Aortic Root Surgery

PinnacleHealth surgeons perform advanced aortic root surgery, with or without preserving the aortic valve. The valve sparing surgery is also known as the David procedure.

What is an aortic root aneurysm?

The aortic root is the portion of the aorta just above the aortic valve. An aortic root aneurysm is a weakening in the wall of the aorta. When an aneurysm is located in the root, it is impossible to treat the aneurysm without also treating addressing the valve.

What is the David procedure?

The diseased section of the aorta can be removed, while preserving the aortic valve. This is called the David procedure. In this valve-sparing aortic root replacement procedure, the surgeon removes the ascending aorta and coronary arteries are removed just above the aortic valve, and a synthetic graft is attached with small stitches. The coronary arteries are also reattached to the synthetic graft. This eliminates the need to replace the valve with a mechanical valve.

An advantage to the valve-sparing aortic root replacement procedure is that the patient does not need anticoagulants, or blood-thinning medications. The synthetic graft is very durable, and the patient's own aortic valve functions normally.
