Papillary muscle approximation reduces systolic tethering forces and improves mitral valve closure in the repair of functional mitral regurgitationCentral MessagePerspective

JTCVS Open, 2021
Background: Undersizing mitral annuloplasty (UMA) to repair functional mitral regurgitation (FMR) lacks durability, as it forces leaflet coaptation without relieving the subleaflet tethering forces.

Mitral Annuloplasty Using A Biodegradable Annuloplasty Ring [PDF]

Operative Techniques in Thoracic and Cardiovascular Surgery, 2015
With the advent of several valve repair techniques, mitral valve repair is now preferred over mitral valve replacement as the treatment of choice for several mitral pathologic conditions. Because annular dilation is a vital component in most cases of chronic mitral regurgitation (MR), annular support is necessary to provide adequate repair and optimum ...

Pathological Remodeling of Mitral Valve Leaflets from Unphysiologic Leaflet Mechanics after Undersized Mitral Annuloplasty to Repair Ischemic Mitral Regurgitation

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2018
Background Undersized ring annuloplasty is a commonly used surgical repair for ischemic mitral regurgitation, in which annular downsizing corrects regurgitation, but alters valve geometry and elevates tissue stresses.

In Vivo Validation of Restored Chordal Biomechanics After Mitral Ring Annuloplasty in a Rare Ovine Case of Natural Chronic Functional Mitral Regurgitation

Journal of Cardiovascular Development and Disease, 2020
Mitral valve chordae tendineae forces are elevated in the setting of mitral regurgitation (MR). Ring annuloplasty is an essential component of surgical repair for MR, but whether chordal forces are reduced after mitral annuloplasty has never been ...

What Is the Optimal Mitral Valve Repair for Isolated Posterior Leaflet Prolapse to Achieve Long‐Term Durability?

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2023
Background This study assessed risk factors for mitral regurgitation (MR) recurrence or functional mitral stenosis during long‐term follow‐up in patients undergoing mitral valve repair for isolated posterior mitral leaflet prolapse.
