Abstract:
Objective To evaluate the outcome of valvular surgery in the elderly. Methods Between 1993 and 2004, 4546 patients underwent cardiac valve operation at our hospital. 252 patients (5.5%)(147 males, 105 females) were 65 or older [mean age (67.9?2.9) years]. Rheumatic valvular disease presented in 201(79.8%) patients and non-rheumatic valvular disease in 51 (20.2%). 56.0% of patients were in New York Heart Association (NYHA) functional class Ⅲ-Ⅳ.63 (25%) patients had aortic valve replacement (AYR), 93 (36.9%) had mitral valve replacement (MVR), 42 (16.7%) had mitral valve repair (MVP), 47 (18.7%) had AVR + MVR/MVP, and 7 (2.8%) had isolated tricuspid repair or replacement.34 (13.5 % ) had concomitant coronary artery bypass grafting (CABG) . Results Results The operative mortality was 9.1%, and the tendency of decline was observed in recent 3 years. As compared with the patients aged 16 to 64 years, the duration of mechanical ventilation, stay in ICU and in hospital postoperatively was longer [(30.6?42.8)h vs. (24.1?45.0) h,P = 0.02, (60.1?101.2) h vs. (43.0?70.6) h, P = 0.00, (25.7?41.3) days vs. (19.6?14.4) days,P=0.00]. In this group, the morbidity of postoperative complications was significant higher than that of the patients aged 16 to 64 years (10.6% vs.6.4% , P = 0.01). Preoperative NYHA function class was an important factor for postoperative mortality. Multivariate logistic regression showed that concomitant coronary artery bypass grafting (CABG) , AVR+ MVR/MVP, and prolonged cardiopulmonary bypass time, prolonged aortic cross-clamping time, postoperative acute renal failure demanding dialysis were significant independent predictors of operative mortality. Conclusion The mortality of cardiac valvular surgery in the elderly is acceptable. It is characterized by higher morbidity of postoperative complications and prolonged duration of stay in hospital. Concomitant CABG, AVR + MVR/MVP, prolonged cardiopulmonary bypass time, prolonged aortic crossclamping time and postoperative acute renal failure were significant independent predictors of operative mortality.
