Novel Expansible Aortic Annuloplasty Ring Exhibits Similar Characteristics as the Dacron Ring-an In Vitro Evaluation.

An increasing body of research indicates that annular stability plays a key role for a successful aortic valve repair. The aim of this study was to evaluate and compare a novel open aortic annuloplasty ring (the A-ring) with the Dacron ring. Both rings were compared with native aortic roots in vitro.
