Transcatheter mitral valve replacement in a complex mitral annular calcification anatomy.

ABSTRACT:

Background

Transcatheter mitral valve replacement (TMVR) is emerging as a feasible alternative to conventional surgical intervention in patients at high surgical risk, also those with severe mitral annular calcification (MAC). However, the presence of a previously implanted self-expanding transcatheter aortic valve prosthesis introduces considerable technical difficulties, especially due to the risk of left ventricular outflow tract obstruction.

Case summary

To our knowledge, it is among the very few reported cases of combined percutaneous interventions with a self-expanding valve in the aortic position and a balloon-expandable valve in the mitral position. During the procedure, circulatory arrest occurred, followed by the development of cardiac tamponade; both complications
