A surgical method for the implantation of a mechanical right ventricular assist device which avoids resternotomy/thoracotomy and related complications at the time of explantation is presented. In order to support the failing right heart, a Dacron vascular graft was sewn to the pulmonary artery. For venous drainage, a cannula was inserted into the right atrium via the femoral vein. Explantation of the system, after the right heart resumed its function, was accomplished by retracting and compressing the venous cannula in the groin as well as by retracting the arterial cannula from the Dacron vascular graft followed by suturing without opening the chest. Between 2006 and 2011, this system was used in 12 patients. The median duration of right heart support was 10.5 days. Seven patients were successfully weaned from the system, six patients survived. In all cases, explantation was free of complications. The technique described is a safe method to support the right heart and allows explantation without the risks and complications of reopening the thorax.
