Abstract:
The Y incision and roof technique for aortic valve replacement enable implantation of a large prosthetic valve and extensive enlargement of the sinotubular junction. Surgeons have been reluctant to adopt a minimally invasive approach for this procedure because of its complexity and risk. The Stonehenge technique was designed to achieve an ideal surgical view of the aortic root through a small right thoracotomy. Herein, we report implementing a Y incision and roof technique for aortic valve replacement through a minimally invasive approach facilitated by the Stonehenge technique.
