Anomalous origin of the left coronary artery from the pulmonary artery in an elderly patient, football player in youth.
Anomalous origin of the left coronary artery from the pulmonary artery is a rare congenital defect. Without surgical treatment, approximately 90% of infants die within the first year of life. Late presentation in the adult or elderly is rare. Factors that may lead to survival in advanced age include the development of intercoronary collaterals. Furthermore, the risk of sudden cardiac death due to ischaemic malignant ventricular dysrhythmias exists even in asymptomatic adult patients and, classically, is precipitated by exercise. We report the case of a 67-year-old man, a football player in his youth, always asymptomatic until presentation at our centre for symptomatic sustained ventricular tachycardia and shortness of breath on exertion. We show the features of the ECG, transthoracic echocardiography, angiography study of the coronary and the pulmonary system, myocardial basal and stress gated single photon emission computed tomography with Tc-tetrofosmin and cardiac CT 64 slices. The patient was referred to cardiac surgery. We believe that this patient's favourable course may be ascribed to the large network of collaterals from the right coronary artery supplying the entire heart. However, the exact reason why these favourable evolutions (both vascular and clinical) occur only in some individuals remains largely unknown.
