Objectives Perivalvular abscesses with destruction of the aortomitral junction (AMJ) are a severe complication of infective endocarditis (IE) and are associated with high mortality and complex management. The Hemi-Commando procedure is a mitral valve (MV) sparing alternative to the Commando procedure in suitable patients with complex IE and paravalvular destruction. This study reviews the mid-term outcomes in patients undergoing the Hemi-Commando procedure for treating IE with destruction of the AMJ. Methods The clinical outcomes of patients with IE and AMJ involvement who underwent the Hemi-Commando procedure between 2015 and 2021 at the Leipzig Heart Center were retrospectively analyzed. Primary outcomes were 30-day mortality and 1-year survival. Secondary outcome was 1-year freedom from reoperation. Results A total of 22 patients underwent the Hemi-Commando procedure during the study period. The patients’ mean age was 59.8 ± 18.3 years. The study population was predominantly male (86.4%). Preoperative-sepsis was present in 6 (27.3%) patients, and the median EuroScore II was 28.5%. Almost two-thirds (N = 14; 63.6%) of the patients presented with native IE. Streptococci were the most common pathogens (N = 8; 36.4%). Paravalvular abscess was found intraoperatively in 16 (72.7%) patients. The 30-day mortality was 13.6%. The estimated 1- and 3-year survival rates were 77.5% and 66.4%, respectively. The estimated freedom from reoperation at 1 and 3 years was 92.3%. Conclusion The Hemi-Commando procedure offers an acceptable mid-term survival chance with low reoperation rates and is, therefore, a reasonable MV-sparing alternative to the Commando procedure in suitable patients with extensive IE and perivalvular involvement.

Background Large-bore arteriotomies can be percutaneously closed with suture-based or plug-based vascular closure device (VCD) strategies. The efficacy of both techniques remains controversial. Aims We conducted a meta-analysis of comparative studies between both VCD strategies, focusing on the most commonly applied VCDs (MANTA and ProGlide). Methods We searched MEDLINE, the Cochrane Central Register of Controlled Trials and Google scholar for observational studies (OS) and randomized controlled trials (RCT) comparing vascular closure with the MANTA-based and the ProGlide-based technique. The principal endpoint of this analysis was access-site related vascular complications. Both study types were analyzed separately. Results Access-site related vascular complications were less frequent after vascular closure with the MANTA technique in the analysis of OS (RR 0.61 [95%CI 0.43–0.89], p = 0.01, I2 = 0%), but more frequent in the analysis of RCT data (RR 1.70 [95%CI 1.16–2.51], p = 0.01, I2 = 0%). Both data sets provided no significant difference between the VCD techniques in terms of overall bleeding events (OS: RR 0.57 [95%CI 0.32–1.02], p = 0.06, I2 = 70%; and RCT: RR 1.37 [95%CI 0.82–2.28], p = 0.23, I2 = 30%). RCT data showed that endovascular stenting or vascular surgery due to VCD failure occurred more often after MANTA application (RR 3.53 [95%CI 1.07–11.33], p = 0.04, I2 = 0%). Conclusions While OS point to favorable outcomes for large-bore vascular closure with the MANTA-based technique, RCT data show that this strategy is associated with more access-site related vascular complications as well as endovascular stenting or vascular surgery due to device failure compared with the ProGlide-based technique.

Objective In transcatheter aortic valve implantation (TAVI), intraprocedural complications, which are only manageable by conversion to emergency open-heart surgery (E-OHS), occasionally occur. Contemporary data on the incidence and outcome of TAVI patients undergoing E-OHS are scarce. Methods Data of all patients undergoing transfemoral TAVI between 2006 and 2020 at the Heart Centre Leipzig were analyzed. The study time was divided into 3 periods: 2006–2010 (P1), 2011–2015 (P2), 2016–2020 (P3). Patients were grouped according to their surgical risk (high risk: EuroSCORE II ≥ 6%, low/intermediate risk: EuroSCORE II Results During the study period, a total of 6903 patients underwent transfemoral TAVI. Among them, 74 (1.1%) required E-OHS [high risk, n = 66 (89.2%); low/intermediate risk, n = 8 (10.8%)]. The rate of patients requiring E-OHS was 3.5% (20/577 patients), 1.8% (35/1967 patients), and 0.4% (19/4359 patients) in study periods P1-P3, respectively (p Conclusions In-hospital and 1-year survival rates following E-OHS are higher in low/intermediate risk than high risk TAVI patients. An on-site cardiac surgical department with immediately available E-OHS capabilities is an important component of the TAVI team.

ObjectiveWe sought to investigate whether long-term clinical outcomes differ following percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) in patients with three-vessel disease (3VD) and lesions in the proximal left anterior descending artery (P-LAD).MethodsThis post-hoc analysis of the Synergy between PCI with Taxus and Cardiac Surgery (SYNTAX) Extended Survival study included patients with 3VD who were classified according to the presence or absence of lesions located in the P-LAD. Ten-year all-cause death and 5-year major adverse cardiac or cerebrovascular events (MACCE) were assessed.ResultsAmong 1088 patients with 3VD, 559 (51.4%) had involvement of P-LAD and their 10-year mortality was numerically higher following PCI versus CABG (28.9% vs 21.9%; HR: 1.39, 95% CI 0.99 to 1.95). Although patients without P-LAD lesions had significantly higher 10-year mortality following PCI compared with CABG, there was no evidence of a treatment-by-subgroup interaction (28.8% vs 20.2%; HR: 1.47, 95% CI 1.03 to 2.09, pinteraction=0.837). The incidence of MACCE at 5 years was significantly higher with PCI than CABG, irrespective of involvement of P-LAD (with P-LAD: HR: 1.86, 95% CI 1.36 to 2.55; without P-LAD: HR: 1.54, 95% CI 1.11 to 2.12; pinteraction=0.408). Individualised assessment using the SYNTAX Score II 2020 established that a quarter of patients with P-LAD lesions had significantly higher mortality with PCI than CABG, whereas in the remaining three-quarters CABG had similar mortality.ConclusionsAmong patients with 3VD, the presence or absence of a P-LAD lesion was not associated with any treatment effect on long-term outcomes following PCI or CABG.Trial registration numberSYNTAXES:NCT03417050; SYNTAX:NCT00114972.

OBJECTIVES This study sought to evaluate the long-term differences in survival between multiple arterial grafts (MAG) and single arterial grafts (SAG) in patients who underwent coronary artery bypass grafting (CABG) in the SYNTAX study. METHODS The present analysis included the randomized and registry-treated CABG patients (n = 1509) from the SYNTAX Extended Survival study (SYNTAXES). Patients with only venous (n = 42) or synthetic grafts (n = 1) were excluded. The primary end point was all-cause death at the longest follow-up. Multivariable Cox regression was used to adjust for differences in baseline characteristics. Sensitivity analysis using propensity matching with inverse probability for treatment weights was performed. RESULTS Of the 1466 included patients, 465 (31.7%) received MAG and 1001 (68.3%) SAG. Patients receiving MAG were younger and at lower risk. At the longest follow-up of 12.6 years, all-cause death occurred in 23.6% of MAG and 40.0% of SAG patients [adjusted hazard ratio (HR) 0.74, 95% confidence interval (CI) (0.55–0.98); P = 0.038], which was confirmed by sensitivity analysis. MAG in patients with the three-vessel disease was associated with significant lower unadjusted and adjusted all-cause death at 12.6 years [adjusted HR 0.65, 95% CI (0.44–0.97); P = 0.033]. In contrast, no significance was observed after risk adjustment in patients with the left main disease, with and without diabetes, or among SYNTAX score tertiles. CONCLUSIONS In the present post hoc analysis of all-comers patients from the SYNTAX trial, MAG resulted in markedly lower all-cause death at 12.6-year follow-up compared to a SAG strategy. Hence, this striking long-term survival benefit of MAG over SAG encourages more extensive use of multiple arterial grafting in selected patients with reasonable life expectancy.

Background Vascular and bleeding complications are common after transcatheter aortic valve implantation (TAVI) and are associated with worse outcomes. The plug-based Manta (M) vascular closure device (VCD) is a novel option to achieve haemostasis for large-bore arterial access sites. Objective We aimed to compare vascular and bleeding complications between the M-VCD and the established suture-based Perclose ProGlide (P)-VCD. Methods From February to September 2019 a total of 578 patients underwent transfemoral TAVI at a single high-volume centre. Access site closure was performed using M-VCD in 195 patients (33.7%) and P-VCD in 383 patients (66.3%). We assessed vascular and access site-related complications as well as bleeding events according to the Valve Academic Research Consortium-2 definition. Results Overall vascular complications occurred less frequently in the M-VCD group (10.7% vs. 19.0%, p = 0.011) driven by a significantly lower rate of major vascular events (2.0% vs. 6.5%, p = 0.025). Access site-related complications were significantly less frequent in the M-VCD cohort (10.7% vs. 16.6%, p = 0.048). The M-VCD was associated with significantly lower rates of major (0.5% vs. 4.4%, p = 0.009) and life-threatening bleeding (0% vs. 2.3%, p = 0.032). In multivariable analysis, the use of M-VCD was the only independent predictor of vascular complications (odds ratio 0.54, 95% confidence interval 0.32–0.91, p = 0.022). Conclusions The M-VCD was associated with a reduction of vascular and access-site complications as well as severe bleeding after transfemoral TAVI compared to the P-VCD in this observational study.

Background: Transcatheter aortic valve replacement is an established treatment option for patients with severe symptomatic aortic stenosis and is most commonly performed through the transfemoral access route. Percutaneous access site closure can be achieved using dedicated plug-based or suture-based vascular closure device (VCD) strategies, but randomized comparative studies are scarce. Methods: The CHOICE-CLOSURE trial (Randomized Comparison of Catheter-based Strategies for Interventional Access Site Closure during Transfemoral Transcatheter Aortic Valve Implantation) is an investigator-initiated, multicenter study, in which patients undergoing transfemoral transcatheter aortic valve replacement were randomly assigned to vascular access site closure using either a pure plug-based technique (MANTA, Teleflex) with no additional VCDs or a primary suture-based technique (ProGlide, Abbott Vascular) potentially complemented by a small plug. The primary end point consisted of access site– or access-related major and minor vascular complications during index hospitalization, defined according to the Valve Academic Research Consortium-2 criteria. Secondary end points included the rate of access site– or access-related bleeding, VCD failure, and time to hemostasis. Results: A total of 516 patients were included and randomly assigned. The mean age of the study population was 80.5±6.1 years, 55.4% were male, 7.6% of patients had peripheral vascular disease, and the mean Society of Thoracic Surgeons score was 4.1±2.9%. The primary end point occurred in 19.4% (50/258) of the pure plug-based group and 12.0% (31/258) of the primary suture-based group (relative risk, 1.61 [95% CI, 1.07–2.44], P =0.029). Access site– or access-related bleeding occurred in 11.6% versus 7.4% (relative risk, 1.58 [95%CI: 0.91–2.73], P =0.133) and device failure in 4.7% versus 5.4% (relative risk, 0.86, [95% CI, 0.40–1.82], P =0.841) in the respective groups. Time to hemostasis was significantly shorter in the pure plug-based group (80 [32–180] versus 240 [174–316] seconds, P Conclusions: Among patients treated with transfemoral transcatheter aortic valve replacement, a pure plug-based vascular closure technique using the MANTA VCD is associated with a higher rate of access site– or access-related vascular complications but a shorter time to hemostasis compared with a primary suture-based technique using the ProGlide VCD.

Aim The aim of this study was to compare long-term all-cause mortality between patients receiving percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG) using multiple (MAG) or single arterial grafting (SAG). Methods and results The current study is a post hoc analysis of the SYNTAX Extended Survival Study, which compared PCI with CABG in patients with three-vessel (3VD) and/or left main coronary artery disease (LMCAD) and evaluated survival with ≥10 years of follow-up. The primary endpoint was all-cause mortality at maximum follow-up (median 11.9 years) assessed in the as-treated population. Of the 1743 patients, 901 (51.7%) underwent PCI, 532 (30.5%) received SAG, and 310 (17.8%) had MAG. At maximum follow-up, all-cause death occurred in 305 (33.9%), 175 (32.9%), and 70 (22.6%) patients in the PCI, SAG, and MAG groups, respectively (P Conclusion Our findings suggest that MAG might be the more desirable configuration for CABG to achieve lower long-term all-cause mortality than PCI in patients with 3VD and/or LMCAD.

Objectives Age-related atherosclerosis has been shown to cause aortic stiffness and wall rigidification. This analysis aimed to correlate age and dissection extension length in a large contemporary multi-centre study. We hypothesize that younger patients suffer more extensive DeBakey Type I dissection due to aortic wall integrity, allowing unhindered extension within the layers. Methods The perioperative data of 3385 patients from the German Registry for Acute Aortic Dissection Type A (GERAADA) were retrospectively analyzed with regard to postoperative outcomes and dissection extension. Patients with DeBakey Type I aortic dissection (n = 2510) were retrospectively identified and divided into two age-groups for comparison: ≤ 69 years (n = 1741) and ≥ 70years (n = 769). Patients with DeBakey type II dissection or connective tissue disease were excluded from the analysis. Results In younger patients (≤ 69 years), aortic dissection involved the supraaortic vessels significantly more often (52.0% vs. 40.1%; p Conclusions Extensive DeBakey Type I aortic dissection is less frequent in older patients ≥70 years than in younger patients. In contrast, younger patients suffer more often from preoperative organ malperfusion and associated complications. Postoperative mortality remains high irrespective of age-groups.

Background: The significant interaction between major infection and 5-year mortality after percutaneous coronary intervention (PCI) or coronary artery bypass graft (CABG) for complex coronary artery disease (CAD) was observed previously. However, the very long-term outcomes beyond 5 years remains unclear. Methods and results: This is a subgroup analysis of the SYNTAX Extended Survival (SYNTAXES) trial, which is the extended follow-up of the randomized SYNTAX trial comparing PCI versus CABG in patients with three-vessel disease (3VD) or left-main CAD (LMCAD). Out of 1517 patients enrolled in the SYNTAX trial with available survival status from 5 to 10 years, 140 patients had experienced major infections and survived at 5 years (major infection group). From 5 to 10 years, the mortality of major infection group was 19.8% whereas the mortality of no major infection group was 15.1% (p = 0.157). After the adjustment of other clinical factors, the risk of mortality from 5 to 10 years did not significantly differ between major infection and no major infection groups (HR: 1.10; 95% CI: 0.62–1.96; p = 0.740). When stratified by the presence or absence of periprocedural major infections, defined as a major infection within 60 days after index procedure, there was also no significant difference in 10-year mortality between two groups (30.8% vs. 24.5%; p = 0.057). Conclusions: Despite the initial association between major infections and 5 years mortality, postprocedural major infection was not evident in the 10 years follow-up, suggesting that the impact of major infection on mortality subsided over time beyond 5 years.

Objectives The aim of this study was to evaluate clinical characteristics, mechanisms of failure, and outcomes of transcatheter aortic valve replacement (TAVR) explantation. Background Surgical explantation following TAVR may be required for structural valve degeneration, paravalvular leak, infection, or other reasons. However, in-depth data on indications and outcomes are lacking. Methods Data from a multicenter, international registry (EXPLANT-TAVR) of patients who underwent TAVR explantation were reviewed retrospectively. Explantations performed during the same admission as initial TAVR were excluded. Clinical and echocardiographic outcomes were evaluated. Median follow-up duration was 6.7 months (interquartile range [IQR]: 1.0-18.8 months) after TAVR explantation and was 97.7% complete at 30 days and 86.1% complete at 1 year. Results From November 2009 to September 2020, 269 patients across 42 centers with a mean age of 72.7 ± 10.4 years underwent TAVR explantation. About one quarter (25.9%) were deemed low surgical risk at index TAVR, and median Society of Thoracic Surgeons risk at TAVR explantation was 5.6% (IQR: 3.2%-9.6%). The median time to explantation was 11.5 months (IQR: 4.0-32.4 months). Balloon-expandable and self-expanding or mechanically expandable valves accounted for 50.9% and 49.1%, respectively. Indications for explantation included endocarditis (43.1%), structural valve degeneration (20.1%), paravalvular leak (18.2%), and prosthesis-patient mismatch (10.8%). Redo TAVR was not feasible because of unfavorable anatomy in 26.8% of patients. Urgent or emergency cases were performed in 53.1% of patients, aortic root replacement in 13.4%, and 54.6% had concomitant cardiac procedures. Overall survival at last follow-up was 76.1%. In-hospital, 30-day, and 1-year mortality rates were 11.9%, 13.1%, and 28.5%, respectively, and stroke rates were 5.9%, 8.6%, and 18.7%, respectively. Conclusions The EXPLANT-TAVR registry reveals that surgical risks associated with TAVR explantation are not negligible and should be taken into consideration in the lifetime management of aortic stenosis.

Objectives The aim of this study was to determine clinical and echocardiographic characteristics, mechanisms of failure, and outcomes of mitral valve (MV) surgery after transcatheter edge-to-edge repair (TEER). Background Although >100,000 mitral TEER procedures have been performed worldwide, longitudinal data on MV surgery after TEER are lacking. Methods Data from the multicenter, international CUTTING-EDGE registry were retrospectively analyzed. Clinical and echocardiographic outcomes were evaluated. Median follow-up duration was 9.0 months (interquartile range [IQR]: 1.2-25.7 months) after MV surgery, and follow-up was 96.1% complete at 30 days and 81.1% complete at 1 year. Results From July 2009 to July 2020, 332 patients across 34 centers underwent MV surgery after TEER. The mean age was 73.8 ± 10.1 years, median Society of Thoracic Surgeons risk for MV repair at initial TEER was 4.0 (IQR: 2.3-7.3), and primary/mixed and secondary mitral regurgitation were present in 59.0% and 38.5%, respectively. The median interval from TEER to surgery was 3.5 months (IQR: 0.5-11.9 months), with overall median Society of Thoracic Surgeons risk of 4.8% for MV replacement (IQR: 2.8%-8.4%). The primary indication for surgery was recurrent mitral regurgitation (33.5%), and MV replacement and concomitant tricuspid surgery were performed in 92.5% and 42.2% of patients, respectively. The 30-day and 1-year mortality rates were 16.6% and 31.3%, respectively. On Kaplan-Meier analysis, the actuarial estimates of mortality were 24.1% at 1 year and 31.7% at 3 years after MV surgery. Conclusions In this first report of the CUTTING-EDGE registry, the mortality and morbidity risks of MV surgery after TEER were not negligible, and only

Numerous studies have demonstrated a paradoxical association between higher baseline body mass index (BMI) and lower long-term mortality risk after coronary revascularization, known as the “obesity paradox”, possibly relying on the single use of BMI. The current study is a post-hoc analysis of the SYNTAX Extended Survival (SYNTAXES) trial, which is the extended follow-up of the SYNTAX trial comparing percutaneous coronary intervention (PCI) versus coronary artery bypass graft (CABG) in patients with left-main coronary artery disease (LMCAD) or three-vessel disease (3VD). Patients were stratified according to baseline BMI and/or waist circumference (WC). Out of 1,800 patients, 1,799 (99.9%) and 1,587 (88.2%) had available baseline BMI and WC data, respectively. Of those, 1,327 (73.8%) patients had High BMI (≥25 kg/m2), whereas 705 (44.4%) patients had High WC (>102 cm for men or >88 cm for women). When stratified by both BMI and WC, 10-year mortality risk was significantly higher in patients with Low BMI/Low WC (adjusted hazard ratio [HR]: 1.65; 95% confidence interval [CI]: 1.09 to 2.51), Low BMI/ High WC (adjusted HR: 2.74; 95% CI: 1.12 to 6.69), or High BMI/High WC (adjusted HR: 1.59; 95% CI: 1.11 to 2.27) compared to those with High BMI/Low WC. In conclusion, the “obesity paradox” following coronary revascularization would be driven by low long-term mortality risk of the High BMI/Low WC group. Body composition should be assessed by the combination of BMI and WC in the appropriate evaluation of the long-term risk of obesity in patients with LMCAD or 3VD.

Background: The benefit of optimal medical therapy (OMT) on 5-year outcomes in patients with 3-vessel disease and/or left main disease after percutaneous coronary intervention or coronary artery bypass grafting (CABG) was demonstrated in the randomized SYNTAX (Synergy Between PCI With Taxus and Cardiac Surgery) trial. Objectives: The objective of this analysis is to assess the impact of the status of OMT at 5 years on 10-year mortality after percutaneous coronary intervention or CABG. Methods: This is a subanalysis of the SYNTAXES (Synergy Between PCI With Taxus and Cardiac Surgery Extended Survival) study, which evaluated for up to 10 years the vital status of patients who were originally enrolled in the SYNTAX trial. OMT was defined as the combination of 4 types of medications: at least 1 antiplatelet drug, statin, angiotensin-converting enzyme inhibitor/angiotensin receptor blocker, and beta-blocker. After stratifying participants by the number of individual OMT agents at 5 years and randomized treatment, a landmark analysis was conducted to assess the association between treatment response and 10-year mortality. Results: In 1,472 patients, patients on OMT at 5 years had a significantly lower mortality at 10 years compared with those on ≤2 types of medications (13.1% vs 19.9%; adjusted HR: 0.470; 95% CI: 0.292-0.757; P = 0.002) but had a mortality similar to those on 3 types of medications. Furthermore, patients undergoing CABG with the individual OMT agents, antiplatelet drug and statin, at 5 years had lower 10-year mortality than those without. Conclusions: In patients with 3-vessel and/or left main disease undergoing percutaneous coronary intervention or CABG, medication status at 5 years had a significant impact on 10-year mortality. Patients on OMT with guideline-recommended pharmacologic therapy at 5 years had a survival benefit.

OBJECTIVES The aim of this study was to analyse the early- and mid-term outcomes after redo surgical aortic valve replacement (SAVR) in patients with previous transcatheter aortic valve implantation (TAVI). METHODS Retrospective single-centre analysis of early- and mid-term outcomes following redo SAVR in patients with previous TAVI between 2013 and 2020. Primary outcomes were in-hospital mortality and mid-term survival. RESULTS During the study period, a total of 5756 patients underwent TAVI. Among them, 28 (0.5%) patients required redo SAVR after TAVI. During periods 2013–2016 and 2017–2020, 4/2184 (0.2%) patients and 24/3572 (0.7%) patients required SAVR after TAVI, respectively. The median logistic EuroSCORE was significantly higher at the time of SAVR than at the time of the index TAVI (5.9% vs 11.6%; P CONCLUSIONS SAVR can be successfully performed in patients with prior TAVI despite the increased surgical risk and technical difficulty. IE is associated with decreased mid-term survival.

Background: The optimal revascularization strategy for the elderly with complex coronary artery disease remains unclear. Objectives: The goal of this study was to investigate 10-year all-cause mortality, life expectancy, 5-year major adverse cardiac or cerebrovascular events (MACCE), and 5-year quality of life (QOL) after percutaneous coronary intervention (PCI) or coronary artery bypass graft (CABG) in elderly individuals (>70 years old) with 3-vessel disease (3VD) and/or left main disease (LMD). Methods: In the present pre-specified analysis on age of the SYNTAX Extended Survival study, 10-year all-cause death and 5-year MACCE were compared with Kaplan-Meier estimates and Cox proportional hazards models among elderly or nonelderly patients. Life expectancy was estimated by restricted mean survival time within 10 years, and QOL status according to the Seattle Angina Questionnaire up to 5 years was assessed by linear mixed-effects models. Results: Among 1,800 randomized patients, 575 patients (31.9%) were elderly. Ten-year mortality did not differ significantly between PCI and CABG in elderly (44.1% vs. 41.1%; hazard ratio [HR]: 1.08; 95% confidence interval [CI]: 0.84 to 1.40) and nonelderly patients (21.1% vs. 16.6%; HR: 1.30; 95% CI: 1.00 to 1.69; pinteraction = 0.332). Among elderly patients, 5-year MACCE was comparable between PCI and CABG (39.4% vs. 35.1%; HR: 1.18; 95% CI: 0.90 to 1.56), whereas it was significantly higher in PCI over CABG among nonelderly patients (36.3% vs. 23.0%; HR: 1.69; 95% CI: 1.36 to 2.10; pinteraction = 0.043). There were no significant difference in life expectancy (mean difference: 0.2 years in favor of CABG; 95% CI: −0.4 to 0.7) and 5-year QOL status between PCI and CABG among elderly patients. Conclusions: Elderly patients with 3VD and/or LMD had comparable 10-year all-cause death, life expectancy, 5-year MACCE, and 5-year QOL status irrespective of revascularization mode.

Background Acute Stanford type A aortic dissection (TAAD) is a life-threatening condition. Surgery is usually performed as a salvage procedure and is associated with significant postoperative early mortality and morbidity. Understanding the patient’s conditions and treatment strategies which are associated with these adverse events is essential for an appropriate management of acute TAAD. Methods Nineteen centers of cardiac surgery from seven European countries have collaborated to create a multicentre observational registry (ERTAAD), which will enroll consecutive patients who underwent surgery for acute TAAD from January 2005 to March 2021. Analysis of the impact of patient’s comorbidities, conditions at referral, surgical strategies and perioperative treatment on the early and late adverse events will be performed. The investigators have developed a classification of the urgency of the procedure based on the severity of preoperative hemodynamic conditions and malperfusion secondary to acute TAAD. The primary clinical outcomes will be in-hospital mortality, late mortality and reoperations on the aorta. Secondary outcomes will be stroke, acute kidney injury, surgical site infection, reoperation for bleeding, blood transfusion and length of stay in the intensive care unit. Discussion The analysis of this multicentre registry will allow conclusive results on the prognostic importance of critical preoperative conditions and the value of different treatment strategies to reduce the risk of early adverse events after surgery for acute TAAD. This registry is expected to provide insights into the long-term durability of different strategies of surgical repair for TAAD. Trial registration ClinicalTrials.gov Identifier: NCT04831073.

The purpose of this paper was to evaluate the impact of proportionality of secondary mitral regurgitation (SMR) in a large real-world registry of transcatheter edge-to-edge mitral valve repair (TMVr) BACKGROUND: Differences in the outcomes of recent randomized trials of TMVr for SMR may be explained by the proportionality of SMR severity to left ventricular (LV) volume.The ratio of pre-procedural effective regurgitant orifice area (EROA) to LV end-diastolic volume (LVEDV) was retrospectively assessed in patients undergoing TMVr for severe SMR between 2008 and 2019 from the EuroSMR registry. A recently proposed SMR proportionality scheme was adapted to stratify patients according to EROA/LVEDV ratio in 3 groups: MR-dominant (MD), MR-LV-co-dominant (MLCD), and LV-dominant (LD). All-cause mortality was assessed as a primary outcome, secondary heart failure (HF) outcomes included hospitalization for HF (HHF), New York Heart Association (NYHA) functional class, N-terminal pro-B-type natriuretic peptide (NT-proBNP), 6-min-walk distance, quality of life and MR grade.A total of 1,016 patients with an EROA/LVEDV ratio were followed for 22 months after TMVr. MR was reduced to grade ≤2+ in 92%, 96%, and 94% of patients (for MD, MLCD, and LD, respectively; p = 0.18). After adjustment for covariates including age, sex, diabetes, kidney function, body surface area, LV ejection fraction, and procedural MR reduction (grade ≤2+), adjusted rates of 2-year mortality in MD patients did not differ from those for MLCD patients (17% vs. 18%, respectively), whereas it was higher in LD patients (23%; p = 0.02 for comparison vs. MD+MLCD). The adjusted first HHF rate differed between groups (44% in MD, 56% in MLCD, 29% in LD; p = 0.01) as did the adjusted time for first death or HHF rate (66% in MD, 82% in MLCD, 68% in LD; p = 0.02). Improvement of NYHA functional class was seen in all groups (p 0.001). Values for 6-min-walk distances, quality of life and NT-proBNP improved in most patients.MD and MLCD patients had a comparable, adjusted 2-year mortality rate after TMVr which was slightly better than that of LD patients. Patients treated with TMVr had symptomatic improvement regardless of EROA/LVEDV ratio.

Background The efficacy of different cardioplegia solutions on outcomes of complex cardiac operations such as triple valve surgery (TVS) is scarce. Here we compared the outcomes in TVS patients receiving either crystalloid (Bretschneider) or blood (Calafiore) cardioplegia. Methods Screening of our institutional database with prospectively entered data identified 471 consecutive patients (mean age 70.3 ± 9.2 years; 50.9% male), who underwent TVS (replacement or repair of aortic, mitral and tricuspid valve) between December 1994 and January 2013. In 277 patients, cardiac arrest was induced with HTK-Bretschneider solution (HTK, n = 277, 58.8%), whereas 194 received cold blood cardioplegia (BCP) according to Calafiore ( n = 194, 41.2%). Comparisons of perioperative and follow up outcomes were made between cardioplegia groups. Results Preoperative patient characteristics and comorbidities were equally balanced between groups. 30-days mortality was similar between groups (HTK: 16.2%; BCP: 18.2%; p = 0.619). Incidence of the cumulative endpoint (30days mortality, myocardial infarction (MI), arrhythmia, low cardiac output syndrome or need for permanent pacemaker implantation) was also comparable (HTK: 47.6%; BCP: 54.8%, p = 0.149). In patients with reduced left ventricular ejection fraction (LVEF Conclusions Myocardial protection with HTK shows equivalent outcomes compared to BCP during TVS. Patients with reduced left ventricular function may benefit from BCP during TVS.

Background Mitral valve (MV) repair with annuloplasty is the standard of care in patients with primary degenerative mitral regurgitation (DMR). Newer generations of annuloplasty rings have been developed with the goals of closer reproduction of native annular geometry and easier implantation. This study investigates the short-term and 5-year clinical outcomes of MV repair with the Carpentier-Edwards (CE) Physio II annuloplasty ring. Methods This is an observational study including a total of 486 patients who underwent MV repair for DMR using the CE Physio II annuloplasty ring between 2011 and 2016. Results Mean age was 54.8 ± 12.1 years, 364 patients (74.9%) were males, and 84 patients (17.3%) presented with atrial fibrillation. Mean left ventricular ejection fraction was 62.3 ± 7.3%. Mean logistic EuroSCORE was 2.7 ± 2.4%. New York Heart Association functional class III–IV symptoms were present in 134 (27.6%) patients preoperatively. Isolated MV repair was performed via a right-sided mini-thoracotomy in 479 patients (98.6%). Concomitant procedures included ablation for atrial fibrillation in 83 patients (17.1%) and closure of atrial septum defect in 88 patients (18.1%). Median size of implanted annuloplasty rings was 34 mm (interquartile range: 34–38 mm). Mean cardiopulmonary bypass time was 116 ± 34 minutes and mean cross-clamp time was 74 ± 25 minutes. Thirty-day mortality was 0.4%. The Kaplan–Meier 4-year survival was 98.5%. Freedom from MV reoperation was 96.2 and 94.0% at 1 and 4 years. Conclusion MV repair with the CE Physio II annuloplasty ring is associated with excellent midterm clinical outcome.

Background: The long-term clinical benefit after percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) in patients with total occlusions (TOs) and complex coronary artery disease has not yet been clarified. Objectives: The objective of this analysis was to assess 10-year all-cause mortality in patients with TOs undergoing PCI or CABG. Methods: This is a subanalysis of patients with at least 1 TO in the SYNTAXES (Synergy Between PCI With Taxus and Cardiac Surgery Extended Survival) study, which investigated 10-year all-cause mortality in the SYNTAX (Synergy Between PCI With Taxus and Cardiac Surgery) trial, beyond its original 5-year follow-up. Patients with TOs were further stratified according to the status of TO recanalization or revascularization. Results: Of 1,800 randomized patients to the PCI or CABG arm, 460 patients had at least 1 lesion of TO. In patients with TOs, the status of TO recanalization or revascularization was not associated with 10-year all-cause mortality, irrespective of the assigned treatment (PCI arm: 29.9% vs. 29.4%; adjusted hazard ratio [HR]: 0.992; 95% confidence interval [CI]: 0.474 to 2.075; p = 0.982; and CABG arm: 28.0% vs. 21.4%; adjusted HR: 0.656; 95% CI: 0.281 to 1.533; p = 0.330). When TOs existed in left main and/or left anterior descending artery, the status of TO recanalization or revascularization did not have an impact on the mortality (34.5% vs. 26.9%; adjusted HR: 0.896; 95% CI: 0.314 to 2.555; p = 0.837). Conclusions: At 10-year follow-up, the status of TO recanalization or revascularization did not affect mortality, irrespective of the assigned treatment and location of TOs. The present study might support contemporary practice among high-volume chronic TO-PCI centers where recanalization is primarily offered to patients for the management of angina refractory to medical therapy when myocardial viability is confirmed.

BACKGROUND Severe pulmonary hypertension is a relative contraindication for isolated tricuspid valve (TV) surgery. However, some patients may still benefit from TV surgery. We hypothesized that pulmonary pressure alone is an inadequate predictor of outcomes post-TV surgery, and that aorto-pulmonary pressure quotient (AoP/PAP) is a better predictor. METHODS From 2005 to 2019, a total of 122 patients (mean age: 68.5±10.5 years; 43.3% male) with isolated TV regurgitation and preoperative right heart catheterization referred to our institution for isolated TV surgery were included. Patients with concomitant procedures were excluded from this analysis. All data were retrospectively analyzed. Follow-up was 97% complete. RESULTS The mean follow-up time was 4.3±3.6 years. The mean preoperative New York Heart Association (NYHA) class was 2.9±0.7, left ventricular ejection fraction was 52.3±11.3%, creatinine level was 124.8±102.6μmol/l, mean pulmonary artery pressure was 25.5±9.4mmHg, mean MELD-XI score 13.5±4.2, and mean AoP/PAP was 4.1±1.9 mmHg. Thirty-day mortality was 10.9%, and 5-years survival was 56.6±4.9%. Cox regression analysis revealed age (p=0.001; HR: 1.058; CI 95%: 1.023-1.094), the mean arterial pressure (p=0.002; HR: 0.969; CI 95%: 0.950-0.988) and systolic pulmonary artery pressure (p=0.035; HR: 1.054; CI 95%: 1.004-1.107), as well as mean AoP/PAP > 4 (p=0.001; HR: 6.678; CI 95%: 2.197-20.294) as predictors for long-term mortality. CONCLUSIONS Regardless of the degree of pulmonary hypertension, a mean AoP/PaP quotient >4 impacts the postoperative survival of patients undergoing isolated TV surgery. However, further research is still required to verify this finding.

BACKGROUND We report on four patients with severe tricuspid valve (TV) regurgitation, in which a differentiated intraoperative transoesophageal echocardiographic (TEE) analysis - as performed in TV-clipping procedures - provided major guidance for refined TV repair. METHODS Between January 2019 and March 2020, four patients with central tricuspid regurgitation and an intercommisural jet underwent annuloplasty with an echo-guided plication stitch on the affected leaflet basis, especially anteroseptal. RESULTS All patients underwent complex multiple valve (aortic- and/or mitral valve) surgery with concomitant TV-repair. No or mild TV regurgitation after TV repair was confirmed in the predischarge echocardiography in all patients. CONCLUSIONS We conclude, that differentiated intraoperative TEE is essential for the surgical TV repair strategy. Plication of the anteroseptal commissure - additionally performed to TV annuloplasty - is an easy and effective add-on in selected patients.

We present a two-dimensional kinematic description of the geometry and dynamics of the ropes of demersal seines during deployment, towing, and hauling, using piriform curves. Piriforms (which means pear shaped) are relatively simple analytical curves, which we parameterize, using basic positional and operational data from typical Danish anchor seine hauls. We then demonstrate how we can estimate the area fished, and the speed, direction and angle of attack of any part of the seine net rope, at any time during the fishing process. This sort of information is fundamental to a better understanding of the capture process of demersal seines, their whole gear selectivity, and their environmental impact.

Severe mitral annular calcification (MAC) may represent a challenging issue which can lead to poor outcomes and serious issues such as patient-prosthesis mismatch (PPM). The potential harmful effect of PPM must be prevented through the use of alternative techniques that allow mitral valve replacement with adequately sized bioprostheses in patients with MAC. PPM should be recognized as a contraindication for transcatheter valve-in-valve replacement as it leads to poor outcomes and early prosthetic degeneration.

Background: The poorer prognosis of coronary artery disease in females compared with males is related mainly to differences in baseline characteristics. In the SYNTAX (Synergy Between Percutaneous Coronary Intervention With Taxus and Cardiac Surgery) trial, the effect of treatment with percutaneous coronary intervention (PCI) versus coronary artery bypass grafting surgery (CABG) on mortality at 5 years differed significantly between females and males; however, the optimal revascularization beyond 5 years according to sex has not been evaluated. Objectives: The aim of this study was to investigate the impact of sex on mortality and sex-treatment interaction at 10 years. Methods: The SYNTAXES (SYNTAX Extended Survival) study evaluated vital status up to 10 years in 1,800 patients with de novo 3-vessel and/or left main coronary artery disease randomized to treatment with PCI or CABG in the SYNTAX trial. All-cause death at 10 years was separately evaluated in female and male patients with complex coronary artery disease. Results: Of 1,800 patients, 402 (22.3%) were female and 1,398 (77.7%) were males. Females had a higher 10-year mortality rate compared with males (32.8% vs. 24.7%; log-rank p = 0.002), but female sex was not an independent predictor of mortality (adjusted hazard ratio: 1.02; 95% confidence interval: 0.76 to 1.36). Mortality at 10 years tended to be lower after CABG than after PCI, with a similar treatment effect for female and male patients (adjusted hazard ratio for females: 0.90 [95% confidence interval: 0.54 to 1.51]; adjusted hazard ratio for males: 0.76 [95% confidence interval: 0.56 to 1.02]; p for interaction = 0.952). Conclusions: Female sex was not an independent predictor of mortality at 10 years in patients with complex coronary artery disease. The interaction between sex and treatment with PCI or CABG that was observed at 5 years was no longer present at 10 years.

OBJECTIVES Non-leaflet resection techniques including loop chordal replacement are being used with increasing frequency, but the long-term results of these techniques are still unknown. The aim of this study was to compare the long-term results of loop neochord replacement with leaflet resection techniques in patients undergoing minimally invasive mitral valve (MV) repair for MV prolapse. METHODS Between 1999 and 2014, 2134 consecutive MV prolapse patients underwent minimally invasive MV repair with isolated loop (n = 1751; 82.1%) or resection techniques (n = 383, 17.9%) at our institution. Follow-up data were available for 86% of patients with a mean follow-up time of 6.1 ± 4.3 years. RESULTS The 30-day mortality was 0.8% for all patients (loop: 0.7%, resection: 1.6%; P = 0.09). Leaflet resection was associated with more moderate or more mitral regurgitation on predischarge echocardiography (P = 0.003). The 1-, 5- and 10-year survival rates were 98 ± 1%, 95 ± 1% and 86 ± 2% for the loop technique versus 97 ± 1%, 92 ± 1% and 81 ± 2% for resection patients, respectively (P = 0.003). Significant predictors for late mortality were MV repair technique (P = 0.004), left ventricular ejection fraction (P CONCLUSIONS In our patient cohort, MV repair with loop chordal replacement is associated with less early recurrent mitral regurgitation and very good long-term results when compared to classical leaflet resection techniques for MV prolapse and is therefore an excellent option for such patients.

Aims Patients with pulmonary hypertension (PHT) are often excluded from surgical therapies for tricuspid regurgitation (TR). Transcatheter tricuspid valve repair (TTVR) with the MitraClip™ technique is a novel treatment option for these patients. We aimed to assess the role of PHT in severe TR and its implications for TTVR. Methods and results A total of 243 patients underwent TTVR at two centres. One hundred twenty-one patients were grouped as iPHT+ [invasive systolic pulmonary artery pressures (PAPs) ≥50 mmHg]. Patients were similarly stratified according to echocardiographic PAPs (ePHT). The occurrence of the combined clinical endpoint (death, heart failure hospitalization, and reintervention) was investigated during a follow-up of 330 (interquartile range 175–402) days. iPHT+ patients were at higher preoperative risk (P Conclusion The discordant echocardiographic and invasive diagnosis of PHT in severe TR predicts outcomes after TTVR.

Aims To characterize the prevalence and clinical relevance of malnutrition in patients undergoing transcatheter tricuspid valve edge-to-edge repair (TTVR). Methods and results Overall, 86 consecutive patients (mean age 78 ± 7 years) with moderate-to-severe tricuspid regurgitation (TR) at prohibitive surgical risk were analysed. Mini Nutritional Assessment (MNA), quality of life assessment, 6-min walk test distance and laboratory analyses were performed before and 1 month after TTVR. A total of 43 patients (50%) underwent concomitant transcatheter mitral valve repair. According to MNA, 81 patients (94%) were malnourished or at risk of malnutrition before TTVR. Following TTVR, MNA improved in 64 patients (74%). As compared to patients without MNA improvement, patients with increased MNA score had greater reductions in TR [regurgitation volume −17.0 (interquartile range, IQR −25.0; −7.0) mL vs. −26.4 (IQR −40.3; −14.5) mL, P

We sought to determine outcomes of aortic valve replacement (AVR) versus root replacement after transcatheter AVR (TAVR) explantation because they remain unknown.From November 2009 to September 2020, data from the EXPLANT-TAVR International Registry of patients who underwent TAVR explant were retrospectively reviewed, divided by AVR versus root replacement. After excluding explants performed during the same admission as the initial TAVR and concomitant procedures involving the other valves, 168 AVR cases were compared with 28 root replacements, and outcomes were reported at 30 days and 1 year.Among 196 patients (mean age, 73.5 ± 9.9 years) who had primary aortic valve intervention at TAVR explant, the median time from TAVR to surgical explant was 11.2 months (interquartile range, 4.4-32.9 months). Indications for explant were similar between the 2 groups. Compared with AVR, patients requiring root replacement had fewer comorbidities but more unfavorable anatomy for redo TAVR (52.6% vs 26.4%; P = .032), fewer urgent/emergency cases (32.1% vs 58.3%; P = .013), longer median interval from index TAVR to TAVR explant (17.6 vs 9.9 months; P = .047), and more concomitant ascending aortic replacement (58.8% vs 14.0%; P .001). Median follow-up was 6.9 months (interquartile range, 1.4-21.6 months) after TAVR explant and 97.4% complete. Overall survival at follow-up was 81.2% with no differences between groups (log rank P = .54). In-hospital, 30-day, and 1-year mortality rates and stroke rates were not different between the 2 groups.In the EXPLANT-TAVR Registry, AVR and root replacement groups had different clinical characteristics, but no differences in short-term mortality and morbidities. Further investigations are necessary to identify patients at risk of root replacement in TAVR explant.

OBJECTIVES Surgery of the aortic root in acute aortic dissection type A (AADA) remains a topic of vague evidence since the extend of dissection and surgeons’ capability and interpretation of the disease vary remarkably. We aimed to interpret root operation strategies in the German Registry for Acute Aortic Dissection cohort. METHODS German Registry for Acute Aortic Dissection collected the data of 56 centres between July 2006 and June 2015. A total of 3382 patients undergoing operations for AADA were included and divided into 3 groups according to aortic root procedure types: supracommissural replacement (SCR), conduit replacement (CR) and valve sparing root replacement (VSRR). RESULTS Patients in SCR (2425, 71.7%) were significantly older than CR (681, 20.1%) and VSRR (276, 8.2%) (63.4 vs 57.5 vs 54.2 years; P CONCLUSIONS SCR remains the procedure of choice in elderly and compromised patients. Extended root preservation techniques may be applied even in combination with extended aortic arch surgery for selected patients for AADA with promising early outcomes.

Objectives: The aim of this study was to assess 10-year all-cause mortality in patients with heavily calcified lesions (HCLs) undergoing percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG). Background: Limited data are available on very long term outcomes in patients with HCLs according to the mode of revascularization. Methods: This substudy of the SYNTAXES (Synergy Between PCI With Taxus and Cardiac Surgery Extended Survival) study assessed 10-year all-cause mortality according to the presence of HCLs within lesions with >50% diameter stenosis and identified during the calculation of the anatomical SYNTAX (Synergy Between PCI With Taxus and Cardiac Surgery) score among 1,800 patients with the 3-vessel disease and/or left main disease randomized to PCI or CABG in the SYNTAX trial. Patients with HCLs were further stratified according to disease type (3-vessel disease or left main disease) and assigned treatment (PCI or CABG). Results: The 532 patients with ≥1 HCL had a higher crude mortality rate at 10 years than those without (36.4% vs 22.3%; HR: 1.79; 95% CI: 1.49-2.16; P < 0.001). After adjustment, an HCL remained an independent predictor of 10-year mortality (HR: 1.36; 95% CI: 1.09-1.69; P = 0.006). There was a significant interaction in mortality between treatment effect (PCI and CABG) and the presence or absence of HCLs (Pinteraction = 0.005). In patients without HCLs, mortality was significantly higher after PCI than after CABG (26.0% vs 18.8%; HR: 1.44; 95% CI: 0.97-1.41; P = 0.003), whereas in those with HCLs, there was no significant difference (34.0% vs 39.0%; HR: 0.85; 95% CI: 0.64-1.13; P = 0.264). Conclusions: At 10 years, the presence of an HCL was an independent predictor of mortality, with a similar prognosis following PCI or CABG. Whether HCLs require special consideration when deciding the mode of revascularization beyond their current contribution to the anatomical SYNTAX score deserves further evaluation.
