Concomitant Aortic Root Replacement in Total Arch Replacement With Frozen Elephant Trunk for Type A Aortic Dissection: A Propensity-Weighted Analysis.

ABSTRACT:

Objectives

This study aims to evaluate the impact of concomitant aortic root replacement (ARR) on early and late outcomes in patients undergoing total arch replacement (TAR) with frozen elephant trunk (FET) for type A aortic dissection (TAAD).

Methods

From January 2010 to December 2019, a total of 1155 patients were enrolled. Among them, 325 patients received concomitant ARR (with ARR group) while 830 patients did not (without ARR group). Baseline differences were adjusted using inverse probability of treatment weighting (IPTW).

Results

After IPTW, the with ARR group still had a higher prevalence of Marfan syndrome (2.6% vs 7.3%, P = .038) and a greater proportion of patients with moderate or greater aortic insufficiency (18.1% vs 64.7%, P < .001). Cardiopulmonary byp
