BACKGROUND Severe pure aortic regurgitation (AR) carries a high mortality and morbidity risk, and it is often undertreated because of the inherent surgical risk.

RESULTS Overall, 256 patients were enrolled. THVs used off-label were used in 168 cases (66%), whereas JVT was used in 88 (34%). JVT had higher technical (81% vs 98%; P < 0.001) and device success rates (73% vs 95%; P < 0.001), primarily driven by signi ficantly lower incidences of THV embolization (15% vs 1.1%; P < 0.001), the need for a second valve (11% vs 1.1%; P = 0.004), and moderate residual AR (10% vs 1.1%; P = 0.007).

Abstract

BACKGROUND Severe pure aortic regurgitation (AR) carries a high mortality and morbidity risk, and it is often undertreated because of the inherent surgical risk. Transcatheter heart valves (THVs) have been used off-label in this setting with overall suboptimal results. The dedicated "purpose-built " Jena Valve Trilogy (JVT, JenaValve Technology) showed an encouraging performance, although it has never been compared to other THVs. OBJECTIVES The aim of our study was to assess the performance of the latest iteration of THVs used off-label in comparison to the purpose-built JVT in inoperable patients with severe AR. METHODS We performed a multicenter, retrospective registry with 18 participating centers worldwide collecting data on inoperable patients with severe AR of the native valve. A bicuspid aortic valve was the main exclusion criterion. The primary endpoints were technical and device success, 1-year all-cause mortality, and the composite of 1-year mortality and the heart failure rehospitalization rate. RESULTS Overall, 256 patients were enrolled. THVs used off-label were used in 168 cases (66%), whereas JVT was used in 88 (34%). JVT had higher technical (81% vs 98%; P < 0.001) and device success rates (73% vs 95%; P < 0.001), primarily driven by signi ficantly lower incidences of THV embolization (15% vs 1.1%; P < 0.001), the need for a second valve (11% vs 1.1%; P = 0.004), and moderate residual AR (10% vs 1.1%; P = 0.007).
