Multicentre, propensity-matched study to evaluate long-term impact of implantation technique in isolated aortic valve replacement on mortality and incidence of redo surgery

The authors report on the differences in outcome after semicontinuous versus interrupted suture techniques for aortic valve implantation. In a propensity matched analysis with 411 patient pairs they found similar mortality and the risk of redo surgery regardless of the implantation technique. The advantage of semicontinuous sutures were shorter operation times and larger valve sizes.
