Radiologic diagnosis of different types of pulmonary stenoses.

Abstract

Right ventricular outflow obstructive lesions are among the most prevalent congenital cardiac anomalies with a frequency ranging from 6--10% when considered as isolated anomalies. As part of a more complicated developmental complex, their frequency is undoubtedly higher. The diagnosis can be suspected by the traditional clinical and hemodynamic findings, but a firm diagnosis can only be made by angiography. An exact diagnosis is most important since most of these lesions can be surgically corrected.
