3D-video- and robot-assisted minimally invasive ASD closure using the Port-Access techniques.

Abstract

BACKGROUND: Video-assisted minimally invasive surgical methods with endovascular-based femoral cardiopulmonary bypass (CPB) and balloon occlusion of the aorta (Port-Access technique) were used to close an ostium-secundum atrial septal defect (ASD) in 7 patients. METHODS: Minor modifications were made to the system to provide drainage of the superior vena cava. The surgery was performed through a small (3.5-5cm) right anterolateral thoracotomy with 3D video and robotic arm assistance. RESULTS: The operative procedures were completely uneventful and the patients were discharged four days postoperatively in good condition and with excellent cosmesis. CONCLUSION: Using the modifications described, the Port-Access surgical method can be recommended for minimally invasive closure of an ASD.
