Amer M, et al. - Researchers evaluated the safety as well as haemodynamic performance of the suture-less aortic valve prostheses in order to determine their advantages as a viable alternative to current established measures, via this meta-analysis. They explored six electronic databases from inceptions to February 2017. Relevant investigations employing commercially accessible suture-free valves to substitute the aortic valve have been identified. They found 24 studies involving 5,073 patients undergoing suture-less aortic valve replacement, for inclusion in qualitative and quantitative analyses. At the 30-day and 12-month follow-ups, the mortality incidence were estimated to be 2.5% and 2.7%, respectively, while acceptable incidences of thromboembolic events (1.6%) and paravalvular leak (0.5%) were reported. As per current available evidence, it is safe to perform sutureless aortic valve replacement as it afforded low mortality and complication rates and displayed satisfactory haemodynamic performance.
