Chronic ischemic mitral regurgitation (IMR) is recognized as functional regurgitation and a common cause of congestive heart failure caused by the myocardial infarction remodeling process. IMR is a strong predictor of poor outcomes in patients with ischemic cardiomyopathy.

Various types of mitral valve repair (MVR) techniques, such as annuloplasty,1Go the edge-to-edge technique,2Go and chordal cutting, have been reported. However, these procedures have yet to result in clearly improved patient outcomes, and the best surgical intervention is still controversial. Therefore the development of new techniques is necessary for better results in patients with IMR. Conventional MVR procedures, such as edge-to-edge repair or repair with an artificial chordae with an undersized ring were original options; however, satisfactory results were not obtained because of recurrent mitral regurgitation and late death. In this article we introduce our new simple procedure, the so-called sandwich plasty.

Clinical Summary

Sandwich plasty is usually performed through a left atrial incision under cardiac . . . [Full Text of this Article]
