Abstract
In recent years, TAVI using the cusp overlap projection, or cups-overlap technique (POC), has been postulated as a new alternative for the higher implantation of self-expanding bioprostheses.
The aim of this review is to describe the POC technique and to analyze the reported experience in comparison with the coplanar or standard technique.
TAVI procedures with self-expanding bioprostheses using the POC technique have been shown to be safe and have been associated with better commissural alignment and a higher prosthetic implantation depth, which leads to lower rates of conduction disorders and permanent pacemaker implantation. However, this technique has been associated with higher radiation doses during the procedure.
