Background: Sporadic cases of coronary artery fistula were reported in clinical journals. But until now, there are rare case reports of right coronary artery(RCA) to left ventricular(LV) fistula, that were mainly managed by surgical operation. In recent years, there have been an increasing number of reports concerned with percutaneous coil embolization for treatment of coronary artery fistula. We experienced a case of RCA to LV fistula treated with percutaneous coil embolization. Case: A 61-year-old man was admitted with a prolonged episode of typical anterior chest pain,aggravated by exercise. During TMT, chest pain developed at stage III with horizontal ST depression(>2mm) on II, III, aVF, V5, and V6 lead. Echocardiography revealed good global LV systolic function(LVEF 66%) without regional wall motion abnormality and chamber enlargement. But with color Doppler imaging, turbulent color flow was detected on inferior portion of LV cavity. Coronary angiography(CAG) and multidetector CT angiography revealed a tortuous and dilated RCA to LV fistula connection, associated with LV aneurysm at entry of the fistula. Successfully, we treated it with coronary artery coiling intervention without complication. Follow-up CAG showed no abnormal RCA to LV connections. Thereafter, he discharged from the hospital without any symptoms.
