Prosthetic valve endocarditis after transcatheter aortic valve implantation
Circulation. Cardiovascular interventions, 2015
Transcatheter aortic valve implantation (TAVI) is an advancing mode of treatment for inoperable or high-risk patients with aortic stenosis. Prosthetic valve endocarditis (PVE) after TAVI is a serious complication, but only limited data exist on its incidence, outcome, and procedural risk factors. Observational single-center study of 509 consecutive patients treated with a transcatheter implanted self-expandable aortic valve prosthesis (Medtronic CoreValve). We identified 18 patients diagnosed with TAVI-PVE during a median follow-up period of 1.4 years (interquartile range, 0.5-2.5 years; longest follow-up was 6.3 years). TAVI-PVE was most frequent in the first year after implantation (first-year incidence, 3.1% [confidence interval, 1.4%-4.8%]); the overall annualized rate was 2.1% per patient-year (confidence interval, 1.2%-3.3%). Seventeen patients (94%) were treated conservatively and 1 with surgery. Four patients (22%) died from endocarditis or complications to treatment, 2 of t...

Objectives: The number of transcatheter aortic valve implantations (TAVI) has increased enormously in recent decades. Transcatheter valve prosthesis failure and the requirement of conventional surgical replacement are expected to attract more focus in the near future. Indeed, given the scarcity of research in this field, the next decade will likely represent the beginning of a period of meaningful exploration of the degenerative changes that occur with transcatheter valves. The current study represents—through a series of consecutive cases—one of the first analyses of the underlying causes of TAVI failure, i.e., degenerative, functional and infective, followed by surgical aortic valve replacement (SAVR) and postoperative outcome. Methods: Between October 2008 and March 2021, 2098 TAVI procedures, including 1423 with transfemoral, 309 with transapical, and 366 with transaortic access, were performed in our institution. Among these, 0.5% (number(n) = 11) required acute SAVR (n = 6) wi...

Valve-in-valve (ViV) transcatheter aortic valve replacement (TAVR) has been shown to be feasible, yet the safety and efficacy in relation to native valve (NV) TAVR are not known. This study sought to evaluate the safety and effectiveness of ViV TAVR for failed surgical aortic valve replacement (SAVR) by comparing it with the benchmark of NV TAVR. Patients who underwent ViV-TAVR (n = 1,150) were matched 1:2 (on sex, high or extreme risk, hostile chest or porcelain aorta, 5-m-walk time, and Society of Thoracic Surgeons Predicted Risk of Mortality for reoperation) to patients undergoing NV-TAVR (n = 2,259). Baseline characteristics, procedural data, and in-hospital outcomes were obtained from the Transcatheter Valve Therapy Registry. The 30-day and 1-year outcomes were obtained from linked Medicare administrative claims data. Unadjusted analysis revealed lower 30-day mortality (2.9% vs. 4.8%; p < 0.001), stroke (1.7% vs. 3.0%; p = 0.003), and heart failure hospitalizations (2.4% vs....

OBJECTIVES Vascular complications (VC) are the most frequent drawback of transcatheter aortic valve implantation (TAVI), affecting up to 20% of overall procedures. Data on the treatment and their long-term impact are scarce. The goal of this study was to report on the incidence, management and impact on the long-term outcomes of VC following TAVI. METHODS This was a multicentric retrospective analysis of consecutive patients undergoing TAVI. The primary endpoint was freedom from major adverse cardiac and cerebrovascular events at long-term follow-up. Adverse events were evaluated according to Valve Academic Research Consortium-2 criteria. RESULTS A total of 2145 patients were included: VC occurred in 188 (8.8%); of which 180 were limited to the access site. Two-thirds of the VC were minor; 8% required surgical treatment; the remaining were repaired percutaneously. The major adverse cardiac and cerebrovascular events-free survival at 2 years was 83.0% for patients with VC and 86.7% f...
