the outcomes of patients with a small root who received tissue versus mechanical aortic valves. METHODS A systematic literature review identified 7 candidate studies; of these, 5 met the meta-analysis criteria. We analysed outcomes for a total of 680 patients (227 tissue valves and 453 mechanical valves) using random effects modelling. Each study was assessed for heterogeneity and quality. The primary end point was mortality at follow-up. Secondary end points included intraoperative and postoperative outcomes, the rate of PPM and left ventricle mass regression and major cardiac and prosthesis-related adverse events at follow-up. RESULTS There was no between-group difference in mortality at follow-up [incidence rate ratio 1, 95% confidence interval (CI) 0.50–2.01; P = 0.99]. The tissue group had a higher rate of PPM (odds ratio 17.19, 95% CI 8.6–25.78; P = 0.002) and significantly less reduction in ventricular mass (weighted mean difference 40.79, 95% CI 4.62–76.96; P = 0.02). There were no significant differences in the incidence of structural valve disease at follow-up compared to that in the mechanical valve group. There was also no between-group difference in aggregated adverse events at follow-up (P = 0.68). CONCLUSIONS Tissue and mechanical valves were associated with similar mortality rates; however, patients receiving tissue valves had a higher rate of PPM and significantly less left ventricle mass regression. These findings indicate that patients receiving small tissue valves may require closer clinical surveillance than those receiving mechanical valves.

An aortic aneurysm may cause loss of the sinotubular junction. Reduction in the diameter of the sinotubular junction may reestablish aortic valve competence in patients with an ascending aortic aneurysm and aortic valve regurgitation with normal aortic cusps. With this video tutorial we describe an alternative technique for replacing the ascending aorta with restoration of the sinotubular junction.

Background We sought to determine if a modified technique for ascending aorta replacement with sinotubular junction reduction and stabilization was safe. Methods This technique was performed by suspension of the three commissures, invagination of the aortic Dacron graft and advancing the graft into the ventricles. We included patients with dilatation of the ascending aorta, normal sinuses of Valsalva dimension (25 mm) and with various degree of aortic insufficiency (from grade 1 to 3). Results From April to October 2019, 20 patients were recruited from two centers; mean age was 66.9 ± 12.8 years, 13 were male; grade 1, 2 and 3 was present in 12, 2 and 6 patients, respectively. All patients underwent ascending aorta replacement with modified technique; an additional open subvalvular ring was used in 8 patients with aortic insufficiency ≥ 2; cusps repair was performed in 6 patients (5 plicating central stitches/1 shaving); concomitant coronary artery bypass grafting was performed in 10 patients. There was no 30-day mortality. One patient was re-explored for bleeding. All patients completed six-month follow-up; at the transthoracic echocardiography, there was no aortic insufficiency ≥ 1 except one patient with aortic insufficiency grade 1 who underwent ascending aorta replacement and subvalvular ring; no patients underwent reintervention. Conclusions This modified technique for ascending aorta replacement and sinotubular junction stabilization was safe. It could be associated with other aortic valve sparing techniques. However, such remodeling approach has to be validated in a larger cohort of patients with longer follow-up.

Patient selection is mandatory to successful mitral valve repair in functional mitral valve regurgitation. Preoperative echo evaluation is critical to better evaluate the anatomic modification of the mitral apparatus. In light of recent randomized trials, several patients could benefit from transcatheter mitral therapy. Mitral annuloplasty is not effective in all patients with functional mitral valve regurgitation; meanwhile, adding surgical techniques should be performed to improve the repair durability.

OBJECTIVES Female sex is an established risk factor for postoperative complications after heart surgery, but the influence of sex on outcomes after minimally invasive cardiac surgery (MICS) for valvular replacement/repair remains controversial. We examined whether the role of sex as a risk factor varies by surgical approach [MICS vs conventional sternotomy (ST)] and further assessed outcomes among female patients including in-hospital mortality and postoperative complications by surgical approach. METHODS We analysed data from a multicentre registry for patients who underwent isolated aortic valve and mitral surgery with MICS or ST. The primary outcome was in-hospital mortality. Propensity score matching was used to minimize between-group differences. RESULTS Among the 15 155 patients included in the study, 7674 underwent MICS (50.6%). Female sex was equally distributed in the MICS and ST groups (47.3% vs 47.6%, respectively). Risk for surgery was higher in the ST group than in the MICS group {EuroSCORE II: 4.0 [standard deviation (SD): 6.8] vs 3.7 [SD: 6.4]; P = 0.005}, including among female patients only [ST vs MICS 4.6 (SD: 6.9) vs 4.2 (SD: 6.3); P = 0.04]. Mortality did not significantly vary by procedure among women [MICS vs ST, 2.4% vs 2.8%; hazard ratio 1.09, 95% confidence interval 0.71–1.73; P (surgical approach × sex) = 0.51]. The results also did not vary after adjusting for confounders. CONCLUSIONS Female sex was associated with higher mortality in patients undergoing valve surgery, regardless of surgical approach. In female patients, MICS did not provide any benefits over ST in terms of in-hospital deaths or postoperative complications. Subject collection 117, 125.

Objective Cardiac tumors are rare conditions. The vast majority of them are benign yet they may lead to serious complications. Complete surgical resection is the gold standard treatment and should be performed as soon as the diagnosis is made. Median sternotomy (MS) is the standard approach and provides excellent early outcomes and durable results at follow-up. However, minimally invasive (MI) is gaining popularity and its role in the treatment of cardiac tumors needs further clarification. Methods A systematic literature review identified 12 candidate studies; of these, 11 met the meta-analysis criteria. We analyzed outcomes of 653 subjects (294 MI and 359 MS) with random effects modeling. Each study was assessed for heterogeneity. The primary endpoints were mortality at follow-up and tumor relapse. Secondary endpoints included relevant intraoperative and postoperative outcomes; tumor size was also considered. Results There were no significant between-group differences in terms of late mortality (incidence rate ratio [IRR]: MI vs. MS, 0.98 [95% confidence interval [CI]: 0.25-3.82], p = .98). Few relapses (IRR: 1.13; CI: 0.26-4.88; p = .87) and redo surgery (IRR: 1.92; 95% CI: 0.39-9.53; p = .42) were observed in both groups; MI approach resulted in prolonged operation time but that did not influence the clinical outcomes. Tumor size did not significantly differ between groups. Conclusion Both MI and MS are associated with excellent early and late outcomes with acceptable survival rate and low incidence of recurrences. This study confirms that cardiac tumor may be approached safely and radically with a MI approach.

OBJECTIVES We performed a literature meta-analysis to estimate the rate of pacemaker implantation after Perceval sutureless aortic valve replacement. METHODS Pertinent articles were identified from the PubMed, Google Scholar, Ovid MEDLINE and Ovid EMBASE databases. Eligible studies reported the de novo incidence of postoperative pacemaker implantation after Perceval valve surgery. Among 394 articles retrieved, 26 studies including 9492 patients met the inclusion criteria. RESULTS The pooled event rate for postoperative pacemaker implantation was 7% [95% confidence interval (CI) 6–9%]; however, significant heterogeneity was observed across studies. In a sub-analysis, there was no difference between the rates of pacemaker implantation calculated from multicentre and registry studies (8 studies, 6845 patients; 7%, 95% CI 5–10%) and single-centre studies (18 studies, 2647 patients; 7%, 95% CI 5–9%; P = 0.75). Implantation rates were similar in high-volume studies (16 studies, 9121 patients; 7%, 95% CI 5–8%) than in low-volume studies (10 studies, 371 patients; pooled rate: 7%, 95% CI 4–14%; P = 0.5). Postoperative pacemaker implantation rates tended to decrease over time. CONCLUSIONS With a pooled event rate of 7%, postoperative pacemaker implantation remains an important limitation of Perceval sutureless valve surgery, although we observed a degree of variability across included studies. The resultant findings provide a useful estimate for physicians and patients and can serve as a benchmark for future comparative studies. PROSPERO registration number CRD42020188397.

Tricuspid regurgitation (TR) is a frequent and complex problem, commonly combined with left-sided heart disease, such as mitral regurgitation. Significant TR is associated with increased mortality if left untreated or recurrent after therapy. Tricuspid regurgitation was historically often disregarded and remained undertreated. Surgery is currently the only Class I Guideline recommended therapy for TR, in the form of annuloplasty, leaflet repair, or valve replacement. As growing experience of transcatheter therapy in structural heart disease, many dedicated transcatheter tricuspid repair or replacement devices, which mimic well-established surgical techniques, are currently under development. Nevertheless, many aspects of TR are little understood, including the disease process, surgical or interventional risk stratification, and predictors of successful therapy. The optimal treatment timing and the choice of proper surgical or interventional technique for significant TR remain to be elucidated. In this context, we aim to highlight the current evidence, underline major controversial issues in this field and present a future roadmap for TR therapy.

The aim of this study was to compare minimally invasive surgery (MI) and median sternotomy (MS) in terms of post-procedure health-related quality of life (HRQoL) and functional outcome.We conducted a multicentre prospective cohort study that enrolled patients from January 2015 until February 2017. Combined cardiac procedures were performed with MS and isolated valve procedures with either MS or MI, depending on patient preference and surgeon experience. HRQoL was measured using the five-level version of the EQ-5D (EQ-5D-5L) and physical activity before and after surgery was evaluated using a wearable accelerometer. Activity patterns and intensity recorded by the accelerometer in each period were classified as "sedentary", "light physical activity", "moderate physical activity", and "vigorous physical activity" for each patient. We also conducted a sub-analysis of frail patients in each group, as identified by the Reported Edmonton Frail Scale (10 points). Patients were followed for 1 year.The study included 100 consecutive patients who underwent MI (n=50) or MS (n=50) during the study period. Patients in the MI group showed a faster recovery of physical activity in the immediate postoperative period and superior HRQoL in the first 3 months (both p0.001) versus the MS group. Differences between the MI and MS group were indistinguishable over a longer follow-up. A similar correlation was observed in the frailty subanalysis. Overall, the MS group had a higher cumulative incidence of events than the MI group (p0.001).Compared to conventional MS, MI was associated with better HRQoL and early functional outcome, even in frail patients.

Chronic secondary mitral valve regurgitation is associated with a poor prognosis. Yet, in contrast to primary mitral regurgitation, there is no clear evidence that a reduction in regurgitation improves survival. The limited availability of data regarding secondary mitral regurgitation has resulted in a low level of evidence for treatment recommendations. We evaluated the influence of minimally invasive mitral valve annuloplasty on survival, freedom from recurrent regurgitation, and other echocardiographic parameters in patients with "standalone" secondary mitral valve regurgitation.The analysis included patients with severe secondary mitral regurgitation, left ventricular function40%, and persistent symptoms, despite optimal medical therapy. We excluded patients who were eligible for coronary artery revascularisation or cardiac resynchronisation therapy (i.e., not standalone mitral regurgitation). After discharge, patients were scheduled for outpatient clinic follow-up at 1, 3, 6, and 12 months.From 2012 to 2018, 54 consecutive patients underwent minimally invasive mitral valve annuloplasty for severe standalone secondary mitral regurgitation. All patients were discharged with no or trivial residual regurgitation. The mean duration of follow-up was 33.5±16.8 months. Overall survival was 90% at 4 years postprocedure. Freedom from moderate regurgitation or reintervention was 89% at the 4-year follow-up. There was a low incidence of readmission for heart failure and patients showed consistent improvements in left ventricular function and symptoms.Mitral valve repair with reduction and stabilisation of the annulus may be beneficial for symptomatic patients with secondary stand-alone mitral regurgitation.

The severe acute respiratory syndrome coronavirus 2 (Sars-CoV-2) outbreak is a public health emergency affecting different regions around the world. The lungs are often damaged due to the presence of Sars-CoV-2 binding receptor ACE2 on epithelial alveolar cells. Severity of infection varies from complete absence of symptomatology to more aggressive symptoms, characterized by sudden acute respiratory distress syndrome (ARDS), multiorgan failure, and sepsis, requiring treatment in intensive care unit (ICU). It is not still clear why the immune system is not able to efficiently suppress viral replication in a small percentage of patients. It has been documented as pathological conditions affecting the cardiovascular system, strongly associated to atherosclerotic progression, such as heart failure (HF), coronary heart disease (CHD), hypertension (HTN) and diabetes mellitus (DM), could serve as predictive factors for severity and susceptibility during Sars-CoV-2 infection. Atherosclerotic progression, as a chronic inflammation process, is characterized by immune system dysregulation leading to pro-inflammatory patterns, including interleukin 6 (IL-6), tumor necrosis factor α (TNF-α), and IL-1β. Reviewing immune system and inflammation profiles in atherosclerosis and laboratory results reported in severe COVID-19 infections, we hypothesized a pathogenetic correlation. Atherosclerosis may be an ideal pathogenetic substrate for high viral replication ability, leading to adverse outcomes, as reported in patients with cardiovascular factors. The level of atherosclerotic progression may affect a different degree of severe infection; in a vicious circle, feeding itself, Sars-CoV-2 may exacerbate atherosclerotic evolution due to excessive and aberrant plasmatic concentration of cytokines.

Condensation and water loss from gas output of the cardiopulmonary bypass (CPB) oxygenator has been the study object of several research. However, little is known about the propagation of the condensation formed at the level of oxygenator and how potentially it can contaminate the surrounding environment. We aimed to document the moment of formation of the 'gas steam' derived from the CPB oxygenator during cardiac surgery with thermography imaging. Thermographic camera is a device that creates an image using infrared radiation, similar to a common camera that forms an image using visible light. The brightest (warmest) parts of the image are customarily colored white, the intermediate temperatures reds and yellows, and the dimmest (coolest) parts black. Thermal image captures the condensation phenomenon around the oxygenator perimeter with the same color/temperature code (yellow) of gas outlet. The use of aspiration at the level of the gas outlet could also favor the elimination of the condensation, improve gas exchanges, and potentially reduce the spread of hazardous substances in the operating room.

Mitral regurgitation (MR) is increasingly prevalent in western countries despite reduced incidence of rheumatic disease (1,2). MR results from several heterogeneous conditions, including disorders of the valve leaflets, mitral annulus, chordae tendineae, papillary muscles and left ventricle (LV). MR causes are roughly classified as primary (i.e. organic/structural) or secondary (i.e. functional/non-structural) (3).

OBJECTIVES Surgical aortic valve replacement (AVR) can be performed via a full sternotomy or a minimal access approach (mini-AVR). Despite long-term experience with the procedure, mini-AVR is not routinely adopted. Our goal was to compare contemporary outcomes of mini-AVR and conventional AVR in a large multi-institutional national cohort. METHODS A total of 5801 patients from 10 different centres who had a mini-AVR (2851) or AVR (2950) from 2011 to 2017 were evaluated retrospectively. Standard aortic prostheses were used in all cases. The use of the minimally invasive approach has increased over the years. The primary outcome is the incidence of 30-day deaths following mini-AVR and AVR. Secondary outcomes are the occurrence of major complications following both procedures. Propensity-matched comparisons were performed based on the multivariable logistic regression model. RESULTS In the overall population patients who had AVR had an increased surgical risk based on the EuroSCORE, and the 30-day mortality rate was higher (1.5% and 2.3% in mini-AVR and AVR, respectively; P = 0.048). Propensity scores identified 2257 patients per group with similar baseline profiles. In the matched groups, patients who had mini-AVR, despite longer cardiopulmonary bypass (81 ± 32 vs 76 ± 28 min; P = 0.004) and cross-clamp (64 ± 24 vs 59 ± 21 min; P ≤ 0.001) times, had lower 30-day mortality rates (1.2% vs 2.0%; P = 0.036), reduced low cardiac output (0.8% vs 1.4%; P = 0.046) and reduced postoperative length of stay (9 ± 8 vs 10 ± 7 days; P = 0.004). Blood transfusions (36.4% vs 30.8%; P ≤ 0.001) and atrial fibrillation (26.0% vs 21.5%, P ≤ 0.001) were higher in patients who had the mini-AVR. CONCLUSIONS In a large multi-institutional recent cohort, minimal access approach aortic valve replacement is associated with reduced 30-day mortality rates and shorter postoperative lengths of stay compared to standard sternotomy. A prospective randomized trial is needed to overcome the possible biases of a retrospective study.

Objectives Treatment of aortic valve stenosis is evolving, indications for transcatheter approach (TAVI) have increased but also surgical valve replacement has changed with the use of minimally invasive approaches. Comparisons between TAVI and surgery have rarely been done with minimally invasive techniques (mini-SAVR) in the surgical arm. Aim of the present study is to compare mini-SAVR and TAVI in a multicenter recent cohort. Methods Evaluated were 2904 patients undergone mini-SAVR (2407) or TAVI (497) in 10 different centers in the period 2011–2016. The Heart Team approved treatment for complex cases. The primary outcome is the incidence of 30-day mortality following mini-SAVR and TAVI. Secondary outcomes are the occurrence of major complications following both procedures. Propensity matched comparisons was performed based on multivariable logistic regression model. Results In the overall population TAVI patients had increased surgical risk (median EuroSCORE II 3.3% vs. 1.7%, p ≤ 0.001) and 30-day mortality was higher (1.5% and 2.8% in mini-SAVR and TAVI respectively, p = 0.048). Propensity score identified 386 patients per group with similar baseline profile (median EuroSCORE II ~3.0%). There was no difference in 30-day mortality (3.4% in mini-SAVR and 2.3% in TAVI; p = 0.396) and stroke, surgical patients had more blood transfusion, kidney dysfunction and required longer ICU and hospital length of stay while TAVI patients had more permanent pace maker insertion. Conclusions Mini-SAVR and TAVI are both safe and effective to treat aortic stenosis in elderly patients with comorbidities. A joint evaluation by the heart-team is essential to direct patients to the proper approach., Highlights • A comparison between TAVI and minimally invasive techniques has rarely been done • In a propensity-matched comparison from 10 different hospitals, TAVI and mini-SAVR provided optimal short-term outcome. • 30-day mortality was 3.4% in mini-SAVR and 2.3% in TAVI (p = 0.396) • Mini-SAVR and TAVI are both safe and effective to treat aortic stenosis in elderly patients with comorbidities.

We present a case of redo mitral valve surgery after failed repair that consisted of implantation of a complete ring over an open band implanted several years prior. The patient presented with severe central mitral regurgitation. During surgical intervention, the open band was identified consolidated with the native annulus. We elected not to remove the posterior annulus given the presence of calcification. Instead, a new complete ring was secured with single sutures posteriorly over the band and anterior to the native annulus. This approach was safe, fast, and achieved a significant reduction in annulus circumference with no residual mitral regurgitation.

Background The effects of surgical aortic valve replacement versus transcatheter aortic valve replacement on endothelial function are unknown. We investigated the effects of surgical and transcatheter aortic valve replacement on early and 90-day endothelial function measured by brachial flow mediated dilation and apoptotic rate in the human umbilical vein endothelial cells in patients with significant aortic stenosis, intermediate risk of surgery, and no coronary artery disease. Methods We conducted a prospective observational case control single-blind study at a single tertiary center. Endothelial function was measured at baseline, early post-procedure (4 days), and follow-up (90 days). A blood pressure cuff was used to elicit reactive hyperemia for measuring brachial wall shear stress and flow mediated dilation. The apoptosis rate was observed in the human umbilical vein endothelial cells after 48-h incubation with 20% serum from patients. The rate of apoptosis was assessed by determining the number of annexin V and propidium iodide positive cells by flow cytometry. Results Early post-procedure flow dilation was significant lower in the surgical group (p

Venodilation occurs shortly after the institution of cardiopulmonary bypass (CPB), necessitating fluid or vasoconstrictor administration to maintain adequate oxygen delivery. The vasoconstrictor effects of dopamine are not well studied in this context. Therefore, we conducted a single-center, double-blind case-control study to determine the role and utility of dopamine as a vasoconstrictor during CPB. The study included 60 adults who were scheduled for isolated elective/urgent coronary artery bypass grafting. Patients in group A (n = 30) received a dopamine bolus (2 mg) 20 min after cross-clamping, whereas patients in group B (n = 30) did not receive any intervention at a specific time point. Both groups received standard care as needed (fluid replacement or norepinephrine bolus). Venous return was measured directly in the reservoir and indirectly by Doppler measurement at the level of the inferior vena cava with transesophageal echocardiography. Both open and closed circuits were used for CPB. A single dopamine bolus (2 mg) increased volume in the venous reservoir in group A. Group A patients also received significantly fewer units of red blood cells in the intensive care unit (ICU) than did patients in group B. There were no significant between-group differences in postoperative bleeding, mechanical ventilation, or length of stay in the ICU. These findings suggest that use of a dopamine bolus can increase venous return and reduce the need for fluid replacement during and after CPB in patients undergoing coronary artery bypass grafting.

Background Minimal access valve surgery, both mitral and aortic, may be related to improvement in specific post-operative outcomes, therefore may be beneficial for the subgroup of the elderly referred for valve surgery. Methods A systematic literature review identified several different studies, of which 6 fulfilled criteria for meta-analysis. Outcomes for a total of 1347 patients (675 conventional standard sternotomy and 672 minimally invasive valve surgery) were assessed with a meta-analysis using random effects modeling. Heterogeneity, subgroup analysis with quality scoring were also assessed. The primary endpoint was early mortality. Secondary endpoints included intra and post-operative outcomes. Results In the context of elderly patients, minimal access valve surgery conferred comparable early mortality to standard sternotomy (odd ratio (OR) 0.79, CI [0.40,1.56], p = 0.50) with no heterogeneity (p = 0.13); it was also associated with reduced mechanical intubation time (OR 0.48, CI [0.30,0.78], p = 0.003) and reduced post-operative length of stay (weighted mean difference (WMD) −2.91, CI [−3.09, −2.74] p

Background. Minimally invasive valve surgery is related to certain better postoperative outcomes. We aimed to assess the role of minimally invasive mitral valve surgery in high-risk patients. Methods. A systematic literature review identified eight studies of which seven fulfilled criteria for metaanalysis. Outcomes for a total of 1,254 patients (731 were conventional standard sternotomy and 523 were minimally invasive mitral valve surgery) were submitted to meta-analysis using random effects modeling. Heterogeneity and subgroup analysis with quality scoring were assessed. The primary end point was early mortality. Secondary end points were intraoperative and postoperative outcomes and long-term follow-up. Results. Minimally invasive mitral valve surgery conferred comparable early mortality to standard sternotomy (p [ 0.19); it was also associated with a lower number of units of blood transfused (weighted mean difference, L1.93; 95% confidence interval [CI], L3.04 to L0.82; p [ 0.0006) and atrial fibrillation rate (odds ratio, 0.49; 95% CI, 0.32 to 0.74; p [ 0.0007); however, cardiopulmonary bypass time was longer (weighted mean difference, 20.88; 95% CI, L1.90 to 43.65; p [ 0.07). There was no difference in terms of valve repair rate (odds ratio, 1.51; 95% CI, 0.89 to 2.54; p [ 0.12), and the incidence of stroke was significantly lower in the high-quality analysis with no heterogeneity (odds ratio, 0.35; 95% CI, 0.15 to 0.82; p [ 0.02; c 2 , 1.67; I 2 ,0 %;p [ 0.43). Conclusions. Minimally invasive mitral valve surgery is a safe and comparable alternative to standard sternotomy in patients at high risk, with similar early mortality and repair rate and better postoperative outcomes, although a longer cardiopulmonary bypass time is required.

Application of statistical process charts has led to consistent quality production improvement in the industrial sector. Aim of this simulation study is to assess if the use of exponentially weighted moving average chart with control limits (CL) could help to identify mortality trends in a cardiac surgery scenario. Mortality rate of 9 cardiac centers has been continuously monitored by a central clinical governance unit since 2010; prospectively collected monthly mortality rate of calendar year 2013-2014 from each center was used to retrospectively build an exponentially weighted moving average chart; mortality level was set at 4% as per threshold defined by the Italian Ministry of Health recommendation; upper CLs were set as 1.5 standard deviation from the specified level; lowest mortality rate (2.6%) was observed during calendar year 2012-2013, hence that was considered the center of the chart. All centers were considered as 1 entity and consecutively plotted in the chart following a geographic distribution, from North to South. A total number of 4049 operations were performed; 108 patients died while in hospital (2.6%). Different mortality trends that consisted of minor and major out-of-control process defined as a point of the chart outside the upper CLs were demonstrated. In conclusion, mortality trends could have been potentially identified at earlier time points before reaching the 4% limits of mortality; exponentially weighted and controlled chart may facilitate clinical governance units to their monitoring role.

International audience; Importance - The natural history and the management of patients with asymptomatic aortic stenosis (AS) have not been fully examined in the current era. Objective - To determine the clinical outcomes of patients with asymptomatic AS using data from the Heart Valve Clinic International Database. Design, setting, and participants - This registry was assembled by merging data from prospectively gathered institutional databases from 10 heart valve clinics in Europe, Canada, and the United States. Asymptomatic patients with an aortic valve area of 1.5 cm2 or less and preserved left ventricular ejection fraction (LVEF) greater than 50% at entry were considered for the present analysis. Data were collected from January 2001 to December 2014, and data were analyzed from January 2017 to July 2018. Main outcomes and measures - Natural history, need for aortic valve replacement (AVR), and survival of asymptomatic patients with moderate or severe AS at entry followed up in a heart valve clinic. Indications for AVR were based on current guideline recommendations. Results - Of the 1375 patients included in this analysis, 834 (60.7%) were male, and the mean (SD) age was 71 (13) years. A total of 861 patients (62.6%) had severe AS (aortic valve area less than 1.0 cm2). The mean (SD) overall survival during medical management (mean [SD] follow up, 27 [24] months) was 93% (1%), 86% (2%), and 75% (4%) at 2, 4, and 8 years, respectively. A total of 104 patients (7.6%) died under observation, including 57 patients (54.8%) from cardiovascular causes. The crude rate of sudden death was 0.65% over the duration of the study. A total of 542 patients (39.4%) underwent AVR, including 388 patients (71.6%) with severe AS at study entry and 154 (28.4%) with moderate AS at entry who progressed to severe AS. Those with severe AS at entry who underwent AVR did so at a mean (SD) of 14.4 (16.6) months and a median of 8.7 months. The mean (SD) 2-year and 4-year AVR-free survival rates for asymptomatic patients with severe AS at baseline were 54% (2%) and 32% (3%), respectively. In those undergoing AVR, the 30-day postprocedural mortality was 0.9%. In patients with severe AS at entry, peak aortic jet velocity (greater than 5 m/s) and LVEF (less than 60%) were associated with all-cause and cardiovascular mortality without AVR; these factors were also associated with postprocedural mortality in those patients with severe AS at baseline who underwent AVR (surgical AVR in 310 patients; transcatheter AVR in 78 patients). Conclusions and relevance - In patients with asymptomatic AS followed up in heart valve centers, the risk of sudden death is low, and rates of overall survival are similar to those reported from previous series. Patients with severe AS at baseline and peak aortic jet velocity of 5.0 m/s or greater or LVEF less than 60% have increased risks of all-cause and cardiovascular mortality even after AVR. The potential benefit of early intervention should be considered in these high-risk patients.

The reimplantation technique for valve sparing aortic root replacement is increasingly used to treat aortic root enlargement. The systematic approach described by El Khoury in 2009 and modified in 2011 using the valsava graft (Gelweave valsalva, Sultzer, Vaskutek, renfrewshire, Scotland) is simple and reproducible. However, in-conduit suturing of the aortic valve annulus and small rim of sinus remnant to the graft sinuses is time consuming and may lead to bleeding, or distorsion of the native valve in the prosthetic root. We describe a simple technique to facilitate the native valve reimplantation. A reproducible, easy to achieve single inflow suture line is used allowing avoiding the continuous suture of the native valve used in all valve sparing surgical techniques.
