Medtronic received information via literature regarding unfortunate consequences of mitral valve repair with ring or band implantation.The study population included 29 patients (predominantly male; mean age 61 years), four of which were implanted with medtronic duran ring and one of which was implanted with medtronic ats simulus semi-rigid band.The serial numbers were not provided.Patient 19: a (b)(6) female with atrial fibrillation, systemic hypertension, secondary functional mitral valve regurgitation, and coronary artery disease was implanted with a duran ring.Six years post-implant the patient was noted with mitral stenosis and regurgitation.The ring was explanted and a mechanical valve implanted.The explanted ring showed a portion of the mitral leaflet attached to the ring causing partially obstructing the orifice.No additional adverse patient effects were reported regarding medtronic product.
