Cusp Overlap Technique: Should It Become the Standard Implantation Technique for Self-expanding Valves?

ABSTRACT:

Purpose of review

Accurate imaging of the aortic root during valve implantation is crucial for proper prosthesis positioning during TAVR. The purpose of this review was to determine if routine use of the cusp-overlap view should be adopted for self-expanding valves.

Recent findings

The use of the cusp-overlap view with the Evolut, Portico, ACURATE neo/neo2, and JenaValve systems is associated with lower post-procedural new permanent pacemaker implantation rates when compared with the standard 3-cusp view, presumably due to more precise valve implantation relative to the conduction system by the non-coronary cusp. By elongating the left ventricular outflow tract and accentuating the right-non commissure in the center of the fluoroscopic view, the cusp-overlap technique allows
