Medtronic received information via literature regarding the patient outcomes following mitral valve repair using a three-dimensional saddle-shaped, rigid ring.All data were collected from 7 centers between february 2013 and july 2015.The study population included 148 patients (predominantly male; mean age 64 years), all of which were implanted with medtronic profile 3d annuloplasty rings (no serial numbers provided).Among all patients, 3 deaths occurred (1 cardiac, 2 non-cardiac).Two deaths occurred within 30 days post implant and 1 death occurred more than 30 days post implant.All 3 deaths were considered ¿possibly related to the implant procedure.¿ based on the available information, medtronic product may have been associated with the deaths.Among all patients, adverse events included: explant due to ring dehiscence (1 case) and early recurrence of mitral insufficiency (1 case).Other adverse events reported: conversion to mitral valve replacement surgery (2 cases for unknown reasons), major stroke, minor stroke, myocardial infarction, ring dehiscence, major hemorrhage, minor hemorrhage, atrioventricular block (first-, second-, and third-degree), left ventricular outflow tract obstruction, worsening of mitral insufficiency, mild-moderate-severe mitral regurgitation, pericardial effusion, pleural effusion, atrial fibrillation, atrial flutter, bradycardia, junctional rhythm, left and right bundle branch block, sick sinus syndrome, tachycardia (supraventricular and ventricular), and ventricular fibrillation.Based on the available information, medtronic product was directly associated with the adverse events.No additional adverse patient effects or product performance issues were reported.
