Abstract

In many ways we are at a crossroad in terms of what constitutes optimal FIMR treatment: is CABG combined with mitral valve ring annuloplasty better than CABG alone in moderate FIMR? Is mitral valve repair really better than replacement? And does adding a valvular repair or subvalvular reverse remodeling procedure shift that balance? In the present thesis I aim to shed further light on these questions by addressing the current status and future perspectives of the surgical treatment of FIMR. CURRENT SURGICAL TREATMENT FOR FIMR. CABG alone: The overall impression from the literature is that patients are left with a high grade of persistent/recurrent FIMR from isolated CABG. CABG is most effective to treat FIMR in patients with viable myocardium (at least five viable segments) and absence of dyssynchrony between papillary muscles (< 60 ms). Mitral valve ring annuloplasty. A vast number of different designs are available to perform mitral valve ring annuloplasty with variations over the theme of complete/partial and rigid/semi-rigid/flexible. Also, the three-dimensional shape of the rigid and semi-rigid rings is the subject of great variation. A rigid or semi-rigid down-sized mitral valve ring annuloplasty is the most advocated tre...Continue Reading
