Annuloplasty ring

Eva Karolina Harmel, Hermann Reichenspurner, Evaldas Girdauskas
OBJECTIVE: Mitral valve repair using an undersized complete annuloplasty ring in secondary mitral regurgitation with restricted leaflet motion during systole (Carpentier's surgical classification of mitral valve pathology: type IIIb) only inadequately addresses the underlying left ventricular disease. This may lead to an ongoing ventricular remodelling and progressive papillary muscle displacement with increasing leaflet tethering. Several subannular techniques have been proposed to counteract the reoccurrence of mitral regurgitation after mitral valve repair...

OBJECTIVES: This study was performed to analyse the impacts of functional mitral stenosis (MS) following mitral valve (MV) repair on late cardiac function and new onset of atrial fibrillation or survival. METHODS: We retrospectively reviewed 602 patients with mitral regurgitation who underwent MV repair for Type II dysfunction from 2001. Functional MS was diagnosed when the mean transmitral pressure gradient (MTPG) was ≥5 mmHg on postoperative echocardiography...

OBJECTIVE: to examine relationship between anatomical changes of the left ventricle (LV), dynamics of velocity of its volume modification, and blood flows in the LV in patients with mitral regurgitation (MR) before and after surgical treatment. MATERIALS AND METHODS: We included into this study 58 patients with severe 3-4 degree MR (38 men, 20 women aged 24-69 [mean age 51±9] years) in sinus rhythm (96 %) or atrial fibrillation (4 %). The control group included 86 healthy volunteers, mean age 39±7 years...

Approximately half of all tricuspid valves consist of four or more leaflets; however, no previous reports have discussed how to implant an annuloplasty ring in these multi-leaflet valves. We herein define the shoulder point of the tricuspid annulus and the annuloplasty ring and advocate a simple and universal fitting method to avoid deforming the tricuspid valve after ring implantation.

OBJECTIVES: Remodelling with extra-aortic ring annuloplasty has emerged as an alternative approach to root reimplantation. However, no studies have yet compared outcomes between procedures. The aim of this study was to compare mid-term outcomes in patients undergoing reimplantation versus remodelling with extra-aortic annuloplasty. METHODS: From 2001 to 2017, 142 patients underwent root remodelling with extra-aortic annuloplasty (n = 83, 48 ± 13 years) or a reimplantation technique (n = 59, 48 ± 12 years) at the Montreal Heart Institute...

BACKGROUND: Artificial chord implantation has become one of the most applied techniques for mitral valve repair (MVR). Many techniques have been described with the goal of optimizing neochord implantation. A new annuloplasty device designed to simplify the determination of appropriate neochord length has been recently introduced. We will describe our initial experience with this new device. METHODS: The semirigid device is equipped with removable loops on the posterior aspect of the ring...

BACKGROUND: Although numerous reports have described suturing techniques for tricuspid annuloplasty, most studies were not based on a detailed anatomy of the tricuspid annulus. Thus, the definition of the tricuspid commissures remains unclear. This study aimed to clearly define the commissures and leaflets of the tricuspid valve and subvalvular structures, and to define a standard method for tricuspid annuloplasty. METHODS: In 27 normal heart specimens without cardiac disease, the tricuspid commissure was defined using indentations of the leaflets as a point, not an area, and the length of each tricuspid annulus was measured...

BACKGROUND: We assessed the mitral annular motion after mitral valve repair with the Sorin Memo 3D® (Sorin Group Italia S.r.L., Saluggia, Italy), which is a unique complete semirigid annuloplasty ring intended to restore the systolic profile of the mitral annulus while adapting to the physiologic dynamism of the annulus, using transesophageal real-time three-dimensional echocardiography. METHODS: 17 patients (12 male; mean age 60.4 ± 14.9 years) who underwent mitral annuloplasty using the Memo 3D ring were investigated...

Mitral valve prosthetic ring annuloplasty represents a key milestone in the history of mitral valve repair, delivering restoration of annular shape and size. Increased leaflet coaptation, together with significant reduction in stress on sutures, has ensured predictability and immediate stability for valve repair, both of which were lacking with previous techniques. Long-term durability of repair seems to be positively affected by placement of an annuloplasty ring, and by following the well-established, standardized approach described in our tutorial, this procedure can be performed with a very low surgical risk...

Tricuspid valve regurgitation (TR) is frequently encountered and is most often functional (FTR) in nature. Surgical tricuspid valve (TV) treatment is well established in specialized centers. While transcatheter therapy for other valve disease is well established, interventional treatment of TV disease is still in its early stages. With the increasing adoption of catheter-based treatments, there is a growing interest in and need for interventional treatments for TR. An extensive literature search was methodologically performed aiming for an integrative review paper...

BACKGROUND: To investigate the association between the coaptation height of mitral valve and mitral regurgitation after mitral valve repair. METHODS: From Sep 2014 to Jun 2015, 20 patients underwent mitral valve valvuloplasty for mitral regurgitation were included. Ring annuloplasty was performed in all cases. Mitral valve short-axis dimension (MVd), coaptation height (CH), Left ventricular ejection fraction (LVEF) were measured by the transesophageal echocardiography before the operation in operation room and 3 months and 12 months after the operation by the transthoracic echocardiography...

BACKGROUND: There are few reports regarding factors related to late-onset of atrial fibrillation (Af) after mitral valve repair, which can compromise long-term outcome. We analyzed the risk factors for late Af after mitral valve repair. METHODS AND RESULTS: Between 2001 and 2015, 318 patients (214 males; median, 57.7 years) underwent mitral valve repair for degenerative mitral insufficiency (MI) without concomitant aortic valve disease in our institute. Patients with a history of paroxysmal or chronic Af preoperatively were excluded...

We describe a simple technique for the accurate adjustment of polytetrafluoroethylene neo-chordae length in degenerative mitral regurgitation using the annuloplasty ring own suture as reference, instead of using sophisticated or less precise maneuvers. Two threats 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 neo-chordae.

OBJECTIVES: The failure of mitral repairs can be the result of inadequate leaflet coaptation length (CL< 8 mm at the A2-P2 level). A new annuloplasty ring conceived by the authors enables post-surgical CL increase using percutaneous balloon catheter technology. We conducted preclinical studies to assess the in vivo feasibility of the procedure and the safety of the postimplant deformable mitral ring. METHODS: The new annuloplasty ring allows the percutaneous and progressive displacement of each of the 3 anatomical regions of the posterior mitral annulus towards the anterior...

We present the case of a high-risk patient with symptomatic severe mitral regurgitation following a surgical annuloplasty ring. An inverted aortic Edwards Sapien 3 bioprosthesis (Edwards Lifesciences, Irvine, CA) was successfully implanted through a transapical approach inside the previously implanted annuloplasty ring.
