Anomalous left coronary artery from the pulmonary artery as the cause of sudden cardiac arrest in an adult patient

We present the case of a 36-year-old male with the anomalous origin of the left coronary artery from the pulmonary artery surgically corrected in childhood who has suffered from sudden cardiac arrest twice later in life. Anomalous left coronary artery from the pulmonary artery is a rare congenital abnormality most commonly manifesting itself in early infancy, less frequently only becoming apparent in adulthood. Uncorrected defect is associated with a high mortality rate hence surgical treatment is advisable, both in children and few asymptomatic adults. Adequate management of adult patients with anomalous left coronary artery from the pulmonary artery remains a subject of discussion as complications secondary to even a congenital anomaly corrected in childhood, such as myocardial scarring, could ultimately lead to life-threatening ventricular arrhythmias and/or sudden cardiac death.
