Quadricuspid Neoaortic Valve in Truncus Arteriosus Type II

Stenotic semilunar valve in persistent truncus arteriosus.

The clinical, hemodynamic, and pathologic findings in two newborn infants with persistent truncus arteriosus and stenosis of the truncal valve are described. In one case the anatomic features of the basic condition were classic, with a dysplastic semilunar valve which was mainly stenotic and also incompetent, while in the other the truncus arteriosus arose exclusively from the right ventricle a...

Truncus Arteriosus

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 sc...

Echocardiography in truncus arteriosus. The value of pulmonic valve detection.

Nine patients with a clinical presentation suggestive of truncus arteriosus were examined by echocardiography. Subsequent intracardiac studies including cardiac catheterization and angiocardiography divided this group into five patients with truncus arteriosus and four patients with other congenital heart diseases. In all patients with proven truncus arteriosus, it was possible to identify only...

Persistent Truncus Arteriosus

PERSISTENT truncus arteriosus is one of the rarer congenital cardiac anomalies. Keith et al.1 cite the incidence to be less than 1 per cent of their congenital cardiac patients Abbott2 found 21 in her autopsy series of 1,000 cases and Wood3 had one in his clinical series of 900. Collett and Edwards4 reviewed, in an excellent study of 80 autopsied cases, the pathology of truncus arteriosus. The ...
