ABSTRACT Mitral valve regurgitation poses a significant public health burden, with more than 3 million people in the US alone suffering from moderate or severe mitral valve regurgitation. Surgical correction with mitral valve repair or replacement is the mainstay of therapy. However, a significant proportion of elderly patients are not eligible for mitral valve repair or replacement due to prohibitive surgical risk from increased age, poor ventricular function, or associated comorbidities. Percutaneous mitral valve repair/replacement techniques have been developed to fill this void. The most advanced percutaneous technique with the highest safety and efficacy to date is the edge-to-edge MitraClip repair system. The majority of other catheter-based mitral valve repair/replacement devices are at early developmental stages, but have shown encouraging initial results in feasibility trials. Transcatheter mitral valve replacement holds promise to emerge as the leading transcatheter treatment of choice in the fu...
