Severe baffle leak after Takeuchi repair successfully treated with coronary bypass and percutaneous baffle closure: a case report

BACKGROUND: Anomalous left coronary artery from the pulmonary artery is a rare congenital abnormality that requires surgical correction. CASE SUMMARY: We describe the case of a 33-year-old female with a history of anomalous left coronary artery of the pulmonary artery who presents with exertional angina. She underwent a Takeuchi repair that was complicated by a baffle leak. She was successfully treated with left internal mammary artery-left anterior descending (LAD) bypass grafting and percutaneous baffle leak closure. DISCUSSION: The Takeuchi procedure involves the creation of an aortopulmonary window and an intrapulmonary tunnel that ‘baffles’ the aorta to the ostium of the anomalous left coronary artery. The most common late complication of the Takeuchi procedure is the presence of a baffle leak. Percutaneous baffle leak occlusion via vascular plug and coronary bypass of the LAD can successfully treat a baffle leak with excellent short-term follow-up.
