Abstract

Paediatric coronary artery bypass surgery with internal thoracic artery grafting is the optimal choice for left main coronary artery atresia; we report successful reconstruction in a patient with bypass graft obstruction. The pulmonary trunk was transected to expose the left main coronary stem, which was opened beyond the obstruction and the incision extended through the left main coronary artery to the circumflex bifurcation and left anterior descending artery. A funnel-shaped coronary ostium was created with a glutaraldehyde-treated autologous pericardium onlay patch. Surgical reconstruction is a good alternative for left main coronary artery atresia with graft obstruction and preserves the remaining internal thoracic artery for future use.
