Congenital peripheral pulmonary stenosis. Presentation of 16 cases and review of the literature

Abstract

Sixteen cases of peripheral pulmonary stenosis have been studied clinically and by cardiac catheterization. Diagnosis has been proved in all cases by manometric measurements and/or cineangiocardiography. All patients except two were below 2 years of age. Ten cases were of type I, i.e. the stenosis was localized to the pulmonary trunk or its main branches. Six patients were of type III, i.e. they had diffuse stenosis of the pulmonary arterial tree. The physical findings, which in many cases are typical and include the presence of a systolic murmur over both lung fields, should alert the physician to the diagnosis at the bedside. At cardiac catheterization the configuration of the pressure tracing in the main pulmonary artery is typical, showing an abrupt rise and fall of the systolic wave followed by a low situated dicrotic notch. There is no doubt that in the past many cases of peripheral pulmonary stenosis have been wrongly diagnosed as "essential pulmonary hypertension".
