Cavo-atrial tumor resection under total circulatory arrest without a sternotomy.

Surgical management of intracardiac tumors arising in the inferior vena cava often requires total circulatory arrest for safe and adequate resection. Total circulatory arrest has traditionally been accomplished by accessing the great vessels through a sternotomy. Combination of a sternotomy and a large abdominal incision results in excellent exposure but also creates the potential for significant morbidity. We report here the resection of cavoatrial tumors by achieving total circulatory arrest through femoral arterial and venous cannulation without requiring a sternotomy. This minimal-access total circulatory approach has the potential to greatly diminish morbidity when managing tumors of the inferior vena cava.
