Valve-sparing aortic root replacement

Valve-sparing aortic root replacement (also known as the David procedure) is a cardiac surgery procedure which is used to treat Aortic aneurysms and to prevent Aortic dissection. It involves replacement of the aortic root without replacement of the aortic valve. Two similar procedures were developed, one by Sir Magdi Yacoub, and another by Tirone David.
