Outcomes of Balloon Pulmonary Valvuloplasty at Maharat Nakhon Ratchasima Hospital during July 2001- January 2005

Abstract

Background: Balloon pulmonary valvuloplasty has been accepted as standard treatment of congenital pulmonary valvular stenosis with excellent results. Aim: To study the outcomes of Balloon pulmonary valvuloplasty at Maharat Nakhon Ratchasima Hospital during July 2001 – January 2005. Patient & Methods: Prospective study was performed. The patients were classified to moderate or severe degree of pulmonary stenosis. Results: Thirty- six cases of pulmonary valvular stenosis were treated. The patients comprised 15 males (41.6%) and 21 females (58.4%), whose mean age was 16.1 ± 12.8 years. Twelve cases (33.3%) had moderate degree of stenosis while 24 cases (66.7%) had severe degree of stenosis. Thirty-four of 36 cases had isolated pulmonary valvular stenosis. Only2 cases had pulmonary stenosis as a part of Tetralogy of Fallot. The successful rate was 88.9% (32 cases). Only 2 cases (5.5%) had complications during procedure, one developed transient supraventricular tachycardia with spontancous sinus conversion after balloon off and the other had bleeding at puncture site (femoral vein) after withdrawal of the femoral sheath which was stopped after an hour compression. There was no serious complications or death in this study. Increase of pulmonary vasculature was significantly detected by chest X-ray after 6-12 months. There was no restenosis within 1 year ballooning. Conclusion: Balloon pulmonary valvuloplasty for pulmonary value stenosis at Maharat Nakhon Ratchasima Hospital was successfully performed with excellent outcomes.
