Robotic-assisted aortic valve bypass (apicoaortic conduit) for aortic stenosis.

Abstract

Aortic valve bypass (AVB [apicoaortic conduit]) surgery consists of the construction of a valved conduit between the left ventricular apex and the descending thoracic aorta. In our institution, AVB is routinely performed without cardiopulmonary bypass or manipulation of the ascending aorta or native aortic valve. We report the case of an 83-year-old man with severe symptomatic bioprosthetic aortic stenosis, chronic thrombocytopenia, and a patent bypass graft who underwent robotically assisted beating-heart AVB through an anterior minithoracotomy. The distal anastomosis was constructed entirely using robotic telemanipulation. Robotic assistance enables the performance of beating-heart AVB through a small incision.
