Complete aortic root replacement in patients with small aortic annulus.
BACKGROUND
We evaluated the effectiveness of our surgical method using a modified self-assembled valved composite graft in patients with a narrow aortic annulus.


METHODS
Between August 2000 and May 2001, 10 consecutive patients with a narrow aortic annulus underwent replacement of the aortic valve and the ascending aorta using a valved composite graft with mechanical valve prosthesis. The indication for surgery was aneurysm of the ascending aorta (8 patients) and aortic dissection (2 patients). To avoid valve-patient mismatch, a modified self-assembled valved composite graft was used.


RESULTS
There was no hospital mortality. Echocardiographic evaluation before discharge showed excellent hemodynamics with a mean transvalvular gradient of 10.7 mm Hg (standard deviation +/- 2.8 mm Hg).


CONCLUSIONS
The described valved composite graft offers very good hemodynamic performance and is a simple and effective device to avoid valve-patient mismatch in patients with a small aortic annulus who need aortic root replacement.
