OBJECTIVES: This study is the first report of 2 cases of HighLife (HighLife, Paris, France) implantation in humans. BACKGROUND: Transcatheter mitral valve implantation represents a promising approach to treating mitral regurgitation in patients at increased risk of perioperative mortality. The HighLife transcatheter mitral valve is a 2-component system. The valve is implanted in the mitral position and is anchored by interacting and then reaching an equilibrium position with a previously positioned subannular implant...

Objective: To present the results of a new experimental device developed to facilitate the transapical access in endovascular treatment of structural heart diseases. It aims to reduce the risk of bleeding and complications in this type of access and demonstrate the device as a safe, fast and effective alternative. Methods: CorPoint is composed of three parts: introducer, base with coiled spring, and closing capsule. By rotating movements, the spring is introduced into the myocardium and progressively approaches the base to the surface of the heart...

BACKGROUND: Transcatheter mitral valve implantation (TMVI) is still in its infancy and is mainly limited to valve-in-valve or valve-in-ring implantations. We present the early experience with TMVI for severe calcified native MV stenosis. METHODS: Between January 2014 and June 2015, 6 of 11 patients screened (mean age, 77.4 ± 6.3 years; 66% men) with severe native mitral valve (MV) stenosis (mean gradient [Pmean], 11.1 ± 2.1 mm Hg; mean effective orifice area [EOA], 0...

Selecting the ventricular access site on the basis of mitral valve anatomy improves the outcomes for a subgroup of patients undergoing the transapical echocardiographically guided NeoChord (NeoChord, Inc, St. Louis Park, MN) repair procedure to correct mitral regurgitation and who have a leaflet-to-annulus index lower than the recommended efficacy threshold of 1.25.

We present a case of a patient with severe mitral regurgitation referred to our Institution for an echocardiographic examination as part of the routine workup to assess the eligibility for mitral valve percutaneous repair with either the MitraClip or Cardioband systems. Echocardiography showed the presence of an unusual interatrial membrane in the left atrium that represented a contraindication for the puncture of the interatrial septum. The patient was finally deferred to percutaneous mitral valve replacement using transapical access...

BACKGROUND: Simultaneous transapical implantation of transcatheter heart valves in the native mitral and aortic position may be considered as an alternative to surgical valve replacement in high-risk patients presenting with combined valve disease. CASE PRESENTATION: A 59-year-old female with severe aortic stenosis, severe mitral stenosis with mild mitral insufficiency, persistent atrial fibrillation, severe chronic obstructive pulmonary disease and NYHA class of IV was evaluated by our interdisciplinary heart team...

Despite advances in surgical techniques for mitral valve repair, more than 20% of patients require reoperation within 10 years due to recurrence of severe mitral regurgitation. However, reoperations on the mitral valve are often associated with increased morbidity and mortality. We report a transapical mitral valve-in-ring implantation in a patient who had undergone mitral valve repair for ischemic mitral regurgitation using a complete semi-rigid Memo 3D mitral ring (LivaNova Group, Milan, Italy).

OBJECTIVE: Mitral valve (MV) regurgitation due to degenerative MV disease is the leading cause of cardiac death in dogs. We carried out preliminary experiments to determine the feasibility and short-term effects of beating-heart MV repair using an expanded polytetrafluorethylene (ePTFE) chordal implantation device (Harpoon TSD-5) in dogs. ANIMALS: This study involved six healthy purpose-bred Beagles (weight range 8.9-11.4 kg). MATERIAL AND METHODS: Following a mini-thoracotomy performed under general anesthesia, the TSD-5 was used to place 1 or 2 artificial ePTFE cords on the anterior MV leaflet or the posterior MV leaflet via a left-ventricular transapical approach...

Transcatheter mitral valve replacement has been successfully performed with the use of aortic transcatheter heart valves in hundreds of patients worldwide with severe dysfunction of a degenerated mitral bioprosthesis and high surgical risk for repeat operation. The delivery approach in the vast majority of the mitral valve-in-valve procedures has been transapical. Although the transseptal approach may be more technically challenging, it is less invasive and may be preferred by patients. Data from case series and a large international registry suggest that patients treated with transseptal mitral valve-in-valve have faster recovery, more improvement in left ventricular ejection fraction and possibly lower mortality compared with patients treated with transapical approach...

BACKGROUND: Various approaches such as antegrade trans-septal, retrograde transfemoral and transapical techniques have been used to close mitral paravalvular leak (PVL) in patients with an aortic prosthesis. During the implementation of these techniques, an arteriovenous guidewire loop is often created for device delivery. However, passing through a mechanical aortic valve may cause hemodynamic compromise and prolong the procedure. To date, no studies have evaluated antegrade mitral PVL closure without the use of an arteriovenous wire loop in patients with a mechanical aortic prosthesis...

Repeat cardiac surgery in patients with a previous sternotomy is associated with significant morbidity and mortality. While transcatheter aortic valve implantation in high risk surgical patients is now well established, experience with transcatheter mitral valve replacement is still at an early stage. Although many successful reports of transcatheter mitral valve replacements now exist, the predominant approach has been via a transapical approach. It is likely that, as with the evolution of favoured access routes for transcatheter aortic therapies, future directions for transcatheter mitral valves will focus on smaller delivery systems favouring the transvenous transseptal approach where possible...

We report about the first-in-man implantation of the Mitra-SpacerTM (Cardiosolutions Inc., West Bridgewater, MA/USA). It was implanted transapically. FMR was reduced to moderate degree. At two-months, while in NYHA II, LVEF had improved, but FMR increased and 2mL was added, reducing FMR to mild degree. Despite anticoagulation, thrombi developed around the device and the valve was replaced at eight-months. The Mitra-SpacerTM successfully bridged this patient to surgery after LVEF had recovered.

OBJECTIVES: A transcatheter heart valve technique can be used in failed mitral valve repairs with annuloplasty rings, deterioriated bioprostheses and in mitral annular calcification, all serving as 'docking stations' for balloon-expandable valves. Specially designed transcatheter mitral valve platforms are used in ongoing studies for native mitral valve regurgitation. We present our single centre experience with transcatheter mitral valve implantation-transapical approach procedures in eleven patients...

INTRODUCTION: To facilitate coaxial device deployment in transcatheter mitral valve replacement (TMVR), a coaxial approach to the mitral annular plane is needed. We sought to establish a method to determine an 'orthogonal' left ventricular (LV) access point for transapical TMVR and to quantitatively characterize its location in patients with severe mitral regurgitation using cardiac computed tomography. METHODS: Cardiac CT data sets of 54 patients with moderate-severe mitral regurgitation evaluated for potential TMVR were analyzed...

OBJECTIVES: The aim of this study was to compare early outcomes and survival of patients undergoing minimally invasive mitral valve replacement through a right anterior minithoracotomy (MIMVR) versus patients undergoing transcatheter transapical mitral valve-in-valve (M-VIV) implantation for a failed mitral bioprostheses. METHODS: From 2005 to 2015, 61 patients with a failed mitral bioprosthesis underwent either MIMVR ( n  = 40 patients, 65.6%) or M-VIV implantation ( n  = 21, 34...

AIMS: We report our experience with the CardiAQ prosthetic valve using both transapical and transseptal access. Aim of our study was proving the feasibility, safety and effectiveness of a novel transcatheter mitral valve bioprosthesis. METHODS: Four patients with severe mitral regurgitation, not eligible for mitral valve surgery, were treated with the CardiAQ valve. The procedures were performed under general anaesthesia, fluoroscopic and transesophageal echocardiographic guidance...
