A co-operative retrospective study of I7 patients with congenital coronary artery fistula was undertaken.The right coronary artery was the most common vessel involved and the right ventricle was the site of drainage in the majority of the patients. Three methods of drainage of the fistula into the chamber are described. The majority of the patients were under 20 years of age and were asymptomatic. All the patients above the age of 35 were symptomatic. The symptoms and the cardiomegaly on the chest x-ray were well correlated with the size and duration of the shunt.The physical signs, electrocardiograms, chest x-rays, cardiac catheterization data, and angiocardiographic features are described.

A case is presented of a male infant aged 8 weeks at the time of his death with pulmonary veno-occlusive disease. Almost all pulmonary veins and venules were narrowed or obstructed by intimal fibrosis with such a pronounced deposition of collagen and elastic tissue that an intrauterine origin of these lesions appeared likely. Bronchial veins and anastomoses between pulmonary and bronchial veins were also affected.The vascular changes were of a thrombotic nature.

Three cases of partial anomalous pulmonary venous return, in one case combined with coarctation of the aorta and in another with discrete subaortic stenosis, are described in patients with Turner syndrome. In two of them the right and left superior pulmonary veins drained into the right superior vena cava and left innominate vein respectively. Remarkably, in all three cases the atrial septum was intact. We feel that this unique combination probably is not purely coincidental, but might rather be specific for Turner syndrome.
