Abstract:

Objective A single-center analysis of the efficacy of David I versus Bentall procedure for acute aortic dissection was conducted. Methods A total of 28 patients with acute aortic dissection hospitalized in the Department of Cardiovascular Surgery, the First Affiliated Hospital of Zhengzhou University from January 2020 to December 2022 were enrolled. According to the surgical methods, they were divided into David I group (n=13, received David I procedure ) and Bentall group (n=15, received Bentall’s procedure). After 1 year of follow-up, the inter-group perioperative indexes, cardiac indexes and complications were assessed. Results The operation time, transfer time and aortic occlusion time were significantly longer in David I group versus Bentall group (P<0.05). There were no significant differences in intraoperative blood loss, 24 h postoperative drainage volume, ventilator-assisted time, intensive care unit stay time, and hospitalization time in David I group versus Bentall group (P>0.05). There was no significant inter-group difference in left ventricular ejection fraction (LVEF), maximum diameter of ascending aorta and left ventricular end-diastolic diameter (LVDD) before operation and on year 1 of operation (P>0.05). LVEF in David I group was significantly decreased on year 1 of operation than that before operation (P<0.05), and maximum diameter of ascending aorta and LVDD were significantly decreased on year 1 of operation in the both groups than those before operation (P<0.05). There was no inter-group significant difference in the incidence of complications (46.1% vs 46.7%, P>0.05). Conclusion There was no significant difference in postoperative survival rate and valvular complications between Bentall and David Ⅰ procedure in the treatment of acute aortic dissection. The Bentall procedure has a shorter operating time, transit time, and aortic occlusion time.
