Regional wall motion abnormalities and scarring in severe functional ischemic mitral regurgitation: A pilot cardiovascular magnetic resonance imaging study

In a pilot study of cardiovascular magnetic resonance imaging in severe functional ischemic mitral regurgitation, severity of posterior papillary muscle region scarring correlated with decreased segmental wall motion and mitral regurgitation early after coronary revascularization and annuloplasty. Routinely assessing scar burden may identify patients for whom annuloplasty alone is insufficient to eliminate mitral regurgitation.
