New Pulmonary Valvuloplasty Technique by Use of an Hourglass-Shaped Balloon in 3 Adults with Severe Pulmonary Valve Stenosis.

Abstract

Percutaneous balloon pulmonary valvuloplasty is the preferred therapy for pulmonary valve stenosis. However, the designs of the cylindrical balloons historically used for valvuloplasty have limitations, especially in patients who have large pulmonary annular diameters. The hourglass-shaped V8 Aortic Valvuloplasty Balloon may prove to be an effective alternative. The balloon has 2 large bulbous segments that are separated by a narrowed waist. The geometric shape is maintained throughout inflation, improving fixation and enabling broader leaflet opening. We present our first experience with the V8 balloon in 3 adults who had severe, symptomatic pulmonary valve stenosis. In addition to describing their cases, we detail our sizing technique for pulmonary valvuloplasty with the V8 balloon. Our successful results suggest that the V8 balloon is efficient and safe for balloon pulmonary valvuloplasty in adults with severe pulmonary valve stenosis.
