This article is from Iranian Journal of Pediatrics, volume 23.AbstractObjective: 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±SD; 7.1±2.5 years, median: 5.5 years after procedure, by Doppler echocardiography in all patients and catheterization and angiography in two patients. Findings: Balloon pulmonary valvuloplasty BPV was successful in 53 of 60 88.3% patients whereas surgical valvotomy was necessary in 6 to 60 10%. There was one immediate death due to perforation of the right ventricular outflow tract. Pulmonary valve systolic pressure gradient decreased from 83.3±32.1 to 19.3±14.2 mmHg immediately after BPV and to 12.3±6.6 mmHg at late follow up P
