abstract = {Background: Retrospective compared the results of root reconstruction and root replacement for acute type A aortic dissection ( ATAAD) patients and observed the rate of aortic insufficiency (AI) and aortic root dilation in the midterm follow-up period.
Methods: From 2008–2016, 427 ATAAD patients received surgical therapy in our center. There were 328 male and 99 female patients, aging from 22 to 83 years with a mean age of (51.1±12.5) years. These patients were divided into two major groups: 298 cases with root reinforcement reconstruction (Root Reconstruction), 129 cases with Bentall procedure (Root Replacement).
Results: The 30-day mortality was 7.7% (33/427), while no difference between the 2 procedures (8.1% and 7.0%, P=0.844). Cross-clamp, cardiopulmonary bypass, and circulatory arrest times of all the patients were 252.5±78.1, 173.6±68.9, 30.7±9.5 minutes, respectively. In the average follow-up time of (34.5±26.1) months, midterm survival rates were similar between the 2 procedures (86.2% and 86.0%, P=0.957). Only one patient received redo Bentall procedure because of severe aortic regurgitation and dilated aortic root (50 mm) in the Root Reconstruction Group.
Conclusions: The indication of root management of ATAAD is based on the diameter of aortic root, structure of aortic root, and the dissection involvement. For most ATAAD patients, aortic root reinforcement reconstruction is a feasible and safe method.},
