Objective Owing to the complex anatomy of the mitral valve, successful surgical repair of degenerative regurgitation remains a challenging procedure in cardiac surgery. Methods This paper aimed to report on our single-center experience with 20 patients who received an adjustable annuloplasty ring (Cardinal ring, ValtechCardio Ltd, Or Yehuda, Israel) as part of their mitral valve repair procedure. The device allows for intraoperative echocardiography-guided ring size adjustments under beating-heart conditions. Results All of the 20 patients left the operating room without any residual mitral regurgitation. There was no risk of systolic anterior movement (SAM) because of image-guided fine tuning of the ring before weaning the patient from bypass. Conclusions Further multicenter data are required to prove the concept of adjustable annuloplasty devices.

Leaflet Prolapse

The edge-to-edge repair (ETER) technique is a mitral valve (MV) repair procedure. It approximates the leading edges of the mitral leaflets by use of sutures, exhibits promising predictable repair results and offers the advantage of being performed pericutaneously without the need for open heart surgery. The technique is becoming a popular surgical procedure to correct MV prolapse caused by abnormal chordal elongation. MV prolapse leads to mitral regurgitation (MR). Generally the ETER technique is performed as a secondary procedure to ring annuloplasty. Although some groups have performed ETER without the ring annuloplasty, recent studies have shown that ETER technique alone leads to substandard results [1]. It is necessary to define the MV annulus mechanics in ETER condition during valve closure or mid-systole as it directly affects the annulus tension (AT) in the annulus plane. AT in the annulus plane is an important force component which balances the myocardium force and contributes to maintaining the annulus shape and size. This AT change caused by the ETER can lead to annulus dilation, reoccurrence of MR and impact reintervention. The objective of the current study is to understand this AT change in the MV annulus tension during the mid-systole in the ETER condition in order to improve the long term efficacy of the ETER procedure on MV annulus tension, after the technique has been applied with both anterior leaflet prolapse and posterior leaflet prolapse.

Additional Value

Percutaneous mitral valve repair is a sophisticated procedure which requires a unique collaboration between the interventionalist and echocardiographer since it is mainly driven by real-time transoesophageal echocardiography (TEE). Fluoroscopy plays a lesser role. We will review the role of echocardiography during the different procedural steps and the additional value of three-dimensional (3D TEE).

Background: Mitral valve regurgitation (MR) is the most common valvular heart disease and current variables associated with MR recurrence are still controversial. We aim to develop a machine learning-based prognostic model to predict causes of mitral valve (MV) repair failure and MR recurrence. Methods: 1000 patients who underwent MV repair at our institution between 2008 and 2018 were enrolled. Patients were followed longitudinally for up to three years. Clinical and echocardiographic data were included in the analysis. Endpoints were MV repair surgical failure with consequent MV replacement or moderate/severe MR (>2+) recurrence at one-month and moderate/severe MR recurrence after three years. Results: 817 patients (DS1) had an echocardiographic examination at one-month while 295 (DS2) also had one at three years. Data were randomly divided into training (DS1: n = 654; DS2: n = 206) and validation (DS1: n = 164; DS2 n = 89) cohorts. For intra-operative or early MV repair failure assessment, the best area under the curve (AUC) was 0.75 and the complexity of mitral valve prolapse was the main predictor. In predicting moderate/severe recurrent MR at three years, the best AUC was 0.92 and residual MR at six months was the most important predictor. Conclusions: Machine learning algorithms may improve prognosis after MV repair procedure, thus improving indications for correct candidate selection for MV surgical repair.

Objective The purpose of this study was to demonstrate the feasibility of simple to complex endoscopic robotic mitral valve repair, using a lateral approach. Methods Data were retrospectively collected on 201 patients undergoing a lateral “ports only” endoscopic robotic mitral valve repair at three institutions. Techniques of aortic occlusion included the endoaortic balloon or a transthoracic clamp. The efficacy of the repair was measured intraoperatively by transesophageal echocardiogram. Results Two hundred one patients with a mean age of 55.2 ± 14.2 were intended to undergo elective robotic mitral valve surgery. One hundred eighty-six (92.5%) were scheduled for a repair procedure and 15 (7.5%) were scheduled for replacement. The repair was accomplished in 179 of 186 (96.2%) of patients. Eight patients (4.3%) required a conversion to sternotomy incision. Seven converted patients received a mitral valve repair and one received a replacement mitral valve. Mitral valve pathology included 10% isolated anterior leaflet involvement, 43% isolated posterior leaflet involvement, and 6% bileaflet pathology, and the remaining patients had dilated annulus, chordal rupture, or elongation. One hundred seventy-nine patients (96.2%) had regurgitation grade of 0 to 1 after repair. Two patients (1%) died. Other adverse events included reoperation for valve-related complications, 2 of 201 (1%); reoperation for cardiac-related complications, 3 of 201 (1.5%); and new onset of atrial fibrillation, 35 of 201 (17.4%). Conclusions A lateral endoscopic robotic approach to mitral valve repair is safe, feasible, and can be performed consistently with acceptable postoperative results. Further follow-up is required to determine the long-term efficacy of this approach to robotic mitral valve repair.

The authors present a case report of a mitral valve repair procedure featuring beating-heart, sternal-sparing implantation of neo-chordae. The 73-year-old female patient had severe mitral regurgitation (MR) pre-operatively, but no MR post-operatively and at 30-day follow-up. The patient was enrolled in the Transapical artificial chordae tendineae (TACT) trial sponsored by NeoChord Inc.
