Key result
Papillary muscle relocation with a multiloop suture is proposed as a surgical technique for ischemic mitral regurgitation.
Why the study?
Recurrence of ischemic mitral regurgitation is seen in up to 58.8% of patients at 2 years after revascularization via CABG and restrictive annuloplasty.
Proposes a surgical technique using a multiloop suture for papillary muscle relocation to address ischemic mitral regurgitation.
MR recurrence persists after CABG+RA for IMR; leaves open need for refined techniques in prospective studies.
Ischemic mitral regurgitation (IMR), a subtype of functional MR, occurs when mitral valve leaflets cannot adequately coapt in the absence of structural abnormalities. Functional MR is associated with increased morbidity and mortality.1 Ischemia causes left ventricular remodeling, annular dilatation, and poor leaflet coaptation. Treatment involves revascularization via coronary artery bypass grafting (CABG) and mitral valve repair via restrictive annuloplasty (RA). Recurrence of MR is still seen in up to 58.8% of patients at 2 years postoperatively.
