Medtronic received information that this patient presented to the hospital following non-st segment myocardial infarction (nstemi).Upon admission the patient required an intra-aortic balloon pump (iabp).The patient was then taken for emergent mitral valve surgery and coronary artery bypass grafting (cabg).The patient's native mitral valve had a torn papillary muscle resulting in a flail anterior and posterior leaflet and severe regurgitation.A medtronic mitral annuloplasty ring was used in conjunction with neochords in an attempt to repair the native mitral valve.It was reported that initially the repair appeared to be successful, but after removing the cross-clamp, moderate to severe residual mitral regurgitation was noted.As a result, the annuloplasty ring was explanted and replaced with a non-medtronic bioprosthetic valve.The patient was supported via venous-arterial extracorporeal membrane oxygenation (ecmo) and the pre-existing iabp at the conclusion of the operation.No additional adverse patient effects related to a medtronic device were reported. .
