We describe a simple technique for the accurate adjustment of polytetrafluoroethylene neochordae length in degenerative mitral regurgitation using the annuloplasty ring's own suture as a reference instead of using sophisticated or less precise maneuvers. Two threads of the annuloplasty ring suture are placed at the level of the mitral valve annulus plane to be used as a reference to tie the neochordae.

Objectives: Artificial neochordae implantation is commonly used for mitral valve (MV) repair. However, neochordae length estimation can be difficult to perform. The objective was to assess the impact of neochordae length changes on MV haemodynamics and neochordal forces.

Objective: Estimating neochord lengths during mitral valve repair is challenging, because approximation must be performed largely based on intuition and surgical experience. Little data exist on quantifying the effects of neochord length misestimation. We aimed to evaluate the impact of neochord length on papillary muscle forces and mitral valve hemodynamics, which is especially pertinent because increased forces have been linked to aberrant mitral valve biomechanics.

Growing interest in minimalizing surgical trauma during heart procedures stimulated the development of robotic mitral valve surgery in the late 1990s. Initially, the new technology was slowly adopted in clinical practice. However, following encouraging results by teams that adopted robotic heart surgery early on, a growing interest in implementation of robotic mitral valve surgery has emerged.

Background: Mitral valve repair using expanded polytetrafluoroethylene sutures to replace mitral chordae tendineae is a well-established procedure. However, the incidence of neo-chordae failure causing recurrent mitral regurgitation is not well defined.
Methods: We have reviewed the reported cases of complications after mitral valve repair related to the use of neo-chordae.
