Permanent pacemaker implantation and paravalvular leak rates following sutureless aortic valve operations.

In SuAVR prostheses implanted in this meta-analysis, the postoperative permanent pacemaker rate was higher (8.5%) than reported for non-SuAVR prosthesis. While the overall PVL rate was 4.2%, the incidence of severe PVL was only 0.4% at discharge and remained stable at 0.5% at 12 months.
