Novel Techniques to Crossing a Severely Stenotic Aortic Valve

Ibrahim Yearoo et al. JACC Case Rep. .

Abstract

This report presents 2 cases with the use of different techniques to facilitate aortic valve crossing during transcatheter aortic valve replacement with a balloon-expandable system. Case 1 involves a balloon cushion technique with an Edwards Sapien 3 valve (Edwards Lifesciences), and case 2 describes successful crossing and implantation using a buddy balloon technique with an Edwards Sapien Ultra valve. (Level of Difficulty: Advanced.).

Keywords: AV, aortic valve; LV, left ventricular; TAVR, transcatheter aortic valve replacement; aortic valve; imaging; valve replacement.

(B) Mean annular measurement (25 mm). (C) The sinus of Valsalva measurements (biplane 33× 32.8 mm). (D) Failure to cross the aortic valve despite considerable push and manipulation. (E) Inflation of 1 to 2 cm3 of the distal part of the balloon (blue arrow highlighting the outline of contrast). (F) Successful crossing of the aortic valve following the balloon cushion technique. L = left; MSCT = multislice computed tomography; N = node; R = right.

Angiographic Views Demonstrating Difficulty in Crossing the Aortic Valve and Rescue Maneuvers With the Buddy Balloon Technique (A) Sapien Ultra valve (Edwards Lifesciences) and delivery system were unable to cross the aortic valve. (B) Sapien Ultra valve on the outer curve bias despite delivery system and wire coaxial maneuvers. (C) Failure to cross despite use of a Cristal balloon (Balt extrusion; 20- × 45-mm) for valvuloplasty. (D) Deflating and withdrawing the buddy balloon across the aortic valve (blue arrow) while advancing the Sapien Ultra valve (red arrow) to facilitate successful crossing. (E) Successful crossing and implantation of the Sapien Ultra valve.
