Truncus Arteriosus

Abstract

We have encountered difficulty in recognizing and identifying clinically true truncus arteriosus with pulmonary arteries (type 1) because of its resemblance to correctable cardiac defects such as patent ductus arteriosus, aortic-pulmonic defect, and ventricular septal defect. In the present report we are presenting clinical information on 14 patients with this anomaly, both to supplement the scanty data available in the literature and to emphasize the need for correct diagnosis.
