Abstract

Objective: Immediate, short and midterm outcome of balloon pulmonary valvuloplasty are well known, but there is limited information on long term results. We report long term results of 2-13. 5 years follow up of balloon pulmonary valvuloplasty in children. Methods: From June 1998 to January 2012 sixty consecutive patients (33 females, 27 males) with moderate to severe valvar pulmonary stenosis (right ventricular to pulmonary artery pressure gradient greater than 50 mmHg) were considered for balloon valvuloplasty. The gradient was measured pre and immediately post- valvuloplasty at catheterization, and then by echocardiography at follow up. Follow up studies were performed 2-13.5 years (mean&
