Chronic Ischemic Mitral Regurgitation: Insights into Pandora's Box
Chronic ischemic mitral regurgitation (cIMR) remains a vexing problem for a large number of patients and their respective clinicians. It is estimated that approximately 2 million Americans suffer from cIMR, and this number is likely to increase with an aging general population and improved survival rates for myocardial infarction1. Despite the large number of patients with this disease, relatively few patients are referred for surgical therapy. This is reflected in the fact that the largest surgical series to date consist of only a few hundred patients operated on over a several year interval2,3.
