title: [Central and peripheral coronary-pulmonary fistulae. Apropos of 4 case reports].
abstract: The authors report four cases of fistulae between coronary arteries and the main pulmonary artery or its branches. Proximal fistulae, often considered with coronary-cardiac fistulae (between coronary arteries and cardiac cavities, usually in the right heart) probably result from accessory coronary buds originating in the truncus arteriosus, on its pulmonary part, as in anomalous coronary arteries stemming from the pulmonary trunk. Two such cases are reported, including one in a girl with severe congenital mitral insufficiency. Peripheral fistulae probably do not result from a single mechanism, and their congenital or acquired origin is often difficult to determine, especially in adults. Nevertheless, in a 54-year-old female with angina by coronary steal, without any associated pulmonary disease, the fistula is probably congenital. On the other hand, in a boy who had a Blalock operation for Tetralogy of Fallot, the fistula is probably acquired, as part of the collateral circulation which developed after pleuro-pericardial symphysis. Such fistulae usually do not require surgery except in cases of coronary artery steal, which are exceptional in children but not infrequent in adults.
