Hufnagel revisited: a descending thoracic aortic valve to treat prosthetic valve insufficiency

In 1953 Hufnagel and Harvey reported their successful treatment of aortic valve insufficiency by the implantation of a ball-valve prosthesis into the descending thoracic aorta. Since then, great advances in technology, surgery, and anesthesia have made aortic valve replacement a more common procedure with relatively low mortality. This remains true for the vast majority of prosthetic valve replacements. However, cases requiring reoperation can be difficult, leading to a much higher degree of morbidity and mortality. In selected patients who require repeated approaches to the aortic root we propose that Hufnagel's original idea may still be of value to reduce the severity of aortic insufficiency. We report our experience in 4 cases of aortic prosthetic incompetence, all of which were improved by two New York Heart Association functional classes after a modification of Hufnagel's procedure.
