Redo Robotic-Assisted Transcatheter Mitral Valve Replacement in a
Patient with Mitral Annular Calcification
Abstract
Mitral valve replacement in the setting of mitral annular calcification
(MAC) remains a surgical challenge fraught with several known
complications. We present an innovative and hybrid approach involving
robotic-assisted deployment of a SAPIEN S3 (Edwards Lifesciences,
Irvine, CA) in the mitral position of a patient with severe MAC in the
setting of previous sternotomy for aortic valve replacement. The robotic
platform allowed avoidance of redo sternotomy, paravalvular leaks
adjustment through excellent visualization from the right chest, and
better assessment of the risk of left ventricular outflow tract
obstruction. This report serves as an alternative technique for the
management of mitral valve surgery associated with MAC in the era of
transcatheter and minimally-invasive cardiac operations.
