title: New surgical repair for an anomalous origin of the left coronary artery adjacent to the pulmonary cusps with numerous large side branches.
abstract: A new surgical procedure for anatomical correction of an anomalous origin of the left main coronary artery (LCA) from the pulmonary artery is described for those patients in whom the origin of the LCA is located adjacent to a pulmonary cusp and several side branches are arising immediately behind the ostium of the LCA. Hence the LCA can not be disconnected from the pulmonary artery for either coronary arterial transfer or bypass grafting. A tunnel-type repair may interfere with the movement of the pulmonary leaflets. In those cases our proposed surgical correction consists of an arteriotomy of the pulmonary trunk, end-to-end anastomosis of a vein graft to the ostium of the LCA and its implantation into the ascending aorta. The resulting defect in the pulmonary artery is closed with a pericardial patch avoiding kinking or stenosis of the pulmonary trunk.
