Aortic Surgery Mechanical Valve Conduit

Modified Bentall with valve conduit

The initial method to repair an aortic aneurysm and valve was described by Hugh Bentall, MD. The procedure has been modified over the years, but the essential points remain. The valve leaflets and aortic aneurysm are completely removed. A mechanical valve conduit (manufactured by either St Jude Medical or ATS Medical) is selected after appropriate sizing has been performed. The valve is sewn into the circle (annulus) remaining after the old valve was removed. The coronary arteries are reimplanted into graft. The graft is then cut to an appropriate length and sewn to the aortic arch. This procedure has been performed for over 40 years and has excellent durability. The downside is that it requires the patient to remain on anticoagulation for the rest of their life.
