ABSTRACT
Abstract Objective: To examine the results of various myocardial revascularization techniques in pediatric patients to better understand the strategies for surgical treatment of coronary artery pathologies. Methods: We analyzed 61 publications dedicated to the indications, methods, and results of coronary bypass surgery in children. Due to the small size of this cohort, case reports are also included in our review. Results: The main indications for coronary bypass grafting in children are Kawasaki disease, myocardial revascularization as a necessary procedure during the congenital cardiac surgery, to manage intraoperative iatrogenic damage to coronary arteries, and homozygous familial hypercholesterolemia. The use of internal thoracic arteries as conduits for coronary bypass grafting in children with Kawasaki disease showed significantly better results in long-term functionality compared to autovenous conduits (87% and 44%, respectively, P<0.001). Acute and late coronary events after arterial switch operation for the transposition of the great arteries, anomalous origin of the left coronary artery from the pulmonary artery, and left main coronary artery atresia are the main congenital heart diseases where surgical correction involves interventions on the coronary arteries. Conclusion: The internal thoracic artery is a reliable and durable conduit that demonstrates proven growth potential in children.

Abstract We report a case of a 23-year-old man who was diagnosed with Kawasaki disease that progressed to a coronary aneurysm in the left main coronary artery (LMA). He had suffered from acute coronary syndrome and then underwent an emergent percutaneous coronary angioplasty, in which a polyurethane-covered stent was placed inside the aneurysm. The stent was thrombosed one year later, despite the patient had been treated with anticoagulant and antiplatelet therapy. Emergency percutaneous intervention was then performed. LMA was reopened and stent malposition was observed. Therefore, urgent coronary bypass grafting was performed in which a high degree of competitive flow was observed through the reopened stent. LMA was ligated at the inflow of the aneurysm, resulting in an improvement of graft flow. Left main ligature has not been previously reported.

La enfermedad de Kawasaki, o síndrome linfoganglionar mucocutáneo, es una patología multiorgánica infantil, de afectación preferente por las arterias de mediano y pequeño calibre y, especialmente, las arterias coronarias. Se presenta en este trabajo la resolución quirúrgica secuencial de varios aneurismas coronarios, y un aneurisma de la arteria renal izquierda, en un paciente varón de 9 años, afecto de enfermedad de Kawasaki. Los procedimientos llevados a cabo, con 6 días de diferencia fueron: Primero - Triple bypass aorto-mamario-coronario sin circulación extracorpórea (puente mamario a la descendente anterior y puentes venosos a la coronaria derecha y la circunfleja). Segundo - Ligadura - exclusión del aneurisma renal izquierdo, y bypass aorto-renal con vena safena, por vía extraperitoneal. El paciente fue dado de alta al octavo día postoperatorio de la segunda intervención, y se halla en la actualidad, dos años después, asintomático y de retorno a su vida normal
