Rare Incidental Finding on Coronary Artery CT Angiography: Left Main Coronary Artery Atresia

Coronary artery anomalies are usually an incidental finding on coronary angiogram. Most of them are benign, although few of them are malignant which may cause sudden cardiac death. A 64-year-old diabetic, hypertensive man underwent coronary angiography for evaluation of exertional dyspnoea, and angina which revealed an anomalous left main coronary artery (LMCA) arising from right coronary sinus which was unduly long (79 mm) but free from any disease. To the best of our knowledge after extensive search in literature, this is the longest LMCA to be ever reported. The patient was managed conservatively.

Infarction Heart

Anomalous origin of the left main coronary artery from the pulmonary artery (ALCAPA) is a rare congenital coronary anomaly with high mortality. It is associated with cardiovascular complications and is usually diagnosed soon after birth. Those who survive into adulthood can present with signs of myocardial infarction, heart failure, mitral regurgitation, severe pulmonary hypertension, or sudden cardiac death. We present a 53-year-old female presenting with atrial fibrillation and found to have an incidental diagnosis of ALCAPA who refused surgical correction. We also review the epidemiology, diagnosis, age-based clinical presentations, and treatment options for ALCAPA.
