The role of noninvasive imaging to help guide transcatheter aortic valvular interventions is well established and has grown with the advances in the procedure. With the rapid development of new transcatheter mitral valve interventions there is both an opportunity and a challenge for noninvasive imaging to grow understanding of mitral valve anatomy and disease, help with patient selection, and improve downstream clinical outcomes. This review will discuss the role of both echocardiography and multidetector CT in the diagnosis of mitral regurgitation, as well as grading of its severity and defining its etiology. Additionally, new concepts including measurements pertaining to mitral annular sizing, segmentation of mitral annular calcium, prediction of neo-left ventricular out flow tract obstruction, hybrid or fusion multidetector CT/echocardiographic imaging, and CT-based fluoroscopic guidance will be discussed.

Transcatheter mitral valve replacement is an emerging technology for the treatment of mitral valve regurgitation. Numerous devices are in development and in various stages of clinical investigation. T...
Mitral regurgitation is the most common valve disease in the United States. This article focuses on a new percutaneous mitral valve treatment for chronic degenerative mitral regurgitation.
Mitral regurgitation is considered the most prevalent valve disease in the United States and its incidence is increasing due to the aging population. Surgical mitral valve repair and replacement are e...
Improvements in symptoms, functional capacity, and quality of life are among the key goals of edge-to-edge transcatheter mitral valve repair (TMVR) for mitral regurgitation.
Valvular heart disease is an important cause of morbidity and mortality throughout the world; in industrialized nations, mitral regurgitation (MR) is the most common valvular lesion. Untreated, severe...

Backflow of blood from the LEFT VENTRICLE into the LEFT ATRIUM due to imperfect closure of the MITRAL VALVE. This can lead to mitral valve regurgitation.
Abnormal protrusion or billowing of one or both of the leaflets of MITRAL VALVE into the LEFT ATRIUM during SYSTOLE. This allows the backflow of blood into left atrium leading to MITRAL VALVE INSUFFICIENCY; SYSTOLIC MURMURS; or CARDIAC ARRHYTHMIA.
A type of heart valve surgery that involves the repair, replacement, or reconstruction of the annulus of the MITRAL VALVE. It includes shortening the circumference of the annulus to improve valve closing capacity and reinforcing the annulus as a step in more complex valve repairs.
Narrowing of the passage through the MITRAL VALVE due to FIBROSIS, and CALCINOSIS in the leaflets and chordal areas. This elevates the left atrial pressure which, in turn, raises pulmonary venous and capillary pressure leading to bouts of DYSPNEA and TACHYCARDIA during physical exertion. RHEUMATIC FEVER is its primary cause.
Surgical treatment for severe AORTIC VALVE STENOSIS. Transcatheter aortic valve replacement (TAVR) is used as an alternative option in patients who are deemed at high risk or inoperable for traditional open-heart surgery.
