Tuesday, March 08 2016 @ 05:13 EET
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. 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 of MR.
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.  [...]View full article
