Initial results of the chordal-cutting operation for ischemic mitral regurgitation Michael A. Borger, MD, PhD, Patricia M. Murphy, MD, Asim Alam, MD, Shafie Fazel, MD, PhD, Manjula Maganti, MSc, Susan Armstrong, MSc, Vivek Rao, MD, PhD, Tirone E.

Figure 1 Grade of MR preoperatively and during follow-up in the control group (left) and the chordal-cutting group (right). Both groups showed a significant reduction in the grade of MR from before to after surgery (P < .001). Preoperative MR grade was similar between groups, but postoperative MR grade was lower in the chordal-cutting group (P = .04). MR, mitral regurgitation.

Figure E1 Survival (±SEM) after MV repair for IMR in patients undergoing annuloplasty alone (control) versus annuloplasty plus division of secondary chords (chordal cutting). MV, Mitral valve; IMR, ischemic mitral regurgitation.

Figure E2 Event-free survival (±SEM) in patients undergoing annuloplasty alone (control) versus annuloplasty plus division of secondary chords (chordal cutting). Event-free survival was defined as freedom from death, recurrent moderate or more MR, reoperation, thromboembolism, hemolysis, major hemorrhage, or endocarditis. MR, mitral regurgitation.
