Maurizio Taramasso, Azeem Latib
Percutaneous mitral valve therapies are emerging as an alternative option for high-risk patients who are not good candidates for conventional open-heart surgery. Recently, multiple technologies and diversified approaches have been developed and are under clinical study or in preclinical development. This article on transcatheter mitral annuloplasty devices, describes the different technologies, and reports on the initial clinical and preclinical experiences.

OBJECTIVES: The purpose of our study is to verify, whether percutaneous mitral annuloplasty results in reverse remodeling in patients with functional mitral regurgitation (FMR) and impaired ejection fraction (EF) and to investigate which echo parameters may help in prediction of the efficacy of the procedure. BACKGROUND: FMR exacerbates left ventricular (LV) dilatation and contributes to both LV remodeling and heart failure. METHODS: We analyzed baseline and 1 month follow-up data in 22 consecutive patients with FMR, who underwent successful percutaneous trans-coronary venous mitral annuloplasty with the Carillon device...

We report a case of catastrophic hemodynamic compromise secondary to pannus ingrowth and severe mitral stenosis occurring years after repair of a nonrheumatic mitral valve. The initial repair included closure of a posterior leaflet cleft and implantation of an annuloplasty ring. We describe a hybrid treatment strategy for this severely compromised patient, which included initial placement of a right ventricular assist device followed by percutaneous balloon mitral valvuloplasty and, eventually, a definitive mitral valve reoperation...

Functional mitral regurgitation (FMR) is common in severe heart failure. Medical therapy is the standard of care since the role of surgery is less established. Various trans-catheter percutaneous techniques may avoid the risks of surgery; such as edge-to-edge repair using MitraClip system (Abbott Vascular, Illinois, USA) and CARILLON® Mitral Contour System® (Model XE2; Cardiac Dimensions., Kirkland, WA, USA). We present the case of a 41-year-old man with severe dilated cardiomyopathy, NYHA IIIb, and grade 3 MR...

OBJECTIVE: Functional (or secondary) mitral regurgitation (FMR) is associated with greater morbidity and worse outcomes in patients with congestive heart failure (CHF) and cardiomyopathy. The Carillon® Mitral Contour System® is a coronary sinus-based percutaneous therapy to reduce FMR. We evaluated the safety and efficacy of a modified version of the Carillon device in the treatment of patients with cardiomyopathy and FMR. METHODS: 36 patients with CHF, depressed left ventricular function (ejection fraction <40%) and at least moderate FMR underwent the Carillon device implant...

BACKGROUND: The spatial relationship of the coronary sinus-great cardiac vein (CS-GCV) to free posterior portion of the mitral valve annulus (MVA) and left circumflex coronary artery (LCx) has gained importance with the advent of cardiovascular interventional procedures such as percutaneous transvenous mitral annuloplasty (PTMA) and mitral isthmus (MI) ablation. METHODS: In 50 normal (nondilated cardiomyopathy, or non-DCM) and 20 dilated cardiomyopathy (DCM) cadaveric hearts, the diameter and distance from the MVA of CS-GCV and its spatial relationship to LCx along the free posterior portion of the MVA were studied...

Percutaneous approaches to reduce mitral regurgitation in ischemic cardiomyopathy have stirred interest recently. Patients with ischemic cardiomyopathy and functional mitral regurgitation often meet criteria for cardiac resynchronisation therapy to improve left ventricular function as well as mitral regurgitation, and alleviate symptoms. This case shows that implantation of a pacing lead in the coronary sinus to restore synchronous left and right ventricular contraction is feasible, despite the presence of a remodeling device in the coronary sinus...

OBJECTIVES: This study sought to examine the feasibility, safety, and intermediate-term outcomes in patients undergoing percutaneous transvenous transcatheter mitral valve implantation in failed bioprosthesis, ring annuloplasty, and calcific mitral stenosis. BACKGROUND: Surgical mitral valve replacement in patients with previous surgery or severe mitral annular calcification (MAC) is often associated with high or prohibitive risk. METHODS: Percutaneous transfemoral antegrade transseptal implantation of Edwards SAPIEN prosthesis (Edwards Lifesciences, Irvine, California) was performed in 48 patients with degenerated mitral bioprosthesis (n = 33), previous ring annuloplasty (n = 9), and severe MAC (n = 6)...

Percutaneous transvenous mitral annuloplasty (PTMA) has evolved as a latest procedure for the treatment of functional mitral regurgitation. It reduces mitral valve annulus (MVA) size and increases valve leaflet coaptation via compression of coronary sinus (CS). Anatomical considerations for this procedure were elucidated in the present study. In 40 formalin fixed adult cadaveric human hearts, relation of the venous channel formed by CS and great cardiac vein (GCV) to MVA and the adjacent arteries was described, at 6 points by making longitudinal sections perpendicular to the plane of MVA, numbered 1-6 starting from CS ostium...

OBJECTIVES: Recurrent mitral regurgitation (MR) is common after surgical and percutaneous (MitraClip) treatment of functional MR (FMR). However, the Everest II trial suggested that, in patients with secondary MR and initially successful MitraClip therapy, the results were sustained at 4 years and were comparable with surgery in terms of late efficacy. The aim of this study was to assess whether both those findings were confirmed by our own experience. METHODS: We reviewed 143 patients who had an initial optimal result (residual MR ≤ 1+ at discharge) after MitraClip therapy (85 patients) or surgical edge-to-edge (EE) repair (58 patients) for severe secondary MR (mean ejection fraction 28 ± 8...

Prosthetic annuloplasty rings are a common treatment modality for mitral regurgitation, and recently, percutaneous implantation techniques have gained popularity due to their favorable safety profile. Although in common use, biocompatibility of annuloplasty rings has been reported only sparsely in the literature, and none of these reports used the percutaneous technique of implantation. We report on the biocompatibility and the systemic safety of a novel transcatheter mitral valve annuloplasty ring (AMEND™) in 6 minipigs...

A 55-year-old man had undergone mitral annuloplasty for mitral regurgitation with posterior mitral prolapse 3 years prior. He was examined at our hospital for dyspnea and fatigue. A coronary angiogram revealed iatrogenic chronic total occlusion (CTO) in the left circumflex coronary artery. We performed percutaneous coronary intervention (PCI) and successfully placed an everolimus-eluting stent. An intravascular ultrasound (IVUS) showed an impaired coronary artery at the occlusion site. To our knowledge, this is the first reported successful PCI for iatrogenic CTO after mitral valve repair...

Severe mitral regurgitation (MR) is a growing medical challenge in today's aging population, leading to increased health expenditure due to the resultant morbidity and mortality. Surgery, either replacement or repair, has been the mainstay of therapy for primary MR. In high-risk or inoperable patients, treatment was limited to medical therapy until 2008. Since then, alternative percutaneous therapies have been introduced and have proven to be safe and effective in patients with secondary MR. Edge-to-edge repair with the MitraClip system is applied worldwide for primary and secondary MR...

In recent years, various percutaneous techniques have been introduced for the treatment of mitral regurgitation (MR), including direct leaflet repair, annuloplasty and left ventricular remodeling. Percutaneous mitral repair targets both primary degenerative and secondary mitral valve regurgitation and may be considered in selected high-surgical-risk patients. The assessment of mitral functional anatomy by echocardiography and computed tomography is crucial when selecting the appropriate repair strategy, according to the regurgitant valve lesion and the surrounding anatomy...
