Transcatheter mitral valve implantation

Heike Baumgarten, John J Squiers, William T Brinkman, J Michael DiMaio, Ambarish Gopal, Michael J Mack, Robert L Smith
Mitral annular calcification (MAC) is a chronic degenerative process at the fibrous base of the mitral valve. It is a feared diagnosis in the context of mitral valve operations because of the risk of severe adverse events such as atrioventricular disruption, injury to the circumflex artery during debridement, and difficult placement of annular sutures. We report a series of 3 consecutive female patients with severe circular MAC who underwent successful mitral valve replacement through a lateral minithoracotomy with use of an inverted transcatheter aortic valve...

AIMS: The use of the MitraClip system has gained widespread acceptance for the treatment of patients with mitral regurgitation (MR) who are not suitable for the conventional surgery. This study sought to investigate the early and 1-year outcome after MitraClip therapy of patients with MR and cardiac comorbidities. METHODS AND RESULTS: Outcomes through 12-month follow-up of patients (n = 528) who underwent MitraClip implantation were obtained from the German transcatheter mitral valve interventions (TRAMI) registry...

We describe a successful transcatheter, transapical mitral valve implant within a failed mitral bioprosthesis (valve-in-valve) in a symptomatic 86-year-old patient with prohibitive surgical risks, using the new Sapien 3 balloon-expandable valve. Post-deployment echocardiographic profile of the valve-in-valve was satisfactory and the patient was discharged from hospital uneventfully. This is the first reported case of the Sapien 3 valve used in the mitral valve-in-valve setting.

Surgical techniques for the treatment of mitral valve disease (MVD) have continuously evolved; however, anatomical details like severe annular calcification remain challenging and require sophisticated surgical strategies. Among patients with symptomatic MVD referred for surgical valve repair or replacement, four presented with circumferential calcification of the mitral annulus precluding conventional surgical techniques. Successful treatment by implanting a balloon-expandable transcatheter aortic heart valve using an antegrade surgical access was performed...

For the treatment of structural heart disease, current options in the catheterization laboratory include MitraClip® implantation for treating severe mitral regurgitation, transcatheter aortic valve implantation (TAVI), closure of a patent foramen ovale (PFO) and occlusion of the left atrial appendage (LAA). These treatment options are based on a precise diagnosis provided by modern cardiac imaging, which is indispensable for treatment recommendations. Its importance for supporting the invasive procedures in the catheterization laboratory is less well known...

As transcatheter mitral replacement technologies have recently been applied in early clinical trials, the question as to whether valve implantation would have the potential to become the leading percutaneous mitral valve therapy has been raised. The aim of this report is to give an overview of the different peculiarities of percutaneous replacement and repair techniques, and to predict whether the two approaches will have a complementary rather than a competitive clinical role in the near future.

There is a growing practice of transcatheter treatment of failed mitral valves after cardiac surgery, including valve-in-valve and valve-in-ring. Although commonly successful, these procedures can be associated with device malposition (including delayed malposition) and elevated post-procedural gradients (especially when performed inside small surgical valves). Valve-in-ring procedures have elevated risks of left ventricular outflow tract obstruction and post-procedural regurgitation. Careful patient selection and meticulous evaluation of patient anatomy and surgical implant characteristics are essential to achieve optimal clinical results with mitral valve-in-valve and valve-in-ring implantation...

AIMS: The aim of this study was to introduce and demonstrate the feasibility in an acute preclinical model of a new transcatheter heart valve concept with a self-expanding wire frame, polymeric leaflets and a sealing component. METHODS AND RESULTS: The TRISKELE valve was developed based on a previously validated polymeric leaflet design, an adaptive sealing cuff and a novel nitinol wire frame which reduces stress on the leaflets and radial pressure on the surrounding tissue...

OBJECTIVES: The authors propose a novel transcatheter transection of the anterior mitral leaflet to prevent iatrogenic left ventricular outflow tract (LVOT) obstruction during transcatheter mitral valve replacement (TMVR). BACKGROUND: LVOT obstruction is a life-threatening complication of TMVR caused by septal displacement of the anterior mitral leaflet. METHODS: In vivo procedures in swine were guided by biplane x-ray fluoroscopy and intracardiac echocardiography...

BACKGROUND: Although associated with left heart pathologies, functional tricuspid regurgitation (FTR) is often left untreated during left heart surgery. Hence, owing to its degenerative character, reoperation is often needed, encompassing an impressive (25% to 35%) mortality rate. Thus transcatheter approaches to FTR are raising great interest. OBJECTIVES: The authors evaluated the post-treatment effectiveness of the edge-to-edge technique using the percutaneous mitral valve repair device in an ex vivo pulsatile model of FTR...

BACKGROUND: Whilst the majority of the patients with severe aortic stenosis can be directly addressed to surgical aortic valve replacement (AVR) or transcatheter aortic valve implantation (TAVI), in some instances additional information may be needed to complete the diagnostic workout. We evaluated the role of balloon aortic valvuloplasty (BAV) as a bridge-to-decision (BTD) in selected high-risk patients. METHODS: Between 2007 and 2012, the heart team in our Institution required BTD BAV in 202 patients...

An 82-year-old woman with severe aortic stenosis was referred. She had previously undergone mitral valve replacement. We planned transcatheter aortic valve implantation (TAVI) with transfemoral approach. We planned to use the Safari-dedicated TAVI guidewire. No studies have reported clinical application of the dedicated TAVI guidewire in a patient with the previous mitral valve replacement. Thus, we conducted a simulation using a three-dimensional heart model to confirm the safety of the procedure. The procedure was successful without any complications...

Mitral annular calcium (MAC) is a common finding in older patients referred for transcatheter aortic valve implantation (TAVI). Multidetector computed tomography (MDCT) allows fine quantification of the calcific deposits. Our objective was to estimate the prevalence of MAC and associated mitral stenosis (MS) in patients referred for TAVI using MDCT. A cohort of 346 consecutive patients referred for TAVI evaluation was screened by MDCT for MAC: 174 had MAC (50%). Of these patients, 165 patients (95%) had mitral valve area (MVA) assessable by MDCT planimetry (age 83...

OBJECTIVE: A small number of transcatheter mitral valve implants (TMVIs) have been reported using devices designed to treat secondary mitral regurgitation (MR). However, MR has many etiologies, and patients have a broad spectrum of annular size, geometry, and lesions. There are a number of technical challenges for TMVI including left ventricular outflow tract obstruction and paravalvular MR. Thirty days' outcome of first-in-man implants with a novel TMVI device is reported. METHODS: The Tendyne TMVI system consists of a porcine pericardial valve in a tethered nitinol frame...

A 73-year-old woman underwent open mitral valve replacement with the transcatheter Edwards SAPIEN XT valve (Edwards Lifesciences, Corp, Irvine, CA USA) on cardiopulmonary bypass in a native, stenotic mitral valve. Because of left ventricular outflow tract obstruction, the patient died 25 days after implantation. There are previous reports of transcatheter valve implantation in native mitral valve with procedural success. However, in one case report, the patient died 10 days postoperatively.
