title: Coronary ostioplasty for congenital atresia of the left main coronary artery ostium.
abstract: BACKGROUND
  Coronary ostial atresia is a rare anomaly, most frequently managed with coronary artery bypass grafting. This condition is often misdiagnosed as anomalous left coronary artery from the pulmonary artery until the time of surgical intervention, leaving the surgeon little time to contemplate the best operative technique.
  
  
  METHODS
  In this single-center experience, three cases of congenital atresia of the left main coronary artery presenting during childhood were surgically managed with homograft patch ostioplasty.
  
  
  RESULTS
  Antegrade left coronary artery blood flow was successfully established in all three cases without the use of a bypass graft. Two children survived and are clinically well; the third had visibly necrotic myocardium at the time of surgical ostioplasty and did not survive to hospital discharge.
  
  
  CONCLUSIONS
  Surgical ostioplasty with a homograft patch should be considered as an alternative to bypass grafting for coronary ostial atresia in children.
