aortic root replacement
Surgical procedure replacing the entire aortic root, including the valve, sinuses of Valsalva, and ascending aorta.
Full Definition
Aortic root replacement is a comprehensive surgical procedure that involves removing and replacing the entire aortic root complex, including the aortic valve, sinuses of Valsalva, and the initial portion of the ascending aorta. This procedure is indicated for conditions affecting the entire root structure such as aortic root aneurysms, extensive aortic regurgitation with root dilatation, or complex congenital anomalies. The replacement may be performed using composite grafts (mechanical or biological valve sewn to a synthetic tube graft) or with separate valve and graft components. Coronary artery reimplantation is required, making this a technically demanding operation with specific risks related to coronary complications.
Usage
Usage note: Encompasses various specific techniques; distinguish from isolated valve or ascending aorta procedures.
