Minimally invasive endoscopic repair of atrial septal defects via right minithoracotomy.

Abstract

Atrial septal defect (ASD) repair has been conventionally performed via midline sternotomy with very low operative risk and excellent early and late outcomes. Recently, many of these patients with suitable anatomy are being treated with percutaneous catheter-based closure of their ASD, but issues of prosthetic device implantation, long-term antiplatelet therapy and late device complications persist. Minimally invasive repair of ASD via a 3-cm right minithoracotomy provides patients with a much less invasive surgical repair with all the durable benefits of autologous pericardial patch closure. However, widespread adoption of the minithoracotomy approach to ASD closure remains slow. This study describes the simple steps to ASD repair via a right minithoracotomy.
