  Abstract From January 1986 to June 1993, twenty one patients aged 70 years or older with valvular heart disease underwent open heart surgery. There were 12 males and 9 females with a mean age of 71.2 years (range 70 to 76). Eight patients were in NYHA class III, and 4 in class IV preoperatively. AVR was performed in 10 patients, MVR, MVR with TAP, OMC, AVR with MAP, DVR with TAP in 4, 4, 1, 1, and 1, respectively. Mechanical and bioprosthetic valves were replaced in 11, and 9 patients respectively. There were 6 early death (4 operative, 2 hospital). Longer duration of cardiopulmonary bypass (p < 0.05) and aortic crossclamp time (p < 0.05) were the risk factors independently for early mortality. Follow-up of 15 hospital survivors was 100% (8 months-7.7 years, mean: 3.2 years) and cumulative follow-up was 47.6 patients years (PY). There was one late death, and one prosthetic valve endocarditis (2.1%/PY). No other valve-related complications was occurred. Actuarial survival rate and freedom from valve-related morbidity at seven years were 83.3%, and 93.3%, respectively. These results show that operative mortality of valvular disease in elderly patients remains high, but the late results is acceptable one. Valve surgery for these elderly patients is reasonably acceptable.
