Objectives: The goal of this project was to assess the efficacy of a reoperative frozen elephant trunk (FET) operation for treating residual type A aortic dissections., Methods: Between April 2015 and October 2023, a total of 237 patients underwent elective redo surgical aortic arch replacement via the FET technique to treat residual type A aortic dissection in 11 European aortic centres. Data were pooled and analysed retrospectively., Results: The time between an acute type A dissection repair to an FET implant was 5 years. More than half of all patients (54%) presented with an entry within the aortic arch, and 174 patients (73%) presented residual dissections of supra-aortic vessels. During FET repair, the axillary artery was cannulated in 181 patients (76%), whereas 83 patients (35%) underwent additional cardiac procedures including 39 root replacements (16%) and 15 coronary bypass procedures (6%). Zone 2 was the most common arch anastomosis site (n = 163, 69%), and bilateral antegrade cerebral perfusion was most frequent (n = 159, 67%). Fifteen patients (6%) died in-hospital. Age in years (P < 0.001, odds ratio: 1.069) proved to be predictive for overall mortality in our Cox regression model., Conclusions: Elective redo surgical aortic arch replacement using the FET technique for treating residual type A aortic dissection following ascending aortic replacement revealed a favourable outcome. The decision to undertake stage two therapy of a residually dissected aortic arch should be made by an aortic team on a patient-by-patient basis., (© The Author(s) 2024.

Objectives: Gender difference in the outcome after type A aortic dissection (TAAD) surgery remains an issue of ongoing debate. In this study, we aimed to evaluate the impact of gender on the short- and long-term outcome after surgery for TAAD., Methods: A multicentre European registry retrospectively included all consecutive TAAD surgery patients between 2005 and 2021 from 18 hospitals across 8 European countries. Early and late mortality, and cumulative incidence of aortic reoperation were compared between genders., Results: A total of 3902 patients underwent TAAD surgery, with 1185 (30.4%) being females. After propensity score matching, 766 pairs of males and females were compared. No statistical differences were detected in the early postoperative outcome between genders. Ten-year survival was comparable between genders (47.8% vs 47.1%; log-rank test, P = 0.679), as well as cumulative incidences of distal or proximal aortic reoperations. Ten-year relative survival compared to country-, year-, age- and sex-matched general population was higher among males (0.65) compared to females (0.58). The time-period subanalysis revealed advancements in surgical techniques in both genders over the years. However, an increase in stroke was observed over time for both populations, particularly among females., Conclusions: The past 16 years have witnessed marked advancements in surgical techniques for TAAD in both males and females, achieving comparable early and late mortality rates. Despite these findings, late relative survival was still in favour of males., (© The Author(s) 2024.

Background: Extended aortic repair is considered a key issue for the long-term durability of surgery for DeBakey type 1 aortic dissection. The risk of aortic degeneration may be higher in young patients due to their long life expectancy. The early outcome and durability of aortic surgery in these patients were investigated in the present study., Methods: The subjects of the present analysis were patients under 60 years old who underwent surgical repair for acute DeBakey type 1 aortic dissection at 18 cardiac surgery centres across Europe between 2005 and 2021. Patients underwent ascending aortic repair or total aortic arch repair using the conventional technique or the frozen elephant trunk technique. The primary outcome was 5-year cumulative incidence of reoperation on the distal aorta., Results: Overall, 915 patients underwent surgical ascending aortic repair and 284 patients underwent surgical total aortic arch repair. The frozen elephant trunk procedure was performed in 128 patients. Among 245 propensity score-matched pairs, total aortic arch repair did not decrease the rate of distal aortic reoperation compared to ascending aortic repair (5-year cumulative incidence, 6.7% versus 6.7%, subdistributional hazard ratio 1.127, 95% c.i. 0.523 to 2.427). Total aortic arch repair increased the incidence of postoperative stroke/global brain ischaemia (25.7% versus 18.4%, P = 0.050) and dialysis (19.6% versus 12.7%, P = 0.003). Five-year mortality was comparable after ascending aortic repair and total aortic arch repair (22.8% versus 27.3%, P = 0.172)., Conclusions: In patients under 60 years old with DeBakey type 1 aortic dissection, total aortic arch replacement compared with ascending aortic repair did not reduce the incidence of distal aortic operations at 5 years. When feasible, ascending aortic repair for DeBakey type 1 aortic dissection is associated with satisfactory early and mid-term outcomes., Trial Registration: ClinicalTrials.gov Identifier: NCT04831073., (© The Author(s) 2024.

Objectives: We herein report a single-centre experience with the SAPIEN 3 Ultra balloon-expandable transcatheter aortic valve implantation (TAVI) system., Methods: Between March 2019 and January 2020, a total of 79 consecutive patients received transfemoral TAVI using the SAPIEN 3 Ultra device. Data were retrospectively analysed according to updated Valve Academic Research Consortium-2 definitions. Detailed analysis of multislice computed tomography data was conducted to identify potential predictors for permanent pacemaker (PPM) implantation and residual paravalvular leakage (PVL) post TAVI., Results: Device success and early safety were 97.5% (77/79) and 94.9% (75/79) with resulting transvalvular peak/mean pressure gradients of 21.1 ± 8.2/10.9 ± 4.4 and PVL >mild in 0/79 patients (0%). Mild PVL was seen in 18.9% (15/79) of cases. Thirty-day mortality was 2.5% (2/79). The Valve Academic Research Consortium-2 adjudicated clinical end points disabling stroke, acute kidney injury and myocardial infarction occurred in 1.3% (1/79), 5.1% (4/79) and 0% (0/79) of patients. Postprocedural PPM implantation was necessary in 7.6% (6/79) of patients. Multislice computed tomography analysis revealed significantly higher calcium amounts of the right coronary cusp in patients in need for postprocedural PPM implantation and a higher eccentricity index in patients with postinterventional mild PVL., Conclusions: First experience with this newly designed balloon-expandable-transcatheter heart valve demonstrates adequate 30-day outcomes and haemodynamic results with low mortality, low rates of PPM implantation and no residual PVL >mild. The herein-presented multislice computed tomography values with an elevated risk for PPM implantation and residual mild PVL may help to further improve outcomes with this particular transcatheter heart valve in TAVI procedures., (© The Author(s) 2020.

Objectives: This study aims to investigate the incidence and determinants of major early adverse events in low-risk patients undergoing isolated coronary artery bypass grafting (CABG)., Methods: The multicentre E-CABG registry included 7352 consecutive patients who underwent isolated CABG from January 2015 to December 2016. Patients with an European System for Cardiac Operative Risk Evaluation (EuroSCORE) II of <2% and without any major comorbidity were the subjects of the present analysis., Results: Out of 2397 low-risk patients, 11 (0.46%) died during the index hospitalization or within 30 days from surgery. Five deaths were cardiac related, 4 of which were secondary to technical failures. We estimated that 8 out of 11 deaths were potentially preventable. Logistic regression model identified porcelain aorta [odds ratio (OR) 34.3, 95% confidence interval (CI) 1.3-346.3] and E-CABG bleeding grades 2-3 (OR 30.2, 95% CI 8.3-112.9) as independent predictors of hospital death., Conclusions: Mortality and major complications, although infrequently, do occur even in low-risk patients undergoing CABG. Identification of modifiable causes of postoperative adverse events may be useful to develop preventative strategies to improve the quality of care of patients undergoing cardiac surgery., Clinical Trial Registration: NCT02319083 (https://clinicaltrials.gov/ct2/show/NCT02319083)., (© The Author(s) 2020.
