Abstract

Coronary artery fistulae are rare anomalous connections arising from the coronary circulation. We report a case of anterior wall myocardial ischemia caused by the combination of sequential coronary-to-pulmonary artery fistula and moderate (50-60%) stenosis of the left anterior descending coronary artery. Ischemia was demonstrated by myocardial stress perfusion imaging as well as fractional flow reserve. Percutaneous coronary intervention of the lesion resulted in resolution of ischemia.

摘要

冠状动脉瘘是一种罕见的冠状动脉循环异常连接。我们报告了一例前壁心肌缺血病例，其病因是序贯性冠状动脉-肺动脉瘘和左前降支冠状动脉中度狭窄（50-60%）共同作用所致。心肌应激灌注成像和血流储备分数证实存在缺血。病变的经皮冠状动脉介入治疗导致缺血缓解。
