Abstract:
Three-patch repair of supravalvar aortic stenosis is a widely accepted surgical approach for this congenital heart lesion. We describe an unusual complication of this approach, which resulted in ischemia in the left anterior coronary artery distribution. Subtle oversizing of the left sinus of Valsalva patch led to kinking of the origin of the left anterior descending artery; the circumflex artery was not affected. Sinus of Valsalva reconstruction and reimplantation of the left coronary button restored normal coronary perfusion.
