Project description:Anomalous aortic origin of a coronary artery (AAOCA) is a rare pathology that may cause episodic ischemia owing to possible vessel compression during systolic expansion of the aortic root. This anomaly can lead to myocardial infarction, malignant arrhythmias and sudden cardiac death (SCD). Several surgical techniques have been described; however, there are no defined guidelines regarding the treatment of AAOCA. We report the case of a 47-year-old woman with ectopic origin of the right coronary artery (RCA) from the left sinus of Valsalva, with an interarterial course of the proximal segment of the artery, running between the aorta and the pulmonary trunk. Revascularization was accomplished by harvesting the right internal mammary artery (RIMA) and anastomosing it to the anomalous RCA, given the small portion of the RCA following an intramural course and our familiarity with the procedure. The RCA was ligated proximal to the anastomosis to avoid the string sign phenomenon. This procedure is safe and fast and can be considered an alternative to coronary reconstruction.

Anomalous origin of right coronary artery from pulmonary artery presenting as chest pain in a young man.

Project description:Isolated anomalous origin of right coronary artery is a rare developmental anomaly which is mostly asymptomatic and is discovered incidentally. We present a case of a 21-year-old male who presented with chest pain and was found to have anomalous origin of right coronary artery from pulmonary artery for which he underwent prompt surgical correction.

Anomalous right coronary artery originating from the mid left anterior descending artery.

Project description:A 68-year-old male with a history of hypertension and hypercholesterolemia presented with recurrent episodes of chest discomfort. A 12-lead ECG and an echocardiogram were normal. A myocardial perfusion study could not rule out ischemia in the inferior wall. At coronary angiography using the transradial approach, the right coronary artery (RCA) could not be visualized. Angiography of the left coronary system demonstrated non-obstructive atherosclerosis involving the mid segment of the left anterior descending (LAD) artery and a normal circumflex (Cx) artery. The RCA originated from the mid LAD segment distal to the first septal perforator and the first diagonal branch and was free of atherosclerosis disease. A contrast-enhanced 64-slice multi-detector cardiac computed tomography showed that the LAD was severely calcified in the proximal part, and the RCA coursed anterior to the right ventricular outflow tract (RVOT) to reach the right atrioventricular groove. The patient was managed medically and became asymptomatic.
