Key result
An in-vitro evaluation system successfully measured valve orifice area and tensile load to characterize the functional performance of the Duran Flexible Annuloplasty Ring.
A newly developed in-vitro system can successfully measure valve orifice area and tensile load to evaluate the functional performance of annuloplasty rings.
May enable standardized preclinical ring testing; leaves open clinical translation pending in-vivo validation.
An in-vitro system was devised to study the performance of newly developed annuloplasty rings as well as various conventional rings. The Duran Flexible Annuloplasty Ring was tested to define its characteristics and to validate the system for comparative testing. It was possible to obtain quantitative data using a microscope and a load cell to respectively measure valve orifice area and tensile load on the valve annulus. The results suggest that this apparatus could be employed to characterize the features and functional performance of other types of annuloplasty ring.
