Outcomes of Liu's aortic root repair and valve preservation in patients with type A dissection and aortic regurgitation.

ABSTRACT:

Objectives

To evaluate short- and medium-term outcomes following Liu's aortic root repair and valve preservation in patients with acute type A aortic dissection complicated by moderate-to-severe aortic regurgitation (AR).

Methods

From October 2011 to July 2018, a total of 324 consecutive patients underwent emergency surgery for acute type A aortic dissection. There were 122 patients (38%) with moderate-to-severe AR, of whom 82 (67%) underwent Liu's aortic root repair and valve preservation. Aortic computed tomography angiography and echocardiography were performed at discharge, 6 and 12 months postoperatively, and annually thereafter. We focused on assessing the survival and aortic root and valve durability in the 82 patients.

Results
