Mechanism of recurrent ischemic mitral regurgitation after annuloplasty: continued LV remodeling as a moving target.

Background: Patients who undergo ring annuloplasty for ischemic mitral regurgitation (MR) often have persistent or recurrent MR. This may relate to persistent leaflet tethering from left ventricle (LV) dilatation that is not relieved by ring annuloplasty. Therefore, the purpose of this study was to test the hypothesis that recurrent MR in patients after ring annuloplasty relates to continued LV remodeling.

Failure of reduction annuloplasty for functional ischemic mitral regurgitation.

Background And Aim Of The Study: The standard treatment for functional ischemic mitral regurgitation (FIMR) is revascularization and reduction annuloplasty. Although the immediate results are excellent, some patients develop recurrent mitral regurgitation (MR) at mid-term follow up. The study aim was to identify possible preoperative echocardiographic parameters that might predict the risk of recurrent FIMR.

Outcome after mitral valve repair for functional ischemic mitral regurgitation.

Background And Aim Of The Study: Functional ischemic mitral regurgitation (MR) can occur secondary to coronary artery disease. Controversy exists regarding management of these patients. Mitral valve annuloplasty in conjunction with coronary artery bypass grafting (CABG), accepted as the best treatment for severe MR, has been disputed for lesser degrees of regurgitation due to higher mortality.
