Key result
Sutureless aortic valve replacement yields ~2% 30-day mortality in a pooled meta-analysis.
Why the study?
Sutureless aortic valve replacement aims to reduce cross-clamp and CPB duration and improve surgical outcomes, but its safety and efficacy require systematic evaluation.
Comparison
Sutureless AVR versus conventional AVR
Design
Systematic review and meta-analysis of observational studies

Low mortality and PVL rates support sutureless AVR consideration in high-risk patients; extends pooled evidence for its safety in aortic valve surgery.
Meta-Analysis
Phan et al. (2015) conducted a meta-analysis in Aortic stenosis. Sutureless aortic valve replacement (SU-AVR) vs. Conventional approach was evaluated on 30-day mortality. Sutureless aortic valve replacement demonstrated pooled 30-day and 1-year mortality rates of 2.1% and 4.9%, respectively, with a 3.0% incidence of paravalvular leaks.
