Description
Front view shows a dilated right ventricle (R) and a pulmonary artery (P) that is about four times the size of the aorta (A). A small patent ductus arteriosus (short arrow) connects the two.
Comment
Aortic valvular atresia is part of a spectrum of obstructing malformations of the left ventricular outflow tract, which can occur in sub-valvular, valvular, or supra-valvular regions. When the valve is the site, it can be monocuspid, bicuspid, tricuspid (often dome shaped) or quadricuspid. It can be an isolated anomaly or associated with a hypoplastic left ventricle.
