A Case Of Pediatric Heart Failure Caused By Anomalous Origin Of The Left Coronary Artery From The Pulmonary Artery: Case Report And Literature Review

A female patient aged 3 months and 10 days was admitted to the cardiology department because of symptoms of heart failure. According to the echocardiography results, the patient received a diagnosis of primary endocardial fibroelastosis and was treated with gamma-globulin, prednisone, digoxin, and diuretics. Coronary computed tomographic angiography and coronary angiography were performed as there was no improvement after 2 months of treatment. Finally, the patient received a diagnosis of anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA). ALCAPA is a rare congenital heart defect that can cause severe heart failure during infancy, and is easily misdiagnosed clinically. In this report, we show the process of misdiagnosis of the case and consult the relevant literature, hoping to improve the understanding and early diagnosis of ALCAPA.
