Transcatheter closure for baffle leak after Takeuchi repair of anomalous left coronary artery from the pulmonary artery: a case report

INTRODUCTION: Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a rare but serious congenital coronary abnormality, Takeuchi repair is an alternative treatment option for this anomaly in certain situations, it is reported that baffle leak is the most common complication after Takeuchi repair, and some of this complication require surgical reoperation. CASE PRESENTATION: In this case, a 43-year-old woman diagnosed with ALCAPA underwent Takeuchi procedure 6 months ago, 4 months after the procedure, the patient complained of chest pain on exertion and was confirmed to have baffle leak, and then we treated this complication successfully by percutaneous transcatheter closure. DISCUSSION: Baffle leak is the most common complication after Takeuchi procedure of ALCAPA, some of them require surgical reoperation. In this case, we introduce a new method, percutaneous transcatheter closure, to treat the baffle leak. To our knowledge, this is the first reported case of transcatheter closure for baffle leak after Takeuchi repair, which may be an alternative treatment option for the baffle leak after Takeuchi repair of this rare congenital coronary anomaly.
