RESUMEN
BACKGROUND: Among low-risk patients with severe, symptomatic aortic stenosis who are eligible for both transcatheter aortic-valve implantation (TAVI) and surgical aortic-valve replacement (SAVR), data are lacking on the appropriate treatment strategy in routine clinical practice. METHODS: In this randomized noninferiority trial conducted at 38 sites in Germany, we assigned patients with severe aortic stenosis who were at low or intermediate surgical risk to undergo either TAVI or SAVR. Percutaneous- and surgical-valve prostheses were selected according to operator discretion. The primary outcome was a composite of death from any cause or fatal or nonfatal stroke at 1 year. RESULTS: A total of 1414 patients underwent randomization (701 to the TAVI group and 713 to the SAVR group). The mean (±SD) age of the patients was 74±4 years; 57% were men, and the median Society of Thoracic Surgeons risk score was 1.8% (low surgical risk). The Kaplan-Meier estimate of the primary outcome at 1 year was 5.4% in the TAVI group and 10.0% in the SAVR group (hazard ratio for death or stroke, 0.53; 95% confidence interval [CI], 0.35 to 0.79; P<0.001 for noninferiority). The incidence of death from any cause was 2.6% in the TAVI group and 6.2% in the SAVR group (hazard ratio, 0.43; 95% CI, 0.24 to 0.73); the incidence of stroke was 2.9% and 4.7%, respectively (hazard ratio, 0.61; 95% CI, 0.35 to 1.06). Procedural complications occurred in 1.5% and 1.0% of patients in the TAVI and SAVR groups, respectively. CONCLUSIONS: Among patients with severe aortic stenosis at low or intermediate surgical risk, TAVI was noninferior to SAVR with respect to death from any cause or stroke at 1 year.

BACKGROUND AND AIMS: Surgical explantation of transcatheter heart valves (THVs) is rapidly increasing, but there are limited data on patients with THV-associated infective endocarditis (IE). This study aims to assess the outcomes of patients undergoing THV explant for IE. METHODS: All patients who underwent THV explant between 2011 and 2022 from 44 sites in the EXPLANT-TAVR registry were identified. Patients with IE as the reason for THV explant were compared to those with other mechanisms of bioprosthetic valve dysfunction (BVD). RESULTS: A total of 372 patients from the EXPLANT-TAVR registry were included. Among them, 184 (49.5%) patients underwent THV explant due to IE and 188 (50.5%) patients due to BVD. At the index transcatheter aortic valve replacement, patients undergoing THV explant for IE were older (74.3 ± 8.6 vs. 71 ± 10.6 years) and had a lower Society of Thoracic Surgeons risk score [2.6% (1.8-5.0) vs. 3.3% (2.1-5.6), P = .029] compared to patients with BVD. Compared to BVD, IE patients had longer intensive care unit and hospital stays (P < .05) and higher stroke rates at 30 days (8.6% vs. 2.9%, P = .032) and 1 year (16.2% vs. 5.2%, P = .010). Adjusted in-hospital, 30-day, and 1-year mortality was 12.1%, 16.1%, and 33.8%, respectively, for the entire cohort, with no significant differences between groups. Although mortality was numerically higher in IE patients 3 years postsurgery (29.6% for BVD vs. 43.9% for IE), Kaplan-Meier analysis showed no significant differences between groups (P = .16). CONCLUSIONS: In the EXPLANT-TAVR registry, patients undergoing THV explant for IE had higher 30-day and 1-year stroke rates and longer intensive care unit and hospital stays. Moreover, patients undergoing THV explant for IE had a higher 3-year mortality rate, which did not reach statistical significance given the relatively small sample size of this unique cohort and the reduced number of events.

OBJECTIVES: To analyze outcomes in patients with normal preoperative left ventricular ejection fraction (LVEF) undergoing venoarterial extracorporeal membrane oxygenation (VA-ECMO) therapy due to postcardiotomy cardiogenic shock (PCCS) related to coronary malperfusion. METHODS: Retrospective single-center analysis in patients with normal preoperative LVEF treated with VA-ECMO for coronary malperfusion-related PCCS between May 1998 and May 2018. The primary outcome was 30-day mortality, which was compared using the Kaplan-Meier method and the log-rank test. Multivariable logistic regression was performed to identify predictors of mortality. RESULTS: During the study period, a total of 62,125 patients underwent cardiac surgery at our institution. Amongst them, 59 patients (0.1%) with normal preoperative LVEF required VA-ECMO support due to coronary malperfusion-related PCCS. The mean duration of VA-ECMO support was 6 days (interquartile range 4-7 days). The 30-day mortality was 50.8%. Under VA-ECMO therapy, a complication composite outcome of bleeding, re-exploration for bleeding, acute renal failure, acute liver failure, and sepsis occurred in 51 (86.4%) patients. Independent predictors of 30-day mortality were lactate levels > 9.9 mmol/l before VA-ECMO implantation (odds ratio [OR]: 3.3; 95% confidence interval [CI] 1.5-7.0; p = 0.002), delay until revascularization > 278 minutes (OR: 2.9; 95% CI 1.3-6.4; p = 0.008) and peripheral arterial artery disease (OR: 3.3; 95% 1.6-7.5; p = 0.001). CONCLUSIONS: Mortality rates are high in patients with normal preoperative LVEF who develop PCCS due to coronary malperfusion. The early implantation of VA-ECMO before the development of profound tissue hypoxia and early coronary revascularization increases the likelihood of survival. Lactate levels are useful to define optimal timing for the VA-ECMO initiation.

BACKGROUND/PURPOSE: Acute kidney injury (AKI) after transcatheter aortic valve implantation (TAVI) increases morbidity and mortality. Our study aimed to investigate the role of baseline N-terminal pro B-type natriuretic peptide (NT-proBNP) as a predictor of AKI following TAVI. METHODS: All consecutive TAVI patients were included in the analysis, except patients with dialysis and those with a GFR < 15 ml/min/1.73 m2 at baseline. Rates of AKI after TAVI were assessed according to the updated valve academic research consortium definitions using AKIN classification in three stages. NT-proBNP was measured at baseline. One-year mortality rates were assessed. RESULTS: We included 1973 patients treated with TAVI between January 2006 and December 2016. Median [IQR] age was 81.0 [77.0;84.0] years, the STS score was 6.2 [3.9;9.0], and the logEuroScore was 14.5 [9.0;23.0]. 30-day and one-year mortality was 5.1 % and 16.1 % for all patients, respectively. Multivariate analysis revealed that patients with NT-proBNP levels higher than two times above the upper level of normal (ULN) had an increased risk for AKI after TAVI compared to patients with NT-proBNP levels < 2× ULN (OR 1.40 [1.03-1.91]). CONCLUSIONS: Routine assessment of baseline NT-proBNP levels might be an additional tool to identify patients at increased risk for AKI after TAVI.
RESUMEN
OBJECTIVES: In this study, we evaluated if modified Del Nido cardioplegia delivers comparable cardiac protection in comparison to Custodiol® in patients undergoing isolated minimally invasive mitral valve repair. METHODS: From January 2018 to October 2021, all patients undergoing non-emergent isolated minimally invasive mitral valve repair were included in this study. The cardioplegia was chosen at the surgeons' discretion. The primary end points of this study were peak postoperative cardiac enzyme levels. Secondary end points were in-hospital mortality, hospital stay, occurrence of cardiac arrhythmias, pacemaker implantations, postoperative lactate and sodium levels and postoperative incidence of renal failure requiring dialysis. RESULTS: A total of 355 patients were included in this study. The mean age of patients was 57. After propensity score matching, a total of 156 pairs were identified. There was no difference in cross-clamp time between both groups. Postoperative creatine kinase levels were higher in patients receiving Custodiol on the 1st and 2nd postoperative days. Creatine kinase isoenzyme MB levels were higher in patients receiving Custodiol on the 2nd postoperative day (0.5 ± 0.2 vs 0.4 ± 0.1 µmol/l s; P < 0.001). Postoperative Troponin T concentrations were similar between both groups. Maximum lactate concentrations were higher in patients receiving Custodiol on the day of surgery (2.4 ± 1.9 vs 2.0 ± 1.1 mmol/l; P = 0.04). The overall hospital stay was longer in patients receiving Del Nido cardioplegia (10.6 ± 3.2 vs 8 ± 4.1 days; P < 0.01). CONCLUSIONS: Modified Del Nido cardioplegia based on Ionosteril® solution offers equivalent protection compared to Custodiol for isolated minimally invasive mitral valve repair.

OBJECTIVES: The frequency of minimally invasive mitral valve surgery (MVS) has steadily increased over the last decades and therefore surgeons are now encountering an increasing number of patients requiring mitral valve (MV) reoperations post-minimally invasive MVS. The aim of this study was to analyse the early postoperative outcomes and the long-term survival in patients who undergo reoperative MVS following previous minimally invasive surgery. METHODS: Patients who underwent redo MVS following prior minimally invasive MVS between January 2002 and December 2021 were included in our analysis. Study data were prospectively collected and retrospectively analysed. The primary outcomes were 30-day mortality and long-term survival. RESULTS: Among the 187 included patients, 34 (18.2%) underwent repeat MV repair and 153 (81.8%) MV replacement. The median age was 66 years (interquartile range 56-74) and 80 (42.8%) patients were female. Redo MVS was performed through median sternotomy in 169 patients (90.4%). A total of 77 (41.2%) patients had additional concomitant procedures. The median intensive care unit stay was 1 day (1-5). The 30-day mortality was 6.4% (12/187). Estimated survival at 5 and 12 years was 61.8% and 38.3%, respectively. Preoperative stroke (hazard ratio 3.28, 95% confidence interval 1.37-7.85, P = 0.007) as well as infective endocarditis (hazard ratio 1.85; 95% confidence interval 1.09-3.11, P = 0.021) were independent predictors of long-term mortality. CONCLUSIONS: Redo MVS following prior minimally invasive MVS can be performed safely with low early perioperative mortality and acceptable long-term survival. Preoperative stroke, infective endocarditis and concomitant tricuspid valve surgery are independent predictors of long-term mortality.
RESUMEN
BACKGROUND: This study investigated the safety and effectiveness of surgical aortic valve replacement with RESILIA tissue (Edwards Lifesciences) through 5 years in patients with native bicuspid aortic valves. Outcomes were compared with those for patients with tricuspid aortic valves. METHODS: Of 689 patients from the COMMENCE (ProspeCtive, nOn-randoMized, MulticENter) trial who received the study valve, 645 had documented native valve morphology and core laboratory-evaluable echocardiograms from any postoperative visit, which were used to model hemodynamic outcomes over 5 years. Linear mixed-effects models were used to estimate longitudinal changes in mean gradient and effective orifice area. RESULTS: Patients with native bicuspid aortic valves (n = 214) were more than a decade younger than those with tricuspid aortic valves (n = 458; 59.8 ± 12.4 years vs 70.2 ± 9.5 years; P < .001). The bicuspid aortic valve cohort exhibited no structural valve deterioration over 5 years, and rates of paravalvular leak and transvalvular regurgitation were low (0.7% and 2.9%, respectively [all mild] at 5 years). These outcomes mirrored those in patients with native tricuspid aortic valves. The model-estimated postoperative mean gradient and effective orifice area, as well as the rate of change of these outcomes, adjusted for age, body surface area, and bioprosthesis size, did not differ between the 2 cohorts. CONCLUSIONS: Among patients with bicuspid aortic valves, RESILIA tissue valves demonstrated excellent outcomes to 5 years, including no structural valve deterioration and very low rates of paravalvular and transvalvular regurgitation. These results are encouraging for RESILIA tissue durability in young patients.

BACKGROUND: Degenerative mitral regurgitation is associated with heart failure, arrhythmia, and mortality. The impact of sex on timing of surgical referral and outcomes has not been reported comprehensively. We examined preoperative status and surgical outcomes of male versus female DMR patients undergoing surgery. METHODS: We reviewed our institutional database for all patients undergoing surgery for degenerative mitral regurgitation between 2013 and 2021. Preoperative clinical and echocardiographic variables, surgical characteristics, and outcomes were compared; and left atrial strain in available images. RESULTS: Of 963 patients, 314 (32.6%) were female. Women were older (67 vs. 64 years, p = 0.031) and more often had bileaflet prolapse (19.4% vs. 13.8%, p = 0.028), mitral annular calcification (12.1% vs. 5.4%, p < 0.001) and tricuspid regurgitation (TR; 31.8% vs. 22.5%, p = 0.001). Indexed left ventricular end-diastolic and end-systolic diameters were higher in women, with 29.4 vs. 26.7 mm/m2 (p < 0.001) and 18.2 vs. 17 mm/m2 (p < 0.001), respectively, and left atrial conduit strain lower (17.6% vs, 21.2%, p = 0.001). Predicted risk of mortality was 0.73% vs. 0.54% in men (p = 0.023). Women required mechanical circulatory support more frequently (1.3% vs 0%, p = 0.011), had longer intensive care unit stay (29 vs. 26 hours, p < 0.001), mechanical ventilation (5.4 vs. 5 hours, p = 0.036), and overall hospitalization (7 vs. 6 days, p < 0.001). There was no difference in long-term re-operation-free survival (p = 0.35). CONCLUSIONS: Women undergoing mitral valve repair are older and show indicators of more advanced disease with long-standing left ventricular impairment. Guidelines may need to be adjusted and address this disparity, to improve postoperative recovery times and outcomes.
RESUMEN
OBJECTIVES: To date, there are no standardized treatment algorithms or recommendations for patients with infective endocarditis (IE) and concomitant spondylodiscitis (SD). Therefore, our aim was to analyse whether the sequence of surgical treatment of IE and SD has an impact on postoperative outcome and to identify risk factors for survival and postoperative recurrence. METHODS: Patients with IE underwent surgery in 4 German university hospitals between 1994 and 2022. Univariable and multivariable analyses were performed to identify possible predictors of 30-day/1-year mortality and recurrence of IE and/or SD. RESULTS: From the total IE cohort (n = 3991), 150 patients (4.4%) had concomitant SD. Primary surgery for IE was performed in 76.6%, and primary surgery for SD in 23.3%. The median age was 70.0 (64.0-75.6) years and patients were mostly male (79.5%). The most common pathogens detected were enterococci and Staphylococcus aureus followed by streptococci, and coagulase-negative Staphylococci. If SD was operated on first, 30-day mortality was significantly higher than if IE was operated on 1st (25.7% vs 11.4%; P = 0.037) and we observed a tendency for a higher 1-year mortality. If IE was treated 1st, we observed a higher recurrence rate within 1 year (12.2% vs 0%; P = 0.023). Multivariable analysis showed that primary surgery for SD was an independent predictor of 30-day mortality. CONCLUSIONS: Primary surgical treatment for SD was an independent risk factor for 30-day mortality. When IE was treated surgically 1st, the recurrence rate of IE and/or SD was higher.

OBJECTIVES: The aim of this multicentre study was to demonstrate the safety and clinical performance of E-vita OPEN NEO Stent Graft System (Artivion, Inc.) in the treatment of aneurysm or dissection, both acute and chronic, in the ascending aorta, aortic arch and descending thoracic aorta. METHODS: In this observational study of 12 centres performed in Europe and in Asia patients were enrolled between December 2020 and March 2022. All patients underwent frozen elephant trunk using E-vita OPEN NEO Stent Graft System. Primary end point was the rate of all-cause mortality at 30 days and secondary end points included further clinical and safety data are reported up to 3-6 months postoperatively. RESULTS: A total of 100 patients (66.7% male; mean age, 57.7 years) were enrolled at 12 sites. A total of 99 patients underwent surgery using the E-vita OPEN NEO for acute or subacute type A aortic dissection (n = 37), chronic type A aortic dissection (n = 33) or thoracic aortic aneurysm (n = 29), while 1 patient did not undergo surgery. Device technical success at 24 h was achieved in 97.0%. At discharge, new disabling stroke occurred in 4.4%, while new paraplegia and new paraparesis was reported in 2.2% and 2.2%, respectively. Renal failure requiring permanent (>90 days) dialysis or hemofiltration at discharge was observed in 3.3% of patients. Between discharge and the 3-6 months visit, no patients experienced new disabling stroke, new paraplegia or new paraparesis. The 30-day mortality was 5.1% and the estimated 6-month survival rate was 91.6% (standard deviation: 2.9). CONCLUSIONS: Total arch replacement with the E-vita OPEN NEO can be performed with excellent results in both the acute and chronic setting. This indicates that E-vita OPEN NEO can be used safely, including in the setting of acute type A aortic dissection.

Importance: The use of valve-in-valve (ViV) transcatheter aortic valve replacement (TAVR) has been rapidly expanding as an alternative treatment to redo surgical aortic valve replacement (SAVR) for failed bioprosthetic valves despite limited long-term data. Objective: To assess mortality and morbidity in patients undergoing intervention for failed bioprosthetic SAVR. Design, Setting, and Participants: This was a retrospective population-based cohort analysis conducted between January 1, 2015, and December 31, 2020, with a median (IQR) follow-up time of 2.3 (1.1-4.0) years. A total of 1771 patients with a history of bioprosthetic SAVR who underwent ViV-TAVR or redo SAVR in California, New York, and New Jersey were included. Data were obtained from the California Department of Health Care Access and Information, the New York Statewide Planning and Research Cooperative System, and the New Jersey Discharge Data Collection System. Exclusion criteria included undergoing TAVR or redo SAVR within 5 years from initial SAVR, as well as infective endocarditis, concomitant surgical procedures, and out-of-state residency. Propensity matching yielded 375 patient pairs. Data were analyzed from January to December 2023. Interventions: ViV-TAVR vs redo SAVR. Main Outcomes and Measurements: The primary outcome was all-cause mortality. Secondary outcomes were stroke, heart failure hospitalization, reoperation, major bleeding, acute kidney failure, new pacemaker insertion, and infective endocarditis. Results: From 2015 through 2020, the proportion of patients undergoing ViV-TAVR vs redo SAVR increased from 159 of 451 (35.3%) to 498 or 797 (62.5%). Of 1771 participants, 653 (36.9%) were female, and the mean (SD) age was 74.4 (11.3) years. Periprocedural mortality and stroke rates were similar between propensity-matched groups. The ViV-TAVR group had lower periprocedural rates of major bleeding (2.4% vs 5.1%; P = .05), acute kidney failure (1.3% vs 7.2%; P < .001), and new pacemaker implantations (3.5% vs 10.9%; P < .001). The 5-year all-cause mortality rate was 23.4% (95% CI, 15.7-34.1) in the ViV-TAVR group and 13.3% (95% CI, 9.2-18.9) in the redo SAVR group. In a landmark analysis, no difference in mortality was observed up to 2 years (hazard ratio, 1.03; 95% CI, 0.59-1.78), but after 2 years, ViV-TAVR was associated with higher mortality (hazard ratio, 2.97; 95% CI, 1.18-7.47) as well as with a higher incidence of heart failure hospitalization (hazard ratio, 3.81; 95% CI, 1.57-9.22). There were no differences in 5-year incidence of stroke, reoperation, major bleeding, or infective endocarditis. Conclusions and Relevance: Compared with redo SAVR, ViV-TAVR was associated with a lower incidence of periprocedural complications and a similar incidence of all-cause mortality through 2 years' follow-up. However, ViV-TAVR was associated with higher rates of late mortality and heart failure hospitalization. These findings may be influenced by residual confounding and require adjudication in a randomized clinical trial.

OBJECTIVES: This study aimed to analyse the impact of preoperative septic cerebral embolism on early and late postoperative outcomes in patients with infective endocarditis undergoing valve surgery. METHODS: Retrospective multicentric study based on the Clinical Multicentric Project for Analysis of Infective Endocarditis in Germany (CAMPAIGN) registry comprising patients with infective endocarditis who underwent valve surgery between 1994 and 2018 at 6 German centres. Patients were divided into 2 groups for statistical comparison according to the presence or absence of preoperative septic cerebral embolism. Propensity score matching was performed for adjusted comparisons of postoperative outcomes. Primary outcomes were 30-day mortality and estimated 5-year survival. RESULTS: A total of 4917 patients were included in the analysis, 3909 (79.5%) patients without and 1008 (20.5%) patients with preoperative septic cerebral embolism. Patients with preoperative septic cerebral embolism had more baseline comorbidities. Mitral valve endocarditis (44.1% vs 33.0% P < 0.001), large vegetations >10 mm (43.1% vs 30.0%, P < 0.001), and Staphylococcus species infection (42.3% vs 21.3%, P < 0.001) were more frequent in the cerebral embolism group. Among patients with preoperative cerebral embolism, 286 (28.4%) patients had no stroke signs (silent stroke). After matching (1008 matched pairs), there was no statistically significant difference in 30-day mortality (20.1% vs 22.8%; P = 0.14) and 5-year survival (47.8% vs 49.1%; stratified log-rank P = 0.77) in patients with and without preoperative cerebral embolism, respectively. CONCLUSIONS: Preoperative septic cerebral embolism in patients with infective endocarditis requiring valve surgery does not negatively affect early or late mortality; therefore, it should not play a major role in deciding if surgery is to be performed.

OBJECTIVES: Patients with diabetes mellitus (DM) undergoing coronary artery bypass grafting (CABG) have been repeatedly demonstrated to have worse clinical outcomes compared to patients without DM. The objective of this study was to evaluate the impact of DM on 1-year clinical outcomes after isolated CABG. METHODS: The European DuraGraft registry included 1130 patients (44.6%) with and 1402 (55.4%) patients without DM undergoing isolated CABG. Intra-operatively, all free venous and arterial grafts were treated with an endothelial damage inhibitor. Primary end point in this analysis was the incidence of a major adverse cardiac event (MACE), a composite of all-cause death, repeat revascularization or myocardial infarction at 1 year post-CABG. To balance between differences in baseline characteristics (n = 1072 patients in each group), propensity score matching was used. Multivariable Cox proportional hazards regression was performed to identify independent predictors of MACE. RESULTS: Diabetic patients had a higher cardiovascular risk profile and EuroSCORE II with overall more comorbidities. Patients were comparable in regard to surgical techniques and completeness of revascularization. At 1 year, diabetics had a higher MACE rate {7.9% vs 5.5%, hazard ratio (HR) 1.43 [95% confidence interval (CI) 1.05-1.95], P = 0.02}, driven by increased rates of death [5.6% vs 3.5%, HR 1.61 (95% CI 1.10-2.36), P = 0.01] and myocardial infarction [2.8% vs 1.4%, HR 1.99 (95% CI 1.12-3.53) P = 0.02]. Following propensity matching, no statistically significant difference was found for MACE [7.1% vs 5.7%, HR 1.23 (95% CI 0.87-1.74) P = 0.23] or its components. Age, critical operative state, extracardiac arteriopathy, ejection fraction ≤50% and left main disease but not DM were identified as independent predictors for MACE. CONCLUSIONS: In this study, 1-year outcomes in diabetics undergoing isolated CABG were comparable to patients without DM.
RESUMEN
OBJECTIVES: Sex-related differences play a role in cardiovascular disease-related outcomes. There is, however, a knowledge gap regarding sex-specific differences in patients with infective endocarditis (IE)-requiring surgical treatment. This study aims to analyse sex-related differences in the clinical presentation, treatment and clinical outcomes of patients with IE-requiring surgical treatment from the multicentric Germany-wide CAMPAIGN registry. METHODS: Patients with IE who underwent cardiac surgery between 1994 and 2018 at six German centres were retrospectively analysed. Outcomes were compared based on patients' sex. Primary outcomes were 30-day mortality and mid-term survival. RESULTS: A total of 4917 patients were included in the analysis (1364 female [27.7%] and 3553 male [72.3%]). Female patients presented with more comorbidities and higher surgical risk (EuroScore II 12.0% vs 10.0%, P < 0.001). The early postoperative course of female patients was characterized by longer ventilation times (20.0 h vs 16.0 h; P = 0.004), longer intensive care unit stay (4.0 days vs 3.0 days; P < 0.001), and more frequent new-onset dialysis (265 [20.3%] vs 549 [16.3%]; P = 0.001). The 30-day mortality was 13.8% and 15.5% in female and male patients, respectively (P = 0.06). The estimated mid-term survival was significantly higher amongst male patients (56.1% vs 45.4%; Log-rank P < 0.001). Female sex was an independent predictor of mid-term mortality (HR 1.2 [95% CI 1.0-1.4], P = 0.01). CONCLUSIONS: Male patients more frequently undergo cardiac surgery for IE. However, female patients have a higher surgical risk profile and subsequently an increased early postoperative morbidity, but with similar 30-day mortality compared with male patients. The estimated mid-term survival is lower amongst female patients.

RESUMEN
OBJECTIVES: The aim of this study was to analyse the indications, surgical extent and results of treatment, as well as determine the risk factors for adverse outcomes after redo arch surgery. METHODS: Between January 1996 and December 2022, 120 patients underwent aortic arch reoperations after primary proximal aortic surgery. We retrospectively analysed perioperative data, as well as early and mid-term outcomes in these patients. RESULTS: Indications for arch reintervention included new aortic aneurysm in 34 patients (28.3%), expanding post-dissection aneurysm in 36 (30.0%), aortic graft infection in 39 (32.5%) and new aortic dissection in 9 cases. Two patients underwent reoperation due to iatrogenic complications. Thirty-one patients (25.8%) had concomitant endocarditis. In-hospital and 30-day mortality rates were 11.7% and 15.0%, respectively. Stroke was observed in 11 (9.2%) and paraplegia in 1 patient. Prior surgery due to aneurysm [odds ratio 4.5; 95% confidence interval (CI) 1.4-17.3] and critical preoperative state (odds ratio 5.9; 95% CI 1.5-23.7) were independent predictors of 30-day mortality. Overall 1- and 5-year survival was 65.8 ± 8.8% and 51.2 ± 10.6%, respectively. Diabetes mellitus (hazard ratio 2.4; 95% CI 1.0-5.1) and peripheral arterial disease (hazard ratio 4.7; 95% CI 1.1-14.3) were independent predictors of late death. The cumulative incidence of reoperations was 12.6% (95% CI 6.7-20.4%) at 5 years. Accounting for mortality as a competing event, connective tissue disorders (subdistribution hazard ratio 4.5; 95% CI 1.6-15.7) and interval between primary and redo surgery (subdistribution hazard ratio 1.04; 95% CI 1.02-1.06) were independent predictors of reoperations after redo arch surgery. CONCLUSIONS: Despite being technically demanding, aortic arch reoperations are feasible and can be performed with acceptable results.

Objective: To compare machine learning (ML)-based CT-derived fractional flow reserve (CT-FFR) in patients before transcatheter aortic valve replacement (TAVR) by observers with differing training and to assess influencing factors. Background: Coronary computed tomography angiography (cCTA) can effectively exclude CAD, e.g. prior to TAVR, but remains limited by its specificity. CT-FFR may mitigate this limitation also in patients prior to TAVR. While a high reliability of CT-FFR is presumed, little is known about the reproducibility of ML-based CT-FFR. Methods: Consecutive patients with obstructive CAD on cCTA were evaluated with ML-based CT-FFR by two observers. Categorization into hemodynamically significant CAD was compared against invasive coronary angiography. The influence of image quality and coronary artery calcium score (CAC) was examined. Results: CT-FFR was successfully performed on 214/272 examinations by both observers. The median difference of CT-FFR between both observers was -0.05(-0.12-0.02) (p < 0.001). Differences showed an inverse correlation to the absolute CT-FFR values. Categorization into CAD was different in 37/214 examinations, resulting in net recategorization of Δ13 (13/214) examinations and a difference in accuracy of Δ6.1%. On patient level, correlation of absolute and categorized values was substantial (0.567 and 0.570, p < 0.001). Categorization into CAD showed no correlation to image quality or CAC (p > 0.13). Conclusion: Differences between CT-FFR values increased in values below the cut-off, having little clinical impact. Categorization into CAD differed in several patients, but ultimately only had a moderate influence on diagnostic accuracy. This was independent of image quality or CAC.
