Valvar stenosis in truncus arteriosus.

Valvar stenosis in truncus arteriosus.

Twenty three morphological specimens of truncus arteriosus were examined for evidence of stenosis of the semilunar valve. One third showed good evidence of stenosis as judged by careful measurement of the valve orifice, the valve ring, and the maximum diameter of the truncus. Correlation with measured pressure gradients was poor, but angiography and cross sectional echocardiography were better ...

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...

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 ...
