Transcatheter mitral valve implantation (TMVI) has been performed in high-risk and inoperable patients for degenerated mitral bioprostheses (TMVIinV) and failed annuloplasty rings (TMVIinR). TMVIinR is more challenging compared to TMVIinV because of the differences in dimensions, shapes, and contours between rings and valves. In this report, we present two clinical cases of TMVIinR that were treated by trans-septal implantation of a balloon-expandable prosthesis. In TMVI cases with an incomplete ring, the ring will be stretched out toward its anterior and commissural side, and the open side of the ring will increase in width...

Mitral annuloplasty ring thrombosis is an extremely infrequent pathology, for which no evidence-based antithrombotic management has yet been described. Herein is presented a case of heterozygous Factor V Leiden (FVL) and hyperhomocysteinemia with homozygous methylenetetrahydrofolate reductase (MTHFR) mutations that caused early thrombosis of the mitral annuloplasty ring. The clinical management and antithrombotic treatment of the patient, and the implications of hyperhomocysteinemia, are discussed. Video 1: Mobile 9-mm thrombus of mitral annuloplasty ring on two-dimensional (2D) transesophageal echocardiography...

OBJECTIVES: With the emergence of transcatheter mitral valve-in-valve/ring replacement for deteriorated bioprostheses or failed repair, comparative clinical benchmarks for surgical repeat mitral valve replacement (re-MVR) are needed. We present in-hospital and survival outcomes of a 24-year experience with re-MVR. METHODS: From January 1992 to June 2015, 520 adult patients underwent re-MVR; 273 had undergone prior mitral valve repair (pMVP) and 247 had undergone prior MVR (pMVR)...

A rare case of mitral stenosis after mitral valve repair for non-rheumatic mitral regurgitation is presented. An 81-year-old woman who had undergone mitral valve repair using an annuloplasty ring 12 years earlier, was referred to our hospital because of dyspnea during exertion. As echocardiography revealed severe mitral stenosis, and redo surgery was carried out. During the surgery, fibrous tissue covered the annuloplasty ring and extended onto both leaflets of the mitral valve, which narrowed its orifice, by rendering the leaflets stiff and immobile...

BACKGROUND: This meta-analysis compares the early and late outcomes of valve repair versus replacement, the primary surgical strategies for tricuspid valve infective endocarditis (IE). METHODS: We searched MEDLINE and EMBASE databases until 2016 for studies comparing tricuspid valve repair and replacement. RESULTS: The main outcomes were mortality, recurrent IE and need for reoperation. There were 12 unmatched retrospective observational studies with 1165 patients (median follow up 3...

We demonstrate the technical aspects of a novel adjustable mitral ring. This new ring was implanted in a female landrace pig, for training and educational purposes. It can be adjusted independently in the P1, P2 and P3 segments, if required, to treat  recurrent mitral regurgitation, and this is a key difference to comparable devices. The first-in-man implantation is anticipated in the near future.

Approximately one-third of patients suffering from aortic insufficiency (AI) present also with an ascending aortic aneurysm. AI is most commonly due to a combination of sinotubular junction and annular dilatation. Valve reimplantation or prosthetic valve replacement may not be ideal for these patients, and ascending aortic aneurysm resection with aortic valve repair using geometric internal ring annuloplasty is a simple, successful, and reproducible alternative treatment approach. In this video tutorial we demonstrate aortic valve repair using the HAART 300 annuloplasty ring with concomitant ascending aorta replacement...

Annuloplasty ring repair is a common procedure for the correction of mitral valve regurgitation. Commercially available rings vary in dimensions and material properties. Annuloplasty ring suture dehiscence from the native annulus is a catastrophic yet poorly understood phenomenon that has been reported across ring types. Recognizing that sutures typically dehisce from the structurally weaker posterior annulus, our group is conducting a multi-part study in search of ring design parameters that influence forces acting on posterior annular sutures in the beating heart...

BACKGROUND:  Transcatheter heart valve (THV) as valve-in-ring is increasingly used in the mitral position. Semi-rigid rings may serve as a more appropriate scaffold for proper anchoring of a THV as they may change from their oval to a round shape thereby fitting to the implanted THV. METHODS:  One rigid and five semi-rigid rings of four manufacturers, Edwards Physio I and II, Sorin 3D Memo, Medtronic Simulus, and St. Jude Medical (SJM) Saddle and SJM Sequin, with sizes 28 to 36 mm and Edwards Sapien III THV 23, 26, and 29 mm were used...

The tricuspid valve has historically received less attention than any other cardiac valve with regard to pathophysiology and surgical management. The tricuspid valve is part of a complex functional apparatus that includes the right atrium, right ventricle, and pulmonary circulation. Functional tricuspid regurgitation is the most common tricuspid valve disease and it occurs secondary to dilatation of tricuspid annulus and/or tethering of valve leaflets from right ventricular dilatation and dysfunction. However, recent expansion in the use of right-sided transvenous devices such as pacemakers and implantable defibrillators has been met with a parallel increase in the risk of organic tricuspid disease...

Adaptation and evolution of transcatheter aortic valve replacement (TAVR) technologies has led to approval of TAVR for consideration in patients at intermediate risk for surgical aortic valve intervention. As TAVR becomes more mainstream, attention is shifting toward percutaneous mitral valve (MV) repair and transcatheter MV replacement (TMVR) techniques. Transcatheter heart valves (both purpose-built and off-label-use TAVR valves) are being implanted during TMVR procedures to treat clinically significant MV disease (native disease, degenerated bioprosthetic valves, and dysfunctional surgical MV annuloplasty repairs) when the risk of open heart MV surgery is prohibitive...

Minimally invasive surgical mitral valve repair (MVRepair) has become routine for the treatment of mitral valve regurgitation, and indications have been expanded to include reoperations. Current European Society of Cardiology/European Association for Cardio-Thoracic Surgery guidelines for the management of valvular heart disease recommended standards in terms of mitral valve disease differentiation, timing of intervention and surgical techniques to improve patient care. Numerous minimally invasive techniques to lessen the invasiveness have been described, such as the minimal-access J-sternotomy (ministernotomy), the parasternal incision, the port-access technique and the right minithoracotomy...

BACKGROUND: Although flexible-ring annuloplasty is more inclined to increase the transmitral gradient over time, its effect on the tricuspid annulus is unknown. This study was conducted to evaluate serial changes in mean pressure gradient (mPG) across tricuspid and mitral valves after simultaneous dual implantation of flexible bands. METHODS: Seventy-one patients (median age, 61.6 years; IQR: 50.8-69.0 years) underwent simultaneous mitral/tricuspid annuloplasties using St...

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...
