Pulmonary valve stenosis

Abstract

Valvular pulmonary stenosis (PS) frequently presents with an asymptomatic systolic murmur but seldom with exercise intolerance. Mild PS is rarely progressive; however, moderate PS can progress to significant stenosis and secondary hypertrophy in the infundibulum; of course, this lesion exists as a continuum, ranging from isolated mild valvular PS to complete atresia of the pulmonary outflow tract [1, 2].
