BICORN (Bilateral Iatrogenic Coronary Obstruction Risk Nullification) Procedure for Transcatheter Aortic Valve-in-Valve Replacement.

ABSTRACT:

Objectives

We describe a bilateral coronary leaflet modification technique that involves translocation of degenerated transcatheter valve leaflets before placement of valve-in-valve, named Bilateral Iatrogenic Coronary Obstruction Risk Nullification (BICORN).

Key steps

Key steps include the following: 1) Electrified 0.014-in ASTATO wires were traversed through the base of the right and left coronary leaflets of preexisting CoreValve, which were then swapped with 0.035-in wires; 2) Using peripheral balloons, leaflet traversal points were appropriately dilated; 3) A 26-mm Sapien valve was then advanced over the wire through the left coronary leaflet to the ascending aorta in a deployment-ready state; and 4) Right coronary leaflet was then translocated with 18-mm True balloon f
