The Role of Echocardiography in the Surgical Management of Secondary Mitral Regurgitation


Secondary mitral regurgitation (MR) also known as functional mitral regurgitation is more common, portends a worse prognosis than primary MR and its management is more difficult and less sustained by evidence. [1]The etiology of secondary MR may be ischemic or nonischemic such as in idiopathic dilative cardiomyopathy. The prognosis of patients with secondary MR is worse with increasing severity ofMR.[2]

The mechanism of secondary MR is linked to the left ventricle (LV) geometrical remodeling with secondary tethering of the mitral leaflets, while the valve morphology is normal. [3][4] […]
