Key result
This is a study protocol for a retrospective analysis of risk factors for perioperative mortality in patients undergoing aortic valve replacement with biological valves; no results are reported.
Why the study?
Perioperative deaths remain elevated in China among patients undergoing AVR with biological valves, and measures to reduce this mortality are needed.
Population
Patients undergoing AVR surgery with biological valves at Affiliated Hospital of Qingdao University
Comparison
Perioperative death group vs survival group
Design
Retrospective cohort study

Protocol offers no results on biological AVR mortality risks; leaves open identification of perioperative predictors for future analysis.

This retrospective study aims to identify risk factors for perioperative mortality in patients undergoing biological aortic valve replacement to guide clinical decision-making.
Li et al. (2020) conducted an observational in Aortic valve disease requiring aortic valve replacement (n=110). Risk factors for perioperative mortality vs. Survival group was evaluated on Perioperative mortality and associated risk factors (including preoperative NYHA class, operation time, surgical approach, aortic occlusion time, etc.). This is a study protocol for a retrospective analysis of risk factors for perioperative mortality in patients undergoing aortic valve replacement with biological valves; no results are reported.
