Anomalous origin of the left coronary artery from the pulmonary artery: A surgical certainty

Area of Science:

• Cardiovascular Surgery
• Pediatric Cardiology
• Congenital Heart Disease

Background:

• Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital heart defect.
• Early diagnosis and surgical intervention are critical for improving outcomes in ALCAPA patients.

Purpose of the Study:

• To evaluate the clinical presentation of ALCAPA.
• To assess the outcomes of surgical correction, specifically coronary reimplantation, for ALCAPA.

Main Methods:

• Retrospective review of six ALCAPA patients undergoing surgery at Aga Khan University Hospital.
• Analysis of pre-operative and post-operative clinical features and left ventricular ejection fraction (LVEF).

Main Results:

• Common presenting features included dyspnea, palpitations, and mitral regurgitation.
• All patients underwent successful coronary reimplantation; one required mitral valve repair.
• Post-operative LVEF improved, and mitral regurgitation decreased in most patients.

Conclusions:

• Surgical correction of ALCAPA via coronary reimplantation yields favorable clinical outcomes.
• This surgical approach significantly reduces ALCAPA-associated morbidity and mortality.
