Abstract:

Objective　To explore the incidence of anatomic variations of the coronary arteries in Chinese and sum up the experience of interventional therapy to the anomalous origin coronary artery with stenosis.　Methods　We reviewed 3015 patients undergone coronary angiography(CAG) in 2010，analyzed 42 anatomic variations of coronary artery, and summed up percutaneous coronary intervention(PCI) on 5 patients of anomalous origin coronary artery with stenosis.　Results　Among all patients undergone CAG, 42 cases had anatomic variation, with an incidence of 1.39%. Anomalous origin coronary artery appeared in 28 cases(0.93%), coronary pulmonary-artery fistula appeared in 8 cases(0.27%), the left ventricular fistula in 2 cases(0.07%), the right ventricular fistula in 2 cases(0.07%), the left atrium fistula in 1 case(0.03%), and the arteriovenous fistula in 1 case(0.03%). PCI was performed successfully in 4 cases, failed in 1 case, and no major complication happened.　Conclusions　PCI to the patients of anomalous origin coronary artery with stenosis is safe and feasible.
