Introduction: After early successful experience with transcatheter aortic valve replacement (TAVR), concept of transcatheter implantation of a new valve within a failing bioprosthetic valve emerged. Valve-in-valve (ViV) implantation seems to be a simpler option for high risk surgical patients. Methods: We performed five ViV procedures in different valve positions. We included patients with failing bioprosthetic valves with high surgical risk due to concomitant comorbidities. We performed 2 transapical ViV procedures for failing mitral bioprosthetic valves, 1 transfemoral procedure for failing pulmonary valve and 2 transfemoral ViV implantation for failing tricuspid bioprosthetic valves...

BACKGROUND: Transcatheter mitral valve replacement (TMVR) is a potential therapy for patients with symptomatic, severe mitral regurgitation (MR). The feasibility of this therapy remains to be defined. OBJECTIVE: We report our early experience with TMVR using a new valve system. METHODS: The valve is a self-expanding, nitinol valve with bovine pericardial leaflets that is placed using a transapical delivery system. Patients with symptomatic MR who were deemed high or extreme risk by the local heart teams were enrolled in a global pilot study at 14 sites (U...

Transapical off-pump echo-guided mitral valve repair with implantation of artificial ePTFE chordae with the Harpoon device has been proposed to treat patients presenting with severe mitral regurgitation due to posterior leaflet prolapse. The device is inserted in the left ventricle and steered to the surface of the diseased portion of the leaflet. The Harpoon device is actuated, and the leaflet is perforated by a needle that consequently releases an ePTFE chord that is fixed on the atrial surface by a double-helix coiled knot...

Off-pump direct coronary artery bypass grafting through a left anterior small thoracotomy is widely utilized for minimally invasive myocardial revascularization. More recently, a novel technique for transapical off-pump mitral valve repair with the NeoChord device is demonstrating its efficacy. This report describes a case of an 84-year-old male patient with coronary artery disease involving the left anterior descending coronary artery and acute severe mitral regurgitation secondary to posterior leaflet flail who underwent both off-pump coronary artery bypass and mitral valve repair with the transapical implantation of artificial chordae using the NeoChord DS 1000 system through the same anterolateral small thoracotomy...

OBJECTIVES: The transapical approach provides concurrent surgical access to the mitral and the aortic valves, the root of the aorta and the left atrium. We previously showed the feasibility of transapical cardioscopic (TAC) surgery in a non-survival porcine model. However, reproducibility and feasibility of ring implantation using TAC have not been reported. Therefore, in this study, we hypothesized that implantation of a mitral annuloplasty ring can be feasibly and safely carried out endoscopically via the apex of the heart...

In patients with mechanical aortic and mitral valve prosthesis, left ventricular (LV) endocardial ablation via retrograde transaortic or antegrade transmitral approach carry high risk of catheter entrapment and death. In such cases, ablation can be performed via ventricular transseptal or transapical approach. Transapical approach, with the ease of catheter maneuverability and better endocardial contact, may be performed surgically or percutaneously. In this case report, we describe a patient with both aortic and mitral mechanical prosthesis who underwent ventricular tachycardia (VT) ablation via percutaneous transapical endocardial approach with the use of closure device...

REVIEW
Marina Urena, Dominique Himbert, Eric Brochet, Jose Luis Carrasco, Bernard Iung, Patrick Nataf, Alec Vahanian
Transcatheter mitral valve replacement (TMVR) using balloon-expandable valves has become an alternative therapy for selected patients with mitral valve disease. Up to now, the transapical approach has been the preferred route, but the transseptal approach is becoming increasingly popular due to its reduced invasiveness and increased safety. However, transseptal TMVR procedures are technically challenging, and little is known about the screening process required before this therapy. The authors provide operators with a step-by-step approach from the screening process to follow-up care for transseptal TMVR procedures...

Transapical off-pump mitral valve repair with neochord implantation has been approved for patients presenting with severe mitral regurgitation due to leaflet prolapse or flail. The procedure is performed under real-time 2D and 3D transoesophageal echocardiography for both implantation and neochordae tension adjustment allowing real-time monitoring of haemodynamic recovery.

BACKGROUND: Hypertrophic cardiomyopathy (HCM) is a primary myocardial disease characterized by left ventricular hypertrophy in the absence of other etiologies. Clinical presentation may vary from asymptomatic to sudden cardiac death. Medical treatment is the first-line therapy for symptomatic patients. Extended left ventricular septal myectomy is the procedure of choice if medical treatment is unsuccessful or intolerable. MAYO CLINIC EXPERIENCE: More than 3,000 patients have had septal myectomy for HCM at the Mayo Clinic (MN, USA) from 1993 to 2016...

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...

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...

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...

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...
