Abstract
Background and objectives
Sutureless aortic valves aim to achieve better outcomes and to aid and facilitate the minimally invasive aortic valve replacement procedure by tackling the issue of cross clamp time, which is an independent predictor of post-operative outcomes especially in patients with serious comorbidities. (2, 3) By reducing the number of sutures, the time for sutures placement is reduced. (1)
Our Meta-analysis tries to assess the safety and hemodynamic performance of the sutureless aortic valve prosthesis’s in an attempt to ascertain their benefits as a viable alternative to current established measures.
Methodology
From their beginnings to February 2017, electronic searches were conducted using six databases. Relevant studies using commercially accessible suture-free valves to replace the aortic valve have been recognized. Based on the predefined endpoints, data were collected and analyzed.
Results
FC For incorporation in qualitative and quantitative analyses, twenty-four studies were recognized, with a total number of 5073 patients undergoing sutureless aortic valve replacement (SU-AVR). Mortality incidence at 30 days and 12 months follow-ups were 2.5% and 2.7%, respectively, while the incidence of thromboembolic events (1.6%) and paravalvular leak (PVL) (0.5%) were acceptable.
Conclusion
Current available evidence indicates that sutureless aortic valve replacement is a safe operation showing low mortality and complication rates, with satisfactory hemodynamic performance.
