Since the introduction of the aortoventriculoplasty procedure by Konno in
1975, 16 patients have undergone aortic root augmentation by this method at
the Woodruff Medical Center of Emory University. In four patients
bioprosthetic valve degeneration 2 to 5 years after the Konno procedure has
necessitated repeat operation and replacement of the prosthetic aortic
valve. Modification of the septal patch or repeat right ventriculotomy has
not been required. One patient required an additional lateral
anulus-enlargement procedure (Manouguian) whereas the other three have
demonstrated stability or growth of the aortic anulus. We have not observed
recurrent subvalvular stenosis or problems with the right ventricular
outflow tract. Repeat operation after aortoventriculoplasty has been
relatively simple and has usually involved only the supra-annular aorta.
