Pulmonary valve morphology after balloon dilatation of pulmonary valve stenosis.
Percutaneous balloon valvuloplasty (BV) for pulmonic valve stenosis (PS) is increasingly becoming a nonsurgical alternative in patient management. However, the mechanism by which BV dilates the obstructive lesion has not been firmly established. We have had the opportunity to examine the effects of BV in the setting of PS and present two illustrative cases documenting the morphology after BV of the stenotic bicuspid and tricuspid pulmonary valve.
