Reimplantation Technique: A New Approach to Increase Aortic Valve Coaptation.

ABSTRACT

The reimplantation technique is one of the most popular valve-sparing procedures. Previously published in-vitro studies have demonstrated the success of the aortic interleaflets triangle reshaping approach in increasing the coaptation surface. An alternative positioning of the pledgeted stitches used in the proximal suture line of the David operation is proposed to simultaneously stabilize the annulus and improve the valve functional reserve in case of annulo-aortic ectasia due to dilation of the interleaflet triangles.
