عنوان انگلیسی An Interesting Anomalous Coronary Artery: Right Coronary Artery Arising from the mid Part of the Left Anterior Descending Artery
چکیده انگلیسی مقاله A 48-year-old woman was admitted to the emergency department with complaints of typical chest pain, cold sweat, and dyspnea of 24 hours’ duration. She had a history of hypertension, hyperlipidemia, and diabetes mellitus for many years. On admission, her electrocardiogram (ECG) revealed normal sinus rhythm and dynamic T inversion in the precordial leads. Her enzyme levels were normal. Transthoracic echocardiography showed a left ventricular ejection fraction of 60%, with mild mitral regurgitation. Because of ST depression during the peak exercise test, cardiac catheterization was suggested and then performed. Coronary angiography demonstrated normal left main coronary artery courses with normal dominant left circumflex artery and left anterior descending artery (LAD). An anomalous right coronary artery (RCA) was seen, with a nondominant separate branch arising from the mid part of the LAD. It then coursed anteriorly down on the right atrioventricular groove (Figure 1). Attempts for the cannulation of the RCA were unsuccessful. Aortic root angiography did not show the presence of an independent-origin RCA from the ascending aorta (Figure 2 and Figure 3). We selected medical management of X syndrome (microvascular disease) and followed up the patient because of the nondominancy of the RCA. There was no need for revascularization or surgery.  She was discharged in good condition.
