This study was performed to evaluate the late outcomes of Balloon Pulmonary Valvuloplasty (BPV) in children with residual infundibular stenosis."n"nMethods : Seventy-eight patients underwent BPV in Rajaee Heart Center in Tehran Iran, from 2008-2010. The patients were divided into two groups: with and without infundibular stenosis. The group with infundibular stenosis was subdivided into two groups: with and without propranolol administration. Gradient measurement follow-ups by Doppler echocardiography were done on the first day and 1, 3, 6 and 12 months afterwards."n"nResults: Thirty five (44.9%) patients were male and 43 (55.1%) were female. The mean age of participants was 4.29±3.5 years and the mean weight 16.18±8.8 kg 33 patients (43%) did not show residual infundibular stenosis but 45 (57%) did so in the evaluations. There were no significant differences between the two groups regarding age, weight, sex, kind of balloon valvuplasty, balloon to body surface area ratio and pulmonary regurgitation (PR). Propranolol was administered to 27 (60%) patients with residual stenosis for six months but 18 (40%) did not receive the medication. In both groups, the gradient significantly decreased immediately after BPV (P
