Failure after mitral annuloplasty or replacement is one of the long-term complications after mitral surgery. Reoperation in this frail population is associated with high postoperative mortality and morbidity1. Transcatheter mitral valve replacement (TMVR) procedures, including mitral valve-in-valve (ViV), valve-in-ring (ViR) and valve-in-mitral annular calcification (ViMAC), have recently emerged as off-label alternative therapies for prosthesis dysfunction and severe mitral calcification2. Even though TMVR without rapid pacing has been successfully performed, it can improve valve stability and so optimises deployment and valve positioning. Temporary right ventricle pacing (RVP) is potentially associated with vascular and ventricular complications such as perforations and tamponades. Transcatheter ...
