FIGURE 1. Baseline CT and Key Procedure Steps to Set Up CATHEDRAL.

FIGURE 1

(A and B) Prolapsing left leaflet and coronary obstruction risk by long leaflet. (C) Aortography, severe AR. (D) Prolapsing leaflet (asterisk) traversed with AstatoXS20 wire. (E) Flying V across leaflet. (F) 12-F sheath and guider with snare lasso advanced over Flying V and energized. (F) Inset: The snare is advanced over the “corner” of the leaflet torn from the commissure. With traction and rotation of the Flying V (red lines), the remaining part of the leaflet can be pulled into the snare. Dashed blue lines indicate the leaflet.

AR = aortic regurgitation; CT = computed tomography; CATHEDRAL = Catheter electrosurgical debulking and removal.
