    Description of Event or Problem · 1

    MEDTRONIC RECEIVED INFORMATION VIA LITERATURE REVIEW OF A RETROSPECTIVE STUDY PERFORMED TO EVALUATE THE TIMING, DIAGNOSTIC CRITERIA, AND TREATMENT STRATEGIES FOR THROMBOSIS IN BIOPROSTHETIC VALVES. THE STUDY POPULATION INCLUDED DATA FROM 31 PATIENTS (PREDOMINANTLY FEMALE; MEAN AGE 60 +/- 17 YEARS) FROM ONE CENTER BETWEEN 1997 AND 2013. FIFTEEN OF THESE PATIENTS WERE IMPLANTED WITH MEDTRONIC BIOPROSTHETIC VALVES FROM TWO DEVICE FAMILIES (SERIAL NUMBERS NOT REPORTED) IN THE AORTIC/ATRIO-VENTRICULAR (N=8), MITRAL (N=6), AND PULMONARY (N=1) POSITIONS. PATIENT 15 (FEMALE, (B)(6)) WAS IMPLANTED WITH A MEDTRONIC 31-MM BIOPROSTHETIC VALVE IN THE MITRAL POSITION. THROMBOSIS WAS DIAGNOSED 167 DAYS POST-IMPLANT. FURTHER EVALUATION REVEALED A LARGE MOBILE THROMBUS WHICH WAS TREATED SURGICALLY. NO ADDITIONAL ADVERSE PATIENT EFFECTS WERE REPORTED. ADDITIONAL INFORMATION HAS BEEN REQUESTED.
