Transcatheter therapies have progressively assumed a major role in the treatment of valve heart disease. The major drivers have been population ageing, the high prevalence of valve disease in the elderly, and the consequent need of less invasive treatments for this fragile patient population. While transcatheter aortic valve implantation (TAVI) has achieved a central role in the treatment of severe aortic stenosis across any surgical risk category, transcatheter treatment of mitral valve disease is still the object of intense debate and investigation. The reasons are that the mitral valve apparatus anatomy is more complex, involving valve leaflets, subvalvular apparatus and the left ventricle. Further, the most frequent mitral valve disease, i.e. mitral regurgitation, has different etiologies and is frequently a consequence rather than the cause of left ventricular dysfunction and heart failure. Hence, clinical efficacy of its correction is uncertain. Beyond the varying clinical scenarios, there are a miriad of devices under developement or at different stages of clinical investigations. This book describes the state of the art in the filed of percutaneous treatment of mitral valve disease. It provides a comprehensive review including anatomical basis, in-depth diagnostics, patophysiology, summary of available evidence for transcatheter treatments, state-of-the art of cardiac surgery,description of devices commercially available or under investigation, and clinical examples.

21/01/2015ย ยท Percutaneous mitral valve repair (MVR) is used to treat mitral regurgitation (MR; depicted in the image below). Percutaneous procedures used to treat valvular heart disease were first developed decades ago; the first pulmonic balloon valvuloplasty was reported in 1982 and was quickly followed by applications to the aortic and mitral valves. 09/07/2010ย ยท The percutaneous management of valvular heart disease has recently been receiving a great deal of interest as an area of great potential. Innovative technologies are now being developed to treat mitral regurgitation. Although there are established surgical techniques for treating organic mitral regurgitation, the surgical management of functional mitral regurgitation remains controversial, and

However the available approaches mainly contribute to alleviate the symptoms and are suitable for very specific forms of mitral valve disease and anatomic subset. The possibility to perform a complete percutaneous mitral valve replacement still represents an unmet need which would provide enormous advance for a vast patients population.

Percutaneous mitral valve edge-to-edge repair has evolved into a therapeutic option for high surgical risk patients with severe functional MR as well as insufficiency secondary to prolapse or 09/10/2012ย ยท Surgical approaches to correct mitral regurgitation (MR) have evolved over 50 years and form much of the basis for percutaneous approaches to the mitral valve. Surgical mitral repairs have been more durable with use of annuloplasty, but recurrent regurgitation not resulting in reoperation can occur. The mitral leaflets may be resected or augmented, with recent trends to preserve leaflet
