Total arch replacement in octogenarians.

OBJECTIVES

We investigated the effect of a preoperative age ≥80 years on postoperative outcomes in patients who underwent isolated elective total arch replacement using mild hypothermic lower body circulatory arrest with bilateral antegrade selective cerebral perfusion.

METHODS

A total of 140 patients who had undergone isolated elective total arch replacement between January 2007 and December 2020 were enrolled in the present study. We compared postoperative outcomes between 30 octogenarian patients (≥80 years old; Octogenarian group) and 110 non-octogenarian patients (≤79 years old; Non-Octogenarian group).

RESULTS

Overall 30-day mortality and hospital mortality were 0% in both groups, and there was no significant difference in overall survival between the 2 groups (log-rank test, P = 0.108). Univariable Cox proportional hazard analysis showed that age as continuous variable was only the predictor of mid-term all-cause death (hazard ratio 1.08, 95% confidence interval 1.01-1.16; P = 0.037), but not in the Octogenarians subgroup (P = 0.119).

CONCLUSIONS

Preoperative age ≥80 years is not associated with worse outcomes postoperatively after isolated elective total arch replacement with mild hypothermic lower body circulatory arrest and bilateral antegrade selective cerebral perfusion.
