The New Era of Three-Dimensional Annuloplasty Devices for Mitral Valve Repair: Rationale and First Experiences

Mario Torre et al. Surg Technol Int. .

Abstract

Annuloplasty should always accompany mitral valve repair in order to achieve proper annular remodeling and stabilization. Numerous types of annuloplasty rings-that differ from rigid to semi-rigid and flexible devices, from complete to partial, and from flat to saddle-shaped rings-are clinically available. A deeper understanding of mitral valve function, in conjunction with several recent studies, suggest it is advisable to prefer annuloplasty rings that mimic the physiological mitral annulus shape and three-dimensional (3D) dynamic changes in order to reduce haemodynamic stress on valve components and optimize leaflet coaptation, perhaps improving valve repair durability too. This paper aims to focus on 3D annuloplasty rings, with dynamic features: MEMO 3D™ and MEMO 4D™ (Sorin Medical, New York, New York), as well as Physio Flex (Edwards Lifesciences, Irvine, California).
