Reconstructive valve surgery.
Despite continued refinement of heart valve prostheses, valve replacement carries risks of thromboembolic, mechanical, and infectious complications, and long-term success is further limited by the eventual wear of prosthetic parts. In many patients with congenital or acquired valve diseases, valve function may be improved, if not restored, by reconstructive techniques, prosthetic replacement being thereby avoided or delayed. This review examines the current status of reconstructive procedures for management of diseased valves, with emphasis on long-term results and post-operative hemodynamic studies. In many instances the choice between reconstruction and replacement of a diseased valve remains controversial. The documented success of selectively applied reconstructive techniques, however, weighs against expedient decisions for prosthetic replacement and supports a continuing search for new techniques.
