Pulmonary stenosis

Abstract

Pulmonary stenosis is an obstruction between the right ventricle and the pulmonary arteries. It has three different types: valvular, subvalvular and supravalvular or peripheric. It may be mild, moderate or severe according to the obstruction. Right ventricular hyperthrophy is essential and most prominent sign on oscultation is murmur and ejection click. Prognosis is generally good and most of the patients do not need any treatment or were treated by baloon valvuloplasty without surgery.
