Secondary Mitral Regurgitation: Diagnosis and Management.

Secondary mitral regurgitation is one of the most common valve diseases. The disease is a result of left atrial or left ventricular dysfunction. It is generally classified into stages based on its severity. While surgical intervention does not confer improved survival in this subset of mitral disease, recent advances in transcatheter interventions have resulted in improved survival and symptomatology in carefully selected patients. In this review, the multimodality imaging evaluation of the mitral valve and secondary mitral regurgitation is discussed. Commercially available and investigational transcatheter interventions for secondary mitral regurgitation management are also reviewed.
