title: Two-dimensional echocardiographic evaluation of persistent truncus arteriosus.
abstract: Using a phased-array, wide angle sector-scanner, 2-dimensional echocardiograms were obtained in 3 patients with persistent truncus arteriosus. Type I was found in 2 patients and type II in 1 patient. In the patient with type II truncal valve stenosis was also present. Using a combination of short-axis views at the cardiac base, within 30 degrees superior transducer angulation and parasternal long-axis views, the truncus arteriosus and the pattern of pulmonary arteries were demonstrated in each case.
