Complicated acute type A aortic dissection and severe aortic atherosclerosis predict early mortality after frozen elephant trunk procedure.

ABSTRACT:

Objectives

To analyse risk factors for early mortality and long-term survival including secondary distal aortic interventions in patients undergoing frozen elephant trunk surgery.

Methods

A retrospective single-centre study was conducted, including all 222 patients who underwent frozen elephant trunk surgery between 2010 and 2022. We used multivariable regression analysis to detect risk factors for early mortality and Kaplan-Meier analysis for long-term survival and secondary interventions. We introduce the term 'complicated acute type A dissection' for those patients in whom the dissection was complicated by malperfusion syndrome, aortic rupture, pre-hospital intubation or resuscitation.

Results

Thirty-day mortality decreased significantly from 18.9% using the conven
