Ischemic mitral regurgitation (IMR) is a common complication of ischemic heart disease that often leads to an adverse prognosis after myocardial infarction and coronary revascularization. ¹ The present accepted therapy for IMR is to reduce the annular size, thereby making a deep coaptation zone. The efficacy of chordal cutting for IMR was first reported by Messas and associates ^2,3 in 2001. Although this method has been described as a simpler approach to reduce tethering in an experimental study, we thought that cutting a limited number of critically positioned chordae, which restrict leaflet closure, might be an effective surgical modality for repair of IMR in clinical cases. We herein present the case of a patient who was treated with chordal cutting in combination with ring annuloplasty and an overlapping cardiac volume reduction operation, which is a new clinical therapeutic approach for the treatment of IMR.

Clinical Summary

A 69-year-old man with ischemic cardiomyopathy associated with IMR and atrial fibrillation was admitted to our institute in February 2004. He had previously presented with acute myocardial infarction of the left . . . [Full Text of this Article]
