ABSTRACT
PURPOSE: This study aimed to assess perioperative features, early postoperative outcomes, and mid-term cardiac function in children with anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) undergoing surgical repair.
METHODS: A retrospective review of 23 patients treated surgically between 2007 and 2023 was conducted. Patients were categorized into infants (<1 year) and older patients (>1 year). Clinical, operative, and echocardiographic data were analyzed, including left ventricular ejection fraction (LVEF) and mitral regurgitation (MR). Follow-up evaluations were performed at 1 and 6 months postoperatively.
RESULTS: The median age at surgery was 9 months. Early mortality occurred in 17.4%, with no late deaths during follow-up. Preoperative LVEF was significantly lower in infants than in older patients (p = 0.013). Among 19 survivors, LVEF improved markedly by 1 month and normalized in all patients by 6 months. MR was present in 89.5% preoperatively, with 47.3% showing moderate to severe grades. At 6 months, MR improved in most cases, with only 2 patients exhibiting residual moderate regurgitation and no severe cases.
CONCLUSIONS: ALCAPA is a rare but surgically correctable condition. Early surgical intervention leads to significant recovery of ventricular function and regression of MR within the first 6 postoperative months.
