Iranian Heart Association Iranian Heart Journal 9 1 2008 03 01 Congenital Coronary Artery Fistulas: Report of Three Rare Cases 64 68 182396 EN Journal Article 2007 07 22 Coronary artery fistula is a rare congenital anomaly with an incidence of about 0.2 - 0.6% in<br />different reports. It is defined as a direct communication between the coronary artery and any<br />surrounding cardiac chamber or vascular structure which bypasses the myocardial capillary bed.<br />Three interesting cases of coronary artery fistula are reported. Two of the patients were<br />symptomatic. In one case, all coronary arteries (in addition to duplicated LAD) were fistulized into<br />the right ventricle. Diagnosis was made by echocardiographic study and coronary angiography.<br />Surgical correction is discussed. In one case, angiography six months later showed no fistula. Serial<br />echocardiography during follow-up was unremarkable (Iranian Heart Journal 2008; 9 (1):64 -68). https://journal.iha.org.ir/article_182396_10dae2db89bc660a12ae0a03ec03a28d.pdf
