Operative and middle-term results of cardiac surgery in nonagenarians: A bridge toward routine practice

Background: Age >90 years represents in many centers an absolute contraindication to cardiac surgery. Nonagenarians are a rapidly growing subset of the population posing an expanding clinical problem. To provide helpful information in regard to this complex decision, we analyzed the operative and 5-year results of coronary and valvular surgical procedures in these patients. Methods and Results: We retrospectively reviewed 127 patients aged ≥90 years who underwent cardiac surgery within our hospital group in the period 1998 to 2008. Kaplan-Meier and multiple logistic regression analyses were performed. A longer follow-up than most published studies and the largest series published thus far are presented. Mean age was 92 years (range, 90 to 103 years). Mean logistic EuroSCORE was 21.3±6.1. Sixty patients had valvular surgery (including 11 valve repairs), 49 patients had coronary artery bypass grafting, and 18 had valvular plus coronary artery bypass grafting surgery (55 left mammary artery grafts implanted). Forty-five patients (35.4%) were operated on nonelectively. Operative mortality was 13.4% (17 cases). Fifty-four patients (42.5%) had a complicated postoperative course. There were no statistically significant differences in the rate and type of complications between patient strata on the basis of type of surgery performed. Nonelective priority predicted a complicated postoperative course. Predictors of operative mortality were nonelective priority and previous myocardial infarction. Kaplan-Meier survival estimates at 5 years were comparable between patient groups on the basis of procedure performed. Conclusions: Although the rate of postoperative complications remains high, cardiac surgery in nonagenarians can achieve functional improvement at the price of considerable operative and follow-up mortality rates. Cardiac operations in these very elderly subjects are supported if appropriate selection is made and if the operation is performed earlier and electively. Our results should contribute to the development of guidelines for cardiac operations in nonagenarians. © 2010 American Heart Association. All rights reserved

Short-term and long-term results of cardiac surgery in elderly and very elderly patients

Objective: Cardiac operations in elderly patients are increasingly frequent and imply major clinical, ethical, and economic issues. Operative and 5-year results of cardiac operations in patients aged 79 years or more are known in limited series, and a debate is ongoing on the appropriateness of selection of patients for surgery. Methods: We retrospectively reviewed our experience in 6802 patients aged 79 years or more who had received a cardiac operation. Surgical candidates were selected according to functional status, crude operative risk, and social context and were managed according to a multimodality protocol. Results: Mean age was 82 years and surgery was nonelective in 1613 cases (23.5%, 31 salvage). Procedures consisted of valve replacement (aortic, 2817; mitral, 532; and tricuspid, 2 cases), valve repair (aortic, 66; mitral, 532; and tricuspid, 232 cases), coronary bypass grafting (12,034 coronary vessels bypassed), and replacement of the thoracic aorta (ascending, 315; arch, 28 cases). Overall operative mortality was 3.4%. Nonelective presentation, need for aortic counterpulsation, cardiopulmonary bypass time, blood transfusion, depressed systolic function, and chronic lung disease predicted operative mortality. Five-year cumulative mortality was 7.5%. Poor systolic function, previous myocardial infarction, and combined coronary/mitral surgery predicted late mortality. The operative risk of nonagenarians operated on electively did not differ from that of risk-matched octogenarians. Conclusions: Cardiac surgery in elderly and very elderly patients can be performed with acceptable mortality provided that accurate selection and a multifactorial risk evaluation are adopted. Whenever possible, nonelective operations should be avoided and earlier surgery should be encouraged. Five-year survival and functional recovery are good.
