Elective aortic and mitral valve surgery in patients over 70 years of age

The results of elective cardiac surgery carried out between 1970 and 1975 on 29 patients over 70 years of age are reported. Operative mortality was 10%, late cardiac mortality 14%, with 72% survival at a mean follow-up of 38.6 months. Before operation 96% were in functional classes 3 and 4. After operation 90.5% of late survivors were in functional classes 1 and 2 at a mean follow-up of 43.5 months. These results compare favourably with those in younger patients. Complication rate and length of hospital stay were unremarkable. The risks of neurological damage and of long-term anticoagulation are not increased. Emergency surgery carries a very high risk in this age group. The importance of biological youth and good left ventricular function is emphasised. For aortic stenosis at least prognosis is improved by surgery.
