Valve surgery in elderly patients 70 years or older: early and late results.
Between April 1986 and March 1997, 75 patients (Group E) who were 70 years or older underwent valvular operations, and another 73 patients who were under 70 years constituted a comparison group (Group Y). Valve replacement was performed on 131 patients (Group E; 65 patients, Group Y; 66 patients), reparative procedures on 11 patients (Group E; 7, Group Y; 4), and aortic root replacement on 5 (Group E; 3, Group Y; 2). Coronary artery bypass grafting was concomitantly performed on 13 patients (Group E; 7, Group Y; 6). In the elderly patients, preoperative clinical status, including cardiac and non cardiac organ functions, was not necessarily more severe than that in the younger patients, however, perioperative restoration of cardiac and pulmonary functions required a longer time in Group E than Group Y. There were no significant differences in operative mortality rate, long-term survival rate, the probability of freedom from all events related to native and prosthetic valves, and in activity of daily life between Group E and Group Y. These results suggest that valvular operation for elderly patients 70 years or older may be safely performed with operative risks similar to those of younger patients by application of modern surgical techniques.
