title: [Atresia or congenital stenosis of the left coronary ostium. Myocardial revascularization in 5 children].
abstract: Five patients, 3 months to 13 year old with atresia (4) or stenosis (1) of the left coronary artery underwent myocardial revascularisation at Marie Lannelongue Hospital. The preoperative symptoms were dominated in one case by cardiac failure due to myocardial infarction and in the other cases by effort angina with syncope. The operative technique of revascularisation in one case was angioplasty with enlargement of the left main coronary artery with a patch and, in the others, bypass graft of the left coronary artery with the left internal mammary artery. All 5 patients survived surgery and are asymptomatic with a follow-up of 6 months to 7 years. Control coronary angiography confirmed the patency of the different procedures of myocardial revascularisation. In 3 children, exercise electrocardiography was normal. Myocardial revascularisation of a child with a congenital stenotic abnormality of the left coronary network is possible, the technique of which depends on the diameter of the left main stenosis when the vessel is absent or atresic, left internal mammary artery bypass graft is the only solution. When the left main coronary is stenosed but patent, direct reconstructive surgery is an interesting alternative.
