Mitral Regurgitation (MR) is one of the most prevalent valvular disorders in the United States, with a prevalence of ~1.7% [1] and its etiology may be primary or secondary. Secondary MR, also known as functional MR described in patients with left ventricular dysfunction results from annular dilation and alternation in the left ventricular geometry, with mitral-valve-leaflets being structurally normal [2]. The severity of MR in heart failure patients is strongly associated with increased all-cause mortality and readmission rates [3].
