Giant coronary-to-bronchial arterial anastomosis complicated by myocardial infarction.
A patient with giant extracardiac coronary anastomosis connecting the proximal right coronary artery and the right bronchial artery of the right middle and lower lobes had an inferior myocardial infarction. The pulmonary arteries were hypoplastic and those of the right middle and lower lobes were completely occluded. Left pulmonary arteries were also diffusely hypoplastic. Furthermore, this patient with rare coronary-to-bronchial arterial anastomosis and pulmonary arterial occlusion suffered from inferior myocardial infarction in the distal area of the anastomosis. This appears to be the first case of myocardial infarction reported in this type of anomaly.
