VARC-3 defined outcome of valve-in-valve transcatheter aortic valve implantation in stentless compared with stented aortic bioprostheses.

BACKGROUND: Valve-in-valve (ViV) transcatheter aortic valve implantation (TAVI) is a viable alternative to redo surgery in selected patients with bioprosthetic valve dysfunction. Most ViV-TAVI procedures have been performed in stented bioprosthetic valves (ST); stentless bioprostheses (SL) lack fluoroscopic markers and could be more challenging for ViV-TAVI. Data on more recent patients applying Valve Academic Research Consortium (VARC)-3 defined outcomes are scarce. We compared patient characteristics, procedural outcomes, and 5-year mortality of patients with SL versus ST aortic bioprosthetic valve failure undergoing ViV-TAVI. METHODS: Patients undergoing ViV-TAVI between 2007 and 2022 (52.5% of cases after 2015) at 3 German centers were included in this analysis. The co-primary outcome measures were technical success, device success, and early safety defined by VARC-3. Mortality was assessed up to 5 years. RESULTS: Overall, 43 (11.8%) SL and 313 (88.2%) ST ViV-TAVI were included. Patients were comparable with regard to age, sex, clinically relevant baseline comorbidities, and surgical risk. Technical success (SL: 83.7% versus ST: 79.9%, p = 0.552), device success (SL: 67.4% versus ST: 54.3%, p = 0.105), and early safety (SL: 74.4% versus ST: 66.5%, p = 0.296) were comparable between groups. The 30-day mortality (SL: 7.0% versus ST: 2.6%, p = 0.136) and 5-year mortality rates (SL: 23.3% versus ST: 24.6%, p = 0.874) were not significantly different between groups. CONCLUSION: SL and ST ViV-TAVI led to comparable short-term outcomes according to VARC-3- defined endpoints and similar mortality rates up to 5 years of follow-up. VARC-3 defined technical success, device success, and early safety as well as 5-year all-cause mortality in patients undergoing valve-in-valve transcatheter aortic valve implantation (ViV-TAVI) into stentless (SL) compared with stented (ST) failed aortic bioprostheses.

Impact of Enterococci vs. Staphylococci Induced Infective Endocarditis after Transcatheter Aortic Valve Implantation.

BACKGROUND: The two most common organisms found in infective endocarditis following transcatheter aortic valve implantation (TAVI-IE) are enterococci (EC-IE) and staphylococci (SC-IE). We aimed to compare clinical characteristics and outcomes of patients with EC-IE and SC-IE. METHODS: TAVI-IE patients from 2007 to 2021 were included in this analysis. The 1-year mortality was the primary outcome measure of this retrospective multi-center analysis. RESULTS: Out of 163 patients, 53 (32.5%) EC-IE and 69 (42.3%) SC-IE patients were included. Subjects were comparable with regard to age, sex, and clinically relevant baseline comorbidities. Symptoms at admission were not significantly different between groups, except for a lower risk for presenting with septic shock in EC-IE than SC-IE. Treatment was performed in 78% by antibiotics alone and in 22% of patients by surgery and antibiotics, with no significant differences between groups. The rate of any complication, in particular heart failure, renal failure, and septic shock during treatment for IE, was lower in EC-IE compared with SC-IE (p < 0.05). In-hospital (EC-IE: 36% vs. SC-IE: 56%, p = 0.035) and 1-year mortality (EC-IE: 51% vs. SC-IE: 70%, p = 0.009) were significantly lower in EC-IE compared with SC-IE. CONCLUSIONS: EC-IE, compared with SC-IE, was associated with a lower morbidity and mortality. However, absolute numbers are high, a finding that should trigger further research in appropriate perioperative antibiotic management and improvement of early IE diagnosis in the case of clinical suspicion.

Incidence, Clinical Characteristics, and Impact of Absent Echocardiographic Signs in Patients With Infective Endocarditis After Transcatheter Aortic Valve Implantation.

BACKGROUND: Echocardiography is the primary imaging modality for diagnosis of infective endocarditis (IE) in prosthetic valve endocarditis (PVE) including IE after transcatheter aortic valve implantation (TAVI). This study aimed to evaluate the characteristics and clinical outcomes of patients with absent compared with evident echocardiographic signs of TAVI-IE. METHODS: Patients with definite TAVI-IE derived from the Infectious Endocarditis after TAVI International Registry were investigated comparing those with absent and evident echocardiographic signs of IE defined as vegetation, abscess, pseudo-aneurysm, intracardiac fistula, or valvular perforation or aneurysm. RESULTS: Among 578 patients, 87 (15.1%) and 491 (84.9%) had absent (IE-neg) and evident (IE-pos) echocardiographic signs of IE, respectively. IE-neg were more often treated via a transfemoral access with a self-expanding device and had higher rates of peri-interventional complications (eg, stroke, major vascular complications) during the TAVI procedure (P < .05 for all). IE-neg had higher rates of IE caused by Staphylococcus aureus (33.7% vs 23.2%; P = .038) and enterococci (37.2% vs 23.8%; P = .009) but lower rates of coagulase-negative staphylococci (4.7% vs 20.0%, P = .001). IE-neg was associated with the same dismal prognosis for in-hospital mortality in a multivariate binary regression analysis (odds ratio: 1.51; 95% confidence interval [CI]: .55-4.12) as well as a for 1-year mortality in Cox regression analysis (hazard ratio: 1.10; 95% CI: .67-1.80). CONCLUSIONS: Even with negative echocardiographic imaging, patients who have undergone TAVI and presenting with positive blood cultures and symptoms of infection are a high-risk patient group having a reasonable suspicion of IE and the need for an early treatment initiation.

Continued non-vitamin K antagonist oral anticoagulants versus vitamin K antagonists during transcatheter aortic valve implantation.

BACKGROUND: One-third of patients undergoing transcatheter aortic valve implantation (TAVI) have an indication for long-term oral anticoagulation (OAC). AIMS: We aimed to investigate whether continued non-vitamin K antagonist oral anticoagulant (NOAC) therapy compared with continued vitamin K antagonist (VKA) therapy during TAVI is equally safe and effective.  Methods: Consecutive patients on OAC with either NOAC or VKA undergoing transfemoral TAVI at five European centres were enrolled. The primary outcome measure was a composite of major/life-threatening bleeding, stroke, and all-cause mortality at 30 days. RESULTS: In total, 584 patients underwent TAVI under continued OAC with 294 (50.3%) patients receiving VKA and 290 (49.7%) patients receiving NOAC. At 30 days, the composite primary outcome had occurred in 51 (17.3%) versus 36 (12.4%) patients with continued VKA and with continued NOAC, respectively (odds ratio [OR] 0.68, 95% confidence interval [CI]: 0.43-1.07; p=0.092). Rates of major/life-threatening bleeding (OR 0.87, 95% CI: 0.52-1.47; p=0.606) and stroke (OR 1.02, 95% CI: 0.29-3.59; p=0.974) were not different between groups. In a multivariate Cox regression analysis, continued NOAC, compared with continued VKA, was associated with a lower risk for all-cause 1-year mortality (hazard ratio [HR] 0.61, 95% CI: 0.37-0.98; p=0.043). The analysis of the propensity score-matched cohort revealed similar results. CONCLUSIONS: Continued NOAC compared with continued VKA during TAVI led to comparable outcomes with regard to the composite outcome measure indicating that continued OAC with both drugs is feasible. These hypothesis-generating results need to be confirmed by a dedicated randomised controlled trial.

Sex Differences in Infective Endocarditis After Transcatheter Aortic Valve Replacement.

BACKGROUND: Outcomes after transcatheter aortic valve replacement (TAVR) and infectious diseases may vary according to sex. METHODS: This multicentre study aimed to determine the sex differences in clinical characteristics, management, and outcomes of infective endocarditis (IE) after TAVR. A total of 579 patients (217 women, 37.5%) who had the diagnosis of definite IE following TAVR were included retrospectively from the Infectious Endocarditis After TAVR International Registry. RESULTS: Women were older (80 ± 8 vs 78 ± 8 years; P = 0.001) and exhibited a lower comorbidity burden. Clinical characteristics and microbiological profiles were similar between men and women, but culture-negative IE was more frequent in women (9.9% vs 4.3%; P = 0.009). A high proportion of patients had a clinical indication for surgery (54.4% in both groups; P = 0.99), but a surgical intervention was performed in a minority of patients (women 15.2%, men 20.3%; P = 0.13). The mortality rate at index IE hospitalisation was similar in both groups (women 35.4%, men 31.7%; P = 0.37), but women exhibited a higher mortality rate at 2-year follow-up (63% vs 52.1%; P = 0.021). Female sex remained an independent risk factor for cumulative mortality in the multivariable analysis (adjusted HR 1.28, 95% CI 1.02-1.62; P = 0.035). After adjustment for in-hospital events, surgery was not associated with better outcomes in women. CONCLUSIONS: There were no significant sex-related differences in the clinical characteristics and management of IE after TAVR. However, female sex was associated with increased 2-year mortality risk.

Very early infective endocarditis after transcatheter aortic valve replacement.

BACKGROUND: Scarce data exist about early infective endocarditis (IE) after trans-catheter aortic valve replacement (TAVR). OBJECTIVE: The objective was to evaluate the characteristics, management, and outcomes of very early (VE) IE (≤ 30 days) after TAVR. METHODS: This multicenter study included a total of 579 patients from the Infectious Endocarditis after TAVR International Registry who had the diagnosis of definite IE following TAVR. RESULTS: Ninety-one patients (15.7%) had VE-IE. Factors associated with VE-IE (vs. delayed IE (D-IE)) were female gender (p = 0.047), the use of self-expanding valves (p < 0.001), stroke (p = 0.019), and sepsis (p < 0.001) after TAVR. Staphylococcus aureus was the main pathogen among VE-IE patients (35.2% vs. 22.7% in the D-IE group, p = 0.012), and 31.2% of Staphylococcus aureus infections in the VE-IE group were methicillin-resistant (vs. 14.3% in the D-IE group, p = 0.001). The second-most common germ was enterococci (34.1% vs. 24.4% in D-IE cases, p = 0.05). VE-IE was associated with very high in-hospital (44%) and 1-year (54%) mortality rates. Acute renal failure following TAVR (p = 0.001) and the presence of a non-enterococci pathogen (p < 0.001) were associated with an increased risk of death. CONCLUSION: A significant proportion of IE episodes following TAVR occurs within a few weeks following the procedure and are associated with dismal outcomes. Some baseline and TAVR procedural factors were associated with VE-IE, and Staphylococcus aureus and enterococci were the main causative pathogens. These results may help to select the more appropriate antibiotic prophylaxis in TAVR procedures and guide the initial antibiotic therapy in those cases with a clinical suspicion of IE. Very early infective endocarditis after trans-catheter aortic valve replacement. VE-IE indicates very early infective endocarditis (≤30 days post TAVR). D-IE indicates delayed infective endocarditis.

Surgical Treatment of Patients With Infective Endocarditis After Transcatheter Aortic Valve Implantation.

BACKGROUND: The optimal treatment of patients developing infective endocarditis (IE) after transcatheter aortic valve implantation (TAVI) is uncertain. OBJECTIVES: The goal of this study was to investigate the clinical characteristics and outcomes of patients with TAVI-IE treated with cardiac surgery and antibiotics (IE-CS) compared with patients treated with antibiotics alone (IE-AB). METHODS: Crude and inverse probability of treatment weighting analyses were applied for the treatment effect of cardiac surgery vs medical therapy on 1-year all-cause mortality in patients with definite TAVI-IE. The study used data from the Infectious Endocarditis after TAVI International Registry. RESULTS: Among 584 patients, 111 patients (19%) were treated with IE-CS and 473 patients (81%) with IE-AB. Compared with IE-AB, IE-CS was not associated with a lower in-hospital mortality (HRunadj: 0.85; 95% CI: 0.58-1.25) and 1-year all-cause mortality (HRunadj: 0.88; 95% CI: 0.64-1.22) in the crude cohort. After adjusting for selection and immortal time bias, IE-CS compared with IE-AB was also not associated with lower mortality rates for in-hospital mortality (HRadj: 0.92; 95% CI: 0.80-1.05) and 1-year all-cause mortality (HRadj: 0.95; 95% CI: 0.84-1.07). Results remained similar when patients with and without TAVI prosthesis involvement were analyzed separately. Predictors for in-hospital and 1-year all-cause mortality included logistic EuroSCORE I, Staphylococcus aureus, acute renal failure, persistent bacteremia, and septic shock. CONCLUSIONS: In this registry, the majority of patients with TAVI-IE were treated with antibiotics alone. Cardiac surgery was not associated with an improved all-cause in-hospital or 1-year mortality. The high mortality of patients with TAVI-IE was strongly linked to patients' characteristics, pathogen, and IE-related complications.

Manta versus Perclose ProGlide vascular closure device after transcatheter aortic valve implantation: Initial experience from a large European center.

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.

Left-Atrial Appendage Thrombosis in Patients With Severe Aortic Stenosis Undergoing Transcatheter Aortic Valve Implantation.

BACKGROUND: Data about the impact of left-atrial appendage thrombosis (LAAT) on early safety and mortality in patients undergoing transfemoral transcatheter aortic valve implantation (TF-TAVI) are scarce. We aimed to investigate the prevalence and predictors of LAAT and the outcome associated with this condition in patients treated by TF-TAVI. METHODS: Retrospective data analysis was derived from a prospective single-centre registry comparing patients with and without LAAT regarding early safety at 30 days, according to Valve Academic Research Consortium-2 (VARC-2) and 2-year mortality. RESULTS: LAAT was found in 7.6% of the whole cohort (n = 2527) and in 16.6% in those patients with known pre-existing atrial fibrillation (AF cohort, n = 1099). Compared with controls, patients with LAAT were sicker, indicated by a higher Society of Thoracic Surgeons (STS) score and burden of comorbidities. Neither VARC-2-defined early safety at 30 days nor the rate of stroke was different between LAAT and controls in both the whole (early safety: 29.2% vs 24.2%, P = 0.123; stroke: 5.9% vs 4.7%, P = 0.495) and AF cohort (early safety: 29.1% vs 22.9%, P = 0.072; stroke: 5.6% vs 3.3%, P = 0.142). Evaluating the whole cohort in a univariate analysis, the 2-year mortality was significantly higher in LAAT compared with controls (hazard ratio, 1.41; 95% confidence interval, 1.07-1.86; P = 0.014). However, multivariate analysis of the whole cohort and the AF cohort revealed no association between LAAT and 2-year mortality. CONCLUSIONS: LAAT was frequent in patients undergoing TF-TAVI- in particular, in patients with histories of AF-but it was not associated with an increase in periprocedural complications and did not predict 2-year mortality.

Safety and Efficacy of Transcatheter Aortic Valve Replacement With Continuation of Vitamin K Antagonists or Direct Oral Anticoagulants.

OBJECTIVES: This study investigated whether transcatheter aortic valve replacement (TAVR) with peri-procedural continuation of oral anticoagulation is equally safe and efficacious as TAVR with peri-procedural interruption of anticoagulation. BACKGROUND: A significant proportion of patients undergoing TAVR have an indication for long-term oral anticoagulation. The optimal peri-procedural management of such patients is unknown. METHODS: Consecutive patients on oral anticoagulation who underwent transfemoral TAVR at 5 European centers were enrolled. Oral anticoagulation was either stopped 2 to 4 days before TAVR or continued throughout the procedure. Primary safety outcome was major bleeding. Secondary efficacy endpoints included vascular complications, stroke, and mortality. RESULTS: Of 4,459 patients, 584 patients were treated with continuation of anticoagulation and 733 with interruption of anticoagulation. At 30 days, major or life-threatening bleedings occurred in 66 (11.3%) versus 105 (14.3%; odds ratio [OR]: 0.86; 95% confidence interval [CI]: 0.61 to 1.21; p = 0.39) and major vascular complications in 64 (11.0%) versus 90 (12.3%; OR: 0.89; CI: 0.62 to 1.27; p = 0.52) of patients with continuation and with interruption of anticoagulation, respectively. Transfusion of packed red blood cells was less often required in patients with continuation of anticoagulation (80 [13.7%] vs. 130 [17.7%]; OR: 0.59; 95% CI: 0.42 to 0.81; p = 0.001). Kaplan-Meier estimates of survival at 12 months were 85.3% in patients with continuation of anticoagulation and 84.0% in patients with interruption of anticoagulation (hazard ratio: 0.90; 95% CI: 0.73 to 1.12; p = 0.36). CONCLUSIONS: Continuation of oral anticoagulation throughout TAVR did not increase bleeding or vascular complication rates. Moreover, packed red blood cell transfusions were less often required in patients with continuation of oral anticoagulation.

Repeat Transcatheter Aortic Valve Replacement for Transcatheter Prosthesis Dysfunction.

BACKGROUND: Transcatheter aortic valve replacement (TAVR) use is increasing in patients with longer life expectancy, yet robust data on the durability of transcatheter heart valves (THVs) are limited. Redo-TAVR may play a key strategy in treating patients in whom THVs fail. OBJECTIVES: The authors sought to examine outcomes following redo-TAVR. METHODS: The Redo-TAVR registry collected data on consecutive patients who underwent redo-TAVR at 37 centers. Patients were classified as probable TAVR failure or probable THV failure if they presented within or beyond 1 year of their index TAVR, respectively. RESULTS: Among 63,876 TAVR procedures, 212 consecutive redo-TAVR procedures were identified (0.33%): 74 within and 138 beyond 1 year of the initial procedure. For these 2 groups, TAVR-to-redo-TAVR time was 68 (38 to 154) days and 5 (3 to 6) years. The indication for redo-TAVR was THV stenosis in 12 (16.2%) and 51 (37.0%) (p = 0.002) and regurgitation or combined stenosis-regurgitation in 62 (83.8%) and 86 (62.3%) (p = 0.028), respectively. Device success using VARC-2 criteria was achieved in 180 patients (85.1%); most failures were attributable to high residual gradients (14.1%) or regurgitation (8.9%). At 30-day and 1-year follow-up, residual gradients were 12.6 ± 7.5 mm Hg and 12.9 ± 9.0 mm Hg; valve area 1.63 ± 0.61 cm2 and 1.51 ± 0.57 cm2; and regurgitation ≤mild in 91% and 91%, respectively. Peri-procedural complication rates were low (3 stroke [1.4%], 7 valve malposition [3.3%], 2 coronary obstruction [0.9%], 20 new permanent pacemaker [9.6%], no mortality), and symptomatic improvement was substantial. Survival at 30 days was 94.6% and 98.5% (p = 0.101) and 83.6% and 88.3% (p = 0.335) at 1 year for patients presenting with early and late valve dysfunction, respectively. CONCLUSIONS: Redo-TAVR is a relatively safe and effective option for selected patients with valve dysfunction after TAVR. These results are important for applicability of TAVR in patients with long life expectancy in whom THV durability may be a concern.

Treatment of failed aortic bioprostheses: An evaluation of conventional redo surgery and transfemoral transcatheter aortic valve-in-valve implantation.

BACKGROUND: The use of bioprostheses for surgical aortic valve replacement increased substantially within the last years. In case of prosthesis failure, re-SAVR is standard of care, whereas valve-in-valve deployment of a transfemoral transcatheter aortic valve prosthesis (VinV-TFAVI) has recently emerged as an alternative. We sought to evaluate early safety, clinical efficacy, and all-cause 1-year-mortality of VinV-TFAVI and redo surgery for failing aortic bioprostheses (re-SAVR). METHODS AND RESULTS: Patients receiving either VinV-TFAVI (n = 147) or re-SAVR (n = 111) for a degenerated aortic bioprosthesis between 01/2006 and 05/2017 were included in this analysis. All-cause 1-year mortality was the primary outcome measure. Early safety and clinical efficacy according to VARC-2 endpoint definitions were evaluated at 30 days. Baseline characteristics differed significantly between both groups including age, STS-PROM, and incidence of relevant comorbidities. Re-stenosis was the predominant mode of failure in 45.9% of re-SAVR and 63.1% of VinV-TFAVI patients. The rate of "early safety" endpoints was lower with VinV-TFAVI (17.7% vs. 64.9%, p < 0.01), the rate of "clinical efficacy" endpoints was lower, e.g. better with re-SAVR (53.1% vs. 32.4%, p < 0.01). All-cause 1-year-mortality (VinV-TFAVI 8.8% vs re-SAVR 9.9%, p = 0.84) was not different. Treatment strategy was not associated with 1-year-mortality in a Cox regression analysis. The incidence of prosthesis-patient-mismatch was higher in VinV-TFAVI compared to re-SAVR. CONCLUSION: VinV-TFAVI represents a viable alternative for treatment of degenerated aortic bioprostheses in patients at increased surgical risk. However, in patients at low risk for reoperation, a better clinical efficacy and acceptable safety may favour re-SAVR.

Outcome of patients with previous coronary artery bypass grafting and severe calcific aortic stenosis receiving transfemoral transcatheter aortic valve replacement.

OBJECTIVES: To evaluate the impact of previous coronary artery bypass grafting (CABG) on early safety at 30 days and 1-year mortality in patients receiving transcatheter aortic valve replacement (TAVR). BACKGROUND: The use of TAVR in patients with previous CABG suffering from severe aortic stenosis has increased in the last years. METHODS: Consecutive TAVR patients were stratified according to previous CABG versus no previous cardiac surgery (control). All-cause 1-year mortality and early safety at 30 days were evaluated. RESULTS: In the unmatched cohort and compared to control (n = 2,364), CABG (n = 260) were younger, more often male and suffered more often from comorbidities leading to an increased STS-score (p < .001). The rate of early safety events at 30 days was comparable between CABG and control (21.2% vs. 24.6%, p = .22) with a higher mortality in CABG (9.6% vs. 5.3%, p = .005). All-cause 1-year mortality was higher in CABG compared to controls (HR 1.51 [95%-CI 1.15-1.97], p = .003). Applying Cox regression analysis, both 30-day (HR 1.57 [95%-CI 0.97-2.53], p = .067) and all-cause 1-year mortality (HR 1.24 [95%-CI 0.91-1.70], p = .174) were not significantly different between groups. After propensity-score matching, the rate of early safety events at 30 days was lower in CABG compared to controls (21.6% vs. 31.7%, p = .02). Thirty-day (9.1% vs. 7.7%, p = .596) and all-cause 1-year mortality (24.0% vs. 23.1%, p = .520, HR 1.14 [95%-CI 0.77-1.69], p = .520) were not different between groups. CONCLUSION: In patients receiving TAVR, previous CABG was not associated with an increase in periprocedural complications and all-cause 1-year mortality when adjusted for other comorbidities.

Continued Versus Interrupted Oral Anticoagulation During Transfemoral Transcatheter Aortic Valve Implantation and Impact of Postoperative Anticoagulant Management on Outcome in Patients With Atrial Fibrillation.

The role of continued versus interrupted oral anticoagulation (OAC) in patients with atrial fibrillation (AF) who underwent transfemoral transcatheter aortic valve implantation (TF-TAVI) for severe aortic stenosis is uncertain. The aim of this retrospective investigation was to evaluate the impact (1) of continued versus interrupted OAC on early safety and (2) of postoperative anticoagulant management on the 1-year mortality in patients with AF who underwent TF-TAVI. Consecutive patients with AF and on OAC at admission (n = 598) were stratified according to interrupted (iVKA) versus continued vitamin K antagonist (cVKA) versus continued direct oral anticoagulants (DOAC) at the time of TF-TAVI. Valve Academic Research Consortium-2 early safety was the primary outcome measure. Patients with iVKA (n = 299), cVKA (n = 117), and DOAC (n = 182) had comparable baseline characteristics including age (p = 0.25), gender (p = 0.33), and STS-Score (p = 0.072). The proportion of patients having a CHA2DS2-VASc-Score ≥3 (p = 0.791) and HAS-BLED-Score ≥3 (p = 0.185) was not different between groups. The rate of early safety events (with lower values indicating superior safety) was lowest in DOAC (13.2%) and not increased in cVKA (19.7%) compared to iVKA (23.1%) (p = 0.029). Valve Academic Research Consortium-2 defined stroke (p = 0.527) and bleeding (p = 0.097) did not differ between groups. Renal failure occurred more often in iVKA compared to cVKA and DOAC (p = 0.02). All-cause 1-year mortality was 20.1% in iVKA, 13.7% in cVKA, and 8.8% in DOAC (p = 0.015). Multivariate analysis revealed DOAC to be associated with reduced all-cause 1-year mortality (HR 0.56 (95%-CI 0.32 to 0.99), p = 0.047) whereas cVKA was comparable to iVKA (HR 0.75 (95%-CI 0.43 to 1.31), p = 0.307). In conclusion, cVKA did not increase the rate for the composite end point of early safety at 30 days in this cohort of patients. Treatment with a DOAC was associated with a significantly reduced rate of early safety end points at 30 days and lower 1-year mortality.
