"T-shaped" repair for commissural detachment in acute type A aortic dissection.

Aortic insufficiency in patients with type A aortic dissection is commonly seen and, in most cases, is the consequence of commissural detachment. We report our method of aortic valve repair in which the valve commissure and detached intima are repaired by using a "T-shaped" polyester patch that fits well within the aortic root after removal of the clots in the proximal false lumen. The early results have proved this is an easy and effective way to repair valve commissural detachment and reconstruct the aortic root.
