简要总结
The primary objective of the INSPIRIS RESILIA Aortic Valve-in-valve (ViV) Surveillance Study ("the Study") is to capture Adverse Event information and valve measurement data from dysfunctional INSPIRIS RESILIA aortic valves before and after Valve-in-valve (ViV) treatment.
详细描述
This is a single-arm observational study which includes both prospective and retrospective data.
At least fifty (50) Subjects enrolled prospectively prior to the ViV procedure, or retrospectively after the ViV procedure (within 37 days post-ViV procedure) with dysfunctional 19mm-25mm INSPIRIS aortic valves, will participate in this study.
All subjects will be followed for up to 1 month after the TAVR ViV procedure.

结局指标
主要结局
Subject's Occurrence Rate of the Composite Safety Endpoint
时间窗: Events occurring within 30 days of valve-in-valve procedure
The primary safety endpoint is a composite endpoint defined as all-cause mortality, all stroke (disabling and non-disabling), life-threatening bleeding, new requirement for dialysis, coronary artery compression or obstruction, major vascular complication, and valve-related dysfunction requiring reintervention. Data will be reported as the number (and percent) of subjects who experience an event divided by the number of enrolled subjects times 100.
Subject's Occurrence Rate of Valve Malpositioning
时间窗: Events occurring within 30 days of valve-in-valve procedure
Valve malpositioning includes all instances of ViV-TAVR migration, embolization, and valve recapture or retrieval. Data will be reported as the number (and percent) of subjects who experience an event divided by the number of enrolled subjects times 100.
Subject's INSPIRIS RESILIA Valve Expansion Post Valve in Valve Procedure Compared to Baseline
时间窗: Day 30, compared to baseline
A primary effectiveness endpoint is the expansion, measured in mm\^2, of INSPIRIS valve for sizes 19mm-25mm, following the Edwards transcatheter aortic valve implantation.
次要结局
