“… 10 , 15 The main limitation of this procedure is it being restricted to patients without severe dilatation of mitral annulus, relatively normal leaflets, mitral valve prolapse and central regurgitation. 6 Moreover, clinical results indicate the inability of the technique to eliminate regurgitation in all patients. 21 In fact, the edge-to-edge technique was developed as an adjunct to standard surgical repair procedures, and its use as a stand-alone technique is still debated.…”

“…Despite the pertinent clinical need, 6 , 7 the translation of transcatheter valve technologies to the mitral position has been hindered by the need of alternative engineering strategies, taking into account the complex morphology of the valve, the higher transvalvular pressure and the larger size of the required devices. 48 Also, this application necessitates the adaptation of the delivery and deployment methods, sizing algorithms, intraprocedural imaging, failure modes and post procedural assessment parameters, all of which are unique to the mitral position.…”

Mitral regurgitation is one of the most common forms of heart valve disorder, which may result in heart failure. Due to the rapid ageing of the population, surgical repair and replacement treatments, which have represented an effective treatment in the past, are now unsuitable for about half of symptomatic patients, who are judged high-risk. Encouraged by the positive experience with transcatheter aortic valves and percutaneous reconstructive mitral treatments, a number of research groups are currently engaged in the development of minimally invasive approaches for the functional replacement of the mitral valve. The first experiences have clearly demonstrated that the approach is feasible and promising, though significant progress is still required in the prostheses design and implantation procedures before the treatment can establish as a safe and effective solution. This review analyses the devices currently at a most advanced stage of development, describing their main features and the technical solutions that they adopt in order to respond to the functional requirements of the most challenging of the heart valves.

“…26 However, most surgical repair procedures are not complex, consisting of simple annuloplasty alone. 17 Percutaneous coronary sinus approaches to mitral annuloplasty have been reported to reduce MR in animal models of global left ventricular dysfunction, 19 acute ischemia, 21 and chronic infarction.…”

Background-Mitral annuloplasty is the most common surgical procedure performed for ischemic mitral regurgitation (MR). Surgical mitral annuloplasty is limited by morbidity, mortality, and MR recurrence. We evaluated the safety and feasibility of a transvenous catheter-delivered implantable device to provide a percutaneous alternative to surgical mitral annuloplasty. Methods and Results-Five patients with chronic ischemic MR underwent percutaneous transvenous implantation of an annuloplasty device in the coronary sinus. Implantation was successful in 4 patients. Baseline MR in the entire group was grade 3.0Ϯ0.7 and was reduced to grade 1.6Ϯ1.1 at the last postimplantation visit when the device was intact or the last postprocedural visit in the patient in whom the device was not successfully implanted. Separation of the bridge section of the device occurred in 3 of 4 implanted devices and was detected at 28 to 81 days after implantation. There were no postprocedural device-related complications. Conclusions-Percutaneous
