    AbstractA little is known about long-term hemodynamic performance of the transcatheter heart valves (THVs). The aim of the present study was to assess hemodynamic outcome, structural valve deterioration (SVD) and bioprosthetic valve failure (BVF) in patients treated with transcatheter aortic valve replacement (TAVR) five or more years ago. All consecutive patients treated at Bologna and Florence University Hospitals with TAVR between January 2008 and December 2013 were analyzed in a retrospective registry with regards to demographic, procedural and outcome data as well as follow-up data on mortality and echocardiographic characteristics. Standardized definitions were used to define outcomes and durability of the THVs. 400 patients were included in the study, mostly treated with transfemoral TAVR (71.8%), using first generation balloon-expandable (37%) or self-expanding (63%) devices. The 1-year mortality was 21.8% (87 patients) and 5-year mortality was 53.8% (215 patients). Median follow-up was 45.5 months (14.0-68.9) totaling 1516.7 patient/years, with the longest follow-up being 10.25 years. At least one follow-up echocardiogram was available for 320 patients (80%), SVD occurred in 19 of these patients (5.94%): moderate in 17 patients (5.31%) and severe in two patients (0.63%). The hemodynamic presentation was stenosis in most of the cases (12 patients). Late BVF was registered in 10 patients (3.13%) and this was mainly driven by transcatheter paravalvular leak closure (six patients) with subsequent good long-term outcome. Our results confirm that TAVR appears to be a long-lasting treatment strategy with low rates of structural valve degeneration and valve failure.© 2021. Società Italiana di Medicina Interna (SIMI).
