Surgical treatment of mitral valve disease: late results with valve replacement

Computer aided data processing of the results of surgery in 504 patients with mitral (and mitral + aortic + tricuspid) valvular disease, operated on by the Szeged cardiosurgery group between 1966-1983 are discussed. Late results after valve surgery are investigated from the point of view of survival time, functional state and social rehabilitation. Statistical evaluation of postoperative complications and the functional life-time of the Cross-Jones prosthesis are reported. The functional rehabilitation following the operation is mathematically assessed.
