Abstract
Objective This study aimed to assess short-term outcomes of patients with failed aortic valve bioprosthesis undergoing valve-in-valve transcatheter aortic valve replacement (ViV-TAVR) or redo surgical aortic valve replacement (rSAVR). Methods Between 2009 and 2019, 90 patients who underwent ViV-TAVR (n = 73) or rSAVR (n = 17) due to failed aortic valve bioprosthesis fulfilled the inclusion criteria. Groups were compared regarding clinical end points, including in-hospital all-cause mortality. Patients with endocarditis and in a need of combined cardiac surgery were excluded from the study. Results ViV-TAVR patients were older (78.0 ± 7.4 vs. 62.1 ± 16.2 years, p = 0.012) and showed a higher prevalence of baseline comorbidities such as atrial fibrillation, diabetes mellitus, hyperlipidemia, and arterial hypertension. In-hospital all-cause mortality was higher for rSAVR than in the ViV-TAVR group (17.6 vs. 0%, p < 0.001), whereas intensive care unit stay was more often complicated by blood transfusions for rSAVR patients without differences in cerebrovascular events. The paravalvular leak was detected in 52.1% ViV-TAVR patients compared with 0% among rSAVR patients (p < 0.001). Conclusion ViV-TAVR can be a safe and feasible alternative treatment option in patients with degenerated aortic valve bioprosthesis. The choice of treatment should include the patient's individual characteristics considering ViV-TAVR as a standard of care.
