Monocusp Valves Do Not Improve Early Operative Mortality in Tetralogy of Fallot: A Meta-Analysis.

Monocusp valves are thought to reduce early operative mortality and morbidity associated with pediatric tetralogy of Fallot repair. As there are no published randomized clinical trials comparing outcomes with and without a monocusp valve, we performed a meta-analysis of observational studies in accordance with established protocols. After systematically searching PubMed, the Cochrane Library, and Google Scholar, 12 studies were included.
