Abstract Background Anomalous origin of the coronary arteries is seen in less than 1% of the general population. Single coronary artery (SCA) is a congenital anatomic abnormality identified by a single coronary ostium giving rise to one coronary artery. We present an extremely rare variant of the left main coronary artery (LMCA) branching off from the right coronary artery (RCA) and following a prepulmonic course. Case summary A 72-year-old woman presented due to ongoing chest pain with associated ST-segment elevation involving the inferior leads. Emergent cardiac catheterization revealed a 99% ulcerated lesion in distal RCA, which was intervened on with angioplasty and stent placement. The RCA was noted giving rise to LMCA, which followed a prepulmonic course (anterior to pulmonary artery) before trifurcating into a small caliber left anterior descending, ramus intermedius, and hypoplastic left circumflex arteries. The non-malignant course of the aberrant LMCA was confirmed on the coronary computed tomography angiogram. The patient was discharged home on guideline-directed medical therapy. Discussion The patient illustrated congenital SCA with type RIIA pattern of the aberrant vessel based on the Lipton anatomic classification for SCA. The prepulmonic course of SCA is usually benign and can be managed conservatively.

Anomalous origin of the coronary arteries is a very rare phenomenon and is seen only in less than 1% of the general population. Single coronary artery (SCA) is a congenital anatomic abnormality identified by a single coronary ostium giving rise to one coronary artery. Our case presented at 40 years with intermittent chest discomfort, effort intolerance and a history of getting Streptokinase one month back due to AMI (Inferior). Diagnosis was confirmed with elective conventional coronary angiography and coronary CT angiography as an extremely rare variant of the left main coronary artery (LMCA) branching off from the right coronary artery (RCA) and then following a pre-pulmonic course. We did Off Pump CABG surgery with four grafts and discharged the patient uneventfully with guidelinedirected medical therapy with a beta-blocker, statin, and dual antiplatelet agents and the patient is on follow up.

The Impact

Abstract Introduction Total occlusion of the left main coronary artery is a very rare finding in coronary angiography because of its highly lethal nature. Right coronary artery dominance and extensive collateral circulation are the principal determinant factors of survival after total occlusion of the left main coronary artery. The impact on the left ventricle is often significant with a profound alteration of its systolic function. Case presentation We describe a 52-year-old North African man, a tobacco smoker, who presented symptoms of unstable angina related to a total chronic occlusion of his left main coronary artery with a right coronary artery stenosis. Unexpectedly, the impact on his left ventricle was absent with normal dimensions and systolic function. He underwent a successful on-pump coronary artery bypass grafting with uneventful postoperative course and good recovery. Conclusions Total occlusion of the left main coronary artery is a rare condition, the fact that the left ventricle retains a normal size and systolic function makes it exceptional, which must be kept in mind to avoid dangerous examinations and delayed treatment. Coronary artery bypass surgery should be considered the main treatment of total chronic occlusion of the left main coronary artery.
