Echocardiographic quantification of mitral valvular response to myocardial revascularization

Abstract

There was no change in the mitral valve NPA with revascularization alone in patients with mild or moderate IMR. Mitral valve does not change its planarity (NPA) with revascularization alone in patients with IMR.

The saddle shape of the mitral valve: More than just a shape

“…[18] The authors hypothesized that these patients after myocardial revascularization alone will show a decrease in NPA with or without changes in other geometric parameters. Apparently, the hypothesis that the mitral annulus NPA will recover after myocardial revascularization assumes that the loss of saddle shape or non-planarity of the MV annulus is because of myocardial dysfunction, and revascularization would improve myocardial functions and restore or improve non-planarity of the MV annulus.…”

Three‐Dimensional Transesophageal Echocardiographic Study of Aortic‐Mitral Valve Coupling after Coronary Artery Bypass Grafting

“…considered that an improved LVEF was the main cause of improved ischemic MR after CABG. Govindan et al . reported no significant change in the nonplanar angle of the MV after revascularization in patients with mild or moderate ischemic MR.…”
