摘要

Dear EditorWe are writing to you regarding a recently published article in the International Journal of Artificial Organs titled "A Pulsatile Simulator for the In Vitro Analysis of the Mitral Valve with Tri-axial Papillary Muscle Displacement," by Vismara et al. In this article, the authors describe the development of a pulsatile, in vitro flow loop with the ability to 3-dimensionally position the papillary muscles (PMs) of freshly excised mitral valves (MVs), measure the force exerted by the chordae tendineae on the PMs, and possibly visually inspect the MVs for kinematic analysis.
