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.

Finite element analysis of mitral valve annuloplasty in Barlow's disease [PDF]

, 2022
Barlow’s Disease affects the entire mitral valve apparatus causing mitral regurgitation. Standard annuloplasty procedures lead to an average of 55% annular area reduction of the end diastolic pre-operative annular area in Barlow’s diseased valves ...

Adjustable tricuspid annuloplasty [PDF]

Interactive CardioVascular and Thoracic Surgery, 2013
The methods for repairing functional tricuspid regurgitation (TR) are still controversial. A novel concept of tricuspid annuloplasty for functional TR was developed. A flexible annuloplasty band, through which an expanded polytetrafluoroethylene (ePTFE) thread (CV3) was passed inside the cover cloth, was secured to the tricuspid annulus.

Balancing the Benefits of Tricuspid Annuloplasty

Journal of Cardiac Surgery, 2022
Tricuspid annuloplasty for moderate to severe TR (Class I, IIb) is the current standard of practice to restore the normal tricuspid annular dimension and function (1,2). The current controversy in atrioventricular surgery concerns the indication for concomitant TA in patients with moderate TR and significant annular dilatation of at least &

Assessment of Computed Tomography Imaging for Isolated Type 1 Bicuspid Aortic Valve Repair: A Comparison between Internal and External Suture Annuloplasty Techniques

Reviews in Cardiovascular Medicine, 2023
Background: The ideal position of suture annuloplasty relative to the aortic annulus (internal or external) remains unclear. This study aimed to investigate the effectiveness of internal and external suture annuloplasty for isolated type 1 bicuspid ...

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 ...

Impact of 3D Rigid Ring Annuloplasty for Tricuspid Regurgitation: A Systematic Review and Meta-Analysis

Frontiers in Cardiovascular Medicine, 2022
BackgroundTricuspid annuloplasty (TAP) is accepted as the standard technique for correcting tricuspid regurgitation (TR). We conducted the present study to provide an overview of the contemporary results of 3D rigid ring annuloplasty for TR.MethodsA ...

Indirect Annuloplasty to Treat Functional Mitral Regurgitation: Current Results and Future Perspectives

Frontiers in Cardiovascular Medicine, 2019
The incidence of mitral regurgitation (MR) is approximately 1.7% in the developed world, and this increases to more than 10% in patients aged over 75 years.
