Does chordal cutting associated with complete annuloplasty improve outcomes in patients with chronic ischemic mitral regurgitation?
Chordal cutting combined with complete annuloplasty is a potentially viable surgical option for chronic ischemic mitral regurgitation, showing no perioperative mortality in a small case series.
May support feasibility of chordal cutting with annuloplasty in chronic ischemic MR; hypothesis-generating and requires prospective trials before practice change.
OBJECTIVES: The optimal surgical management of chronic ischemic mitral regurgitation has not yet been clearly defined. Among the various approaches proposed, the excision of strut (or main) chordae, along with complete annuloplasty to relieve tethering, has been the one preferred by our institution to treat this particular subset of mitral disease. METHODS: Between October 2004 and May 2013, 11 patients underwent surgery for chronic ischemic mitral regurgitation. RESULTS: There was no perioperative death. No patient was lost to follow-up. There was one late death due to respiratory failure three years after the operation, and one patient received a ventricular assist device ten months after surgery. The remaining patients are all alive with residual trivial-to-mild regurgitation. CONCLUSION: Chordal cutting associated with complete annuloplasty may be a good surgical option in chronic ischemic mitral regurgitation.

Col et al. (2014) conducted an observational in chronic ischemic mitral regurgitation (n=11). Chordal cutting with complete annuloplasty was evaluated. Chordal cutting with complete annuloplasty for chronic ischemic mitral regurgitation resulted in 0 perioperative deaths, 1 late death, and residual trivial-to-mild regurgitation in survivors.
