Importance of the left ventricular outflow tract in the need for pacemaker implantation after transcatheter aortic valve replacement

The interaction of left ventricular outflow tract (LVOT) and transcatheter heart valve (THV) is complex and may be device design specific. We sought to study LVOT characteristics and its relation with permanent pacemaker implantation (PPI) after transcatheter aortic valve replacement (TAVR).
