Background:
The right anterior mini-thoracotomy (RAMT) approach has become a popular technique in cardiac surgery and applied in valve surgery. However, there is very limited evidence on the application of RAMT in the Bentall surgery. In the present study, we aimed to evaluate the safety and feasibility of the RAMT approach in Bentall surgery.
Methods:
A retrospective analysis was performed on 27 patients who underwent Bentall surgery between September 2020 and April 2022 in the First Affiliated Hospital of Xi'an Jiaotong University. Follow-ups were undertaken 1 and 6 months after their operations. The baseline, perioperative, and follow-up results were retrospectively analyzed.
Results:
A total of 27 male patients aged 48-61 years were included in the study. The operation time ranged from 4.0 to 5.0 hours, with a median of 4.5 hours. The median aortic cross-clamping time was 122 minutes [interquartile range (IQR): 109-145 minutes], and the median cardiopulmonary bypass (CPB) time was 156 minutes (IQR: 143-183 minutes). The median intensive care unit stay was 3 days (IQR: 1.75-4.25 days). The ventilation time ranged from 6.5 to 22.0 hours, with a median of 13.0 hours. The median drainage volume in the first 24 hours was 210 mL. In the following-up data, no deaths or severe complications were observed.
Conclusions:
The mini-Bentall procedure through an RAMT approach is a feasible and safe approach with few wounds and good clinical results in patients undergoing aortic root replacement.
