Abstract

OBJECTIVE:

This study was planned to evaluate the outcome of patients ≥80 years old undergoing isolated conventional aortic valve replacement (AVR).

METHODS:

Systematic review of the literature and meta-analysis of data on octogenarians and nonagenarians who underwent isolated AVR were performed.

RESULTS:

The literature search yielded 48 observational studies reporting on 13 216 patients ≥80 years old. Pooled proportion of immediate postoperative mortality was 6.7 % (95% CI 5.8-7.5, 47 studies, 13,092 patients), and it was 5.8% (95% CI 4.8-6.9) in 18 studies with a mid-date from 2000 to 2006 and 7.5% (95% CI 6.8-8.2) in 30 studies with a mid-date from 1982 to 1999 (P = .004). Pooled proportion of postoperative stroke was 2.4% (95% CI 2.1-2.7, 21 studies, 8,436 patients), that of postoperative dialysis was 2.6% (95% CI 1.6-3.8, 10 studies, 1,945 patients), and that of postoperative implantation of a pacemaker was 4.6% (95% CI 3.6-5.8, 6 studies, 1,470 patients). Pooled survival rates at 1, 3, 5, and 10 years after isolated AVR were 87.6%, 78.7%, 65.4%, and 29.7%, respectively.

CONCLUSIONS:

Immediate postoperative mortality and morbidity after isolated AVR in patients ≥80 years old are rather low. Postoperatively mortality decreased even further in the most recent series. Importantly, isolated AVR in these high-risk patients was associated with good late survival. These findings suggest that advanced age alone cannot be considered as a contraindication to conventional isolated AVR and that any new valve prosthesis implanted in these patients should be durable enough to guarantee the results so far offered by conventional surgery.
