Brief summary

The purpose of this study is to generate clinical evidence on valve safety and performance in subjects treated by redo Transcatheter Aortic Valve Replacement (TAVR).

Detailed description

Interventions

DEVICEMedtronic TAV

Medtronic TAV where commercially available

DEVICEEdwards TAV

Inclusion criteria

* BVF of a TAV (either Medtronic or Edwards) requiring redo TAVR

Exclusion criteria

* BVF due solely to paravalvular regurgitation * Active endocarditis * Untreated acute valve thrombosis * Life-expectancy less than 1-year * Subject is less than legal age of consent, legally incompetent, or otherwise vulnerable * Participating in another study that may influence the outcome of this study

Design outcomes

Primary

MeasureTime frameDescription
Primary Outcome MeasureEarly (30-days)30-day redo TAVR success defined as correct positioning of a single redo prosthetic heart valve into the proper anatomic location, intended performance of the valve (mean gradient \<20mmHg, peak velocity \<3 m/s, Doppler velocity index (DVI) ≥0.25, aortic regurgitation (AR) \< moderate), and freedom from all-cause mortality, coronary obstruction, unplanned coronary revascularization, and surgery or intervention related to the device
