Coming undone: a case of annuloplasty ring suture degeneration post mitral valve repair leading to recurrent severe MR

Echo Research and Practice, 2020
Mitral valve repair is the gold standard treatment for degenerative mitral valve disease with superior perioperative and long-term morbidity and mortality outcomes vs mitral valve replacement.

Ring-first Mitral Valve Repair [PDF]

Research Ideas and Outcomes, 2020
Mitral valve repair is one of the most frequent interventions in cardiac surgery. It involves eliminating the dysfunctional part(s) of the mitral valve and reconstructing, using the residual tissue or with the addition of prosthetic components, a ...

Impact of type and size of annuloplasty prosthesis on hemodynamic status after mitral valve repair for degenerative disease

International Journal of Cardiology: Heart & Vasculature, 2020
Objective: The aim of this study is to evaluate mitral valve hemodynamics after mitral valve repair for degenerative disease, and seek the impact of type/size of annuloplasty prosthesis on resting cardiac hemodynamics.

Mitral Valve Fenestration as a Rare Cause of Congenital Mitral Insufficiency Successfully Repaired

Brazilian Journal of Cardiovascular Surgery, 2021
A rare case of congenital mitral insufficiency characterized by a fenestration in the anterior leaflet of mitral valve is reported. At operation, the mitral valve was successfully repaired by closure of unusual valvular tissue orifice with bovine ...

Severe hemolytic anemia and acute renal failure after mitral valve repair associated with non-endothelialization of artificial chordae tendinae: case report

Journal of Cardiothoracic Surgery, 2021
Background Mechanical hemolytic anemia and acute renal failure are rare complications of mitral valve repair. Case presentation We report a unique case of severe hemolytic anemia and severe acute renal failure after mitral valve repair using artificial ...

Effect of Annuloplasty for Mitral Valve Prolapse [PDF]

Circulation: Cardiovascular Imaging, 2016
Mitral valve prolapse (MVP) is the most common cause of primary mitral regurgitation (MR), which represents leaflet or chordae elongation and is frequently accompanied by ruptured chordae. In almost all patients with this entity, annular dilatation is a common lesion.

Midterm results of mitral valve repair for atrial functional mitral regurgitation: a retrospective study

Journal of Cardiothoracic Surgery, 2020
Background Annular dilation by left atrial remodeling is considered the main cause of atrial function mitral regurgitation. Although acceptable outcomes have been obtained using mitral ring annuloplasty alone for atrial functional mitral regurgitation ...

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.

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 ...

Subannular repair for functional mitral regurgitation with reduced systolic ventricle function: rationale and design of REFORM-MR registry

Journal of Cardiothoracic Surgery, 2022
Background Functional mitral regurgitation (FMR) is one of the most common heart valve diseases that is a sequel of left ventricular remodelling. Although mitral valve annuloplasty is a standard treatment of FMR, the recurrence of FMR is a major drawback
