Ideal site for ventricular anchoring of artificial chordae in mitral regurgitation

Surgical treatment of mitral leaflet prolapse using artificial neochordae shows excellent outcomes. Upcoming devices attempt the same treatment in a minimally invasive way but target the left ventricular apex as an anchoring point, rather than the tip of the corresponding papillary muscle. In this study, cine cardiac magnetic resonance imaging was used to compare these 2 different anchoring positions and their dynamic relationship with the mitral leaflets.

A prospective randomised trial comparing the modified HM3 with the MODULITH® SLX-F2 lithotripter

The relative efficacy of first- versus last-generation lithotripters is unknown.
