Why the study?
Conflicting views exist regarding the status of valve-sparing root replacement as a proper treatment for acute type A aortic dissection.
Does valve-sparing root replacement improve mortality compared to the Bentall procedure in patients with acute type A aortic dissection?
Population
706 patients with AAAD undergoing aortic root surgery across 9 studies
Comparison
Valve-sparing root replacement vs Bentall procedure
Design
Systematic review and meta-analysis
Key result
Valve-sparing root replacement significantly reduced the risk of early death (OR 0.34; 95% CI 0.21-0.57) and late death compared to the Bentall procedure in acute type A aortic dissection.

May favor valve-sparing root replacement over Bentall for lower mortality in acute type A dissection; leaves open durability and RCT confirmation.
Meta-Analysis (n=706)
Does valve-sparing root replacement improve mortality compared to the Bentall procedure in patients with acute type A aortic dissection?
Odds Ratio: 0.34 (95% CI 0.21–0.57)
Valve-sparing root replacement in acute type A aortic dissection is associated with lower early and late mortality compared to the Bentall procedure, despite a higher risk of reintervention.
Wu et al. (2019) conducted a meta-analysis in Acute type A aortic dissection (AAAD) (n=706). Valve-sparing root replacement (VSRR) vs. Bentall procedure was evaluated on Early death (OR 0.34, 95% CI 0.21-0.57). Valve-sparing root replacement significantly reduced the risk of early death (OR 0.34; 95% CI 0.21-0.57) and late death compared to the Bentall procedure in acute type A aortic dissection.
