Aortic Surgery 
Homograft Root Replacement
A homograft (human tissue) root replacement follows the same basic steps as the David procedure, except that the aortic valve tissue is also removed.
An appropriately sized donor aorta is selected based on the measurement of the aortic annulus (ring of tissue surrounding the valve).
Since we are attached to the Morgan Stanley Children's Hospital of NewYork-Presbyterian, we retain a wide range of homograft sizes.
The donated valve is then trimmed to size and attached with a continuous suture to the heart.
The reattachment of the coronary arteries and the attachment to the aortic arch require continuous sutures as well.
