Popis: Coronary artery anomalies are rare, with their incidence varying from 1 to 5%. Angiography is a commonly used modality for the assessment of coronary artery anomalies. Based on previous reports, a majority of coronary artery anomalies are of origin or distribution, with separate ostia of the left anterior descending artery and left circumflex artery. Coronary artery anomalies may cause myocardial ischemia secondary to atherosclerosis in the same artery. We present a rare case of duplicated right coronary artery with a separate ostium, which caused myocardial ischemia. Our patient was a 51-year-old diabetic woman with typical chest pain and dyspnea on exertion. Electrocardiography showed left axis deviation, poor R progression, and biphasic T wave in the precordial leads. Echocardiography revealed left ventricular ejection fraction of 30–35% and global hypokinesia. Coronary angiography demonstrated three-vessel disease and a double ostial right coronary artery. We recommended coronary artery bypass graft surgery, but the patient refused it and we continued her treatment with anti-ischemic drugs.
