OBJECTIVE: Sutureless aortic valve prostheses are anchored by radial force in a mechanism similar to that of transcatheter aortic valve implantation. Transcatheter aortic valve implantation is associated with an increased permanent pacemaker (PPM) requirement in a significant proportion of patients. We undertook a meta-analysis to examine the incidence of PPM insertion associated with sutureless compared with conventional surgical aortic valve replacement. METHODS: A systematic review was conducted in accordance with the Prisma guidelines. All searches were performed on August 10, 2014. Studies between 2007 and 2014 were included in the search. RESULTS: A total of 832 patients were included in the sutureless group and 3,740 in the conventional group. Aortic cross-clamp (39.8 vs 62.4 minutes; P < 0.001) and cardiopulmonary bypass (64.9 vs 86.7 minutes; P = 0.002) times were shorter in the sutureless group. Permanent pacemaker implantation rate was higher in the sutureless cohort (9.1% vs 2.4%; P = 0.025). CONCLUSIONS: Sutureless aortic valve prostheses are associated with significantly shorter cardiopulmonary bypass and aortic cross-clamp times and a higher incidence of PPM insertion than conventional. Further investigation of the prognostic significance is required.
