THE GENESIS OF COMMUNICATIONS between the right ventricle and coronary arteries commonly associated with pulmonary atresia remains uncertain. Edwards' attributed the persistence of these communicating sinusoids to increased right ventricular pressure and emphasized the importance of right ventricular outflow obstruction, intact ventricular septum, and competence of the tricuspid valve. Other au...

Microanigiographlic examinatioin of the pulmoniary arterial svstem in 12 n1ewborn in1fants with conicomitanit steniosis or atresia of the aortic anid mitral orifices showed that the intrapulmonary arterial pattern is inifluenced by the state of the forameni ovale. In inifanlts with aortic atresia with a prematuirely closed foramein ovale, that is cases in which the left side of the heart is a c...

BACKGROUND Patients with tetralogy of Fallot, pulmonary atresia, and diminutive pulmonary arteries are a high-risk group for whom there is no consensus on the correct approach to medical management. The purpose of this report is to review a 14-year experience in the treatment of these patients comparing management schemes. METHODS AND RESULTS Between January 1978 and August 1988, 91 patients ...

OBJECTIVE To assess the possibility of maintaining ductal patency in neonates with complex pulmonary atresia by percutaneous implantation of balloon expandable stents. PATIENTS Two duct-dependent neonates with long segment pulmonary atresia, right sided aortic arch, and left sided arterial duct. RESULTS Stents with final diameter of 3.5 or 4 mm and initial length of 7 or 15 mm were successf...

Fibromuscular dysplasia is a nonatherosclerotic and non-inflammatory vascular disease with primary lesion of renal and internal carotid arteries. We present a neonatal case of fibromuscular dysplasia who died on the second day of life. The newborn suffered from fibromuscular dysplasia of the coronary arteries and a congenital heart defect. The interesting feature of this case was the formation ...

A newborn with an unusual form of truncus arteriosus is described, whose clinical presentation and certain features of her anatomy were more typical of pulmonary atresia with a ventricular septal defect. The morphological differentiation of certain types of truncus arteriosus and pulmonary atresia with ventricular septal defect remains an area of speculation among cardiac pathologists, and rese...
