Transcatheter aortic valve replacement in patients with a pre-existing prosthetic mitral valve: a single center experience with two cases.

ABSTRACT:

Background

The performance of transcatheter aortic valve replacement (TAVR) in patients with pre-existing prosthetic mitral valves is technically challenging due to the potential interference between both prosthetic devices. At present, there are no clear recommendations for this patient subset due to their exclusion from clinical trials. We report our experience of two cases with pre-existing prosthetic mechanical mitral valves who underwent TAVR.

Case presentation

The first case was a 57 year old man with severe aortic stenosis and type 2 diabetes mellitus who had a mitral valve replacement 32 years ago. Operative mortality risk assessed by the Society for Thoracic Surgery (STS) Score was 1.7%, but he was considered high risk in view of previous cardiac surgery. Pre-proced
