Repair of secundum atrial septal defect: limiting the incision without sacrificing exposure

A simple and effective technique for repair of secundum atrial septal defect is described. The heart is exposed through a limited midline skin incision and partial sternotomy, and the atrial septal defect is closed through a right atriotomy with ascending aortic and dual venous cannulation. This approach achieves a cosmetically superior result with standard instrumentation and cardiopulmonary bypass techniques, without compromising exposure or using peripheral incisions.
