RECONSTRUCTION OF DILATED AORTIC ANNULUS USING SHORT TUBULAR DACRON GRAFT FOR AORTIC ROOT REPLACEMENT BY AORTIC HOMOGRAFT - A SOLUTION FOR SIZE MISMATCH

To circumvent the problems associated with a dilated aortic annulus we first reduced the diameter of the annulus with a short section of Dac ron graft and then implanted a smaller size homograft within the graft . This procedure was successfully performed for complete homograft aor tic root replacement in a 25-year-old man with severe aortic insuffici ency due to a dilated aortic annulus. The indication for homograft rep lacement can thus be widened, even to patients with a dilated aortic a nnulus.
