Transcatheter heart valve implantation generally requires both a ventricular guidewire and a temporary transvenous pacemaker (TVP). TVP insertion is not without risks, namely vascular injury, cardiac perforation and tamponade1. The modification of a ventricular guidewire to deliver unipolar pacing for transcatheter aortic valve implantation (TAVI) has ...
