Elegant experimental work has helped in understanding the pathogenesis of chronic ischaemic mitral regurgitation (IMR), which appears to be the consequence of a combination of two distinct anatomical abnormalities.1 Globally, annular dilatation occurs secondary to left ventricular (LV) enlargment, causing incomplete coaptation of the mitral valve despite normal leaflet motion. Locally, inferior wall remodelling produces papillary muscle displacement with restricted motion of the mitral leaflets.
Chronic IMR, an independent predictor of mortality with a reported survival of 40–60% at 5 years,2–5 is a progressive disorder in which MR-related LV volume overload promotes further LV remodelling, leading to worsened MR. Therefore, surgical correction, either by replacement or repair, is recommended for 3+ and 4+ IMR.6 Furthermore, repair, as compared with replacement, appears to benefit most patients with IMR, with the possible exceptions of very high hisk group, such as patients in New
