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...

INTRODUCTION Truncus arteriosus with intact ventricular septum is a rare and unique variant of persistent truncus arteriosus (PTA) which usually presents with central cyanosis and congestive heart failure in neonate and early infancy. Associated cardiac and non-cardiac anomalies may affect morbidity and mortality of these patients. CASE PRESENTATION We describe clinical presentation, echocard...

Persistent truncus arteriosus is characterized by a single arterial trunk arising from the heart and supplying the systemic, pulmonary, and coronary circulations. There are remnants neither of an atretic pulmonary artery nor aorta (Lev and Saphir, 1942; Collett and Edwards, 1949). Despite excellent clinical reviews (Anderson, Obata, and Lillehei, 1957; Tandon, Hauck, and Nadas, 1963; McCue et a...

The value of two dimensional echocardiography in identifying communications between the-ascending aorta and pulmonary trunk or individual pulmonary arteries was assessed in 24 children, all ofwhom had either angiocardiographic and surgical or angiocardiographic confirmation alone. Fourteen cases had truncus arteriosus, four aortopulmonary window, four anomalous origin of the left pulmonary arte...

Truncus arteriosus (TA) is defined as a congenital cardiovascular malformation in which one great artery arises from the base of heart and gives origin to pulmonary systemic arteries. TA patients who become pregnant have high morbidity mortality rates because physiologic changes during pregnancy can worsen cardiopulmonary balance causing decompensation. In this case report we successful general...

Two-dimensional echocardiography of a patient revealed overriding of the large aortic trunk which bifurcated above the semilunar valve, suggesting persistent truncus arterious. This diagnosis was confirmed by cardiac catheterization and angiocardiography. Surgery and autopsy also confirmed the accuracy of the two dimensional echocardiographic findings. Two-dimensional echocardiography is thus v...

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 ...

Successful correction of a type 2 truncus arteriosus in an African boy of 10 years is reported. The surgical technique employed is described and preoperative and late postoperative haemo-dynamic data are documented. Failure of the primitive truncus arteriosus to partition results in one of a group of congenital cardiac anomalies called persistent truncus arteriosus. A single vessel, guarded by ...
