Medtronic received information via literature regarding a (b)(6)-year-old male patient with hypertension, hyperlipidemia, coronary artery disease, ischemic cardiomyopathy, a history of triple coronary artery bypass surgery in 2004, ascending aortic aneurysm repair and aortic valve replacement for severe aortic stenosis in 2012 using a 29-mm medtronic freestyle aortic root bioprosthesis (unique device identifier numbers not provided).In 2015, the patient developed acute severe aortic regurgitation from a tear in the freestyle left cusp.The patient underwent transcatheter valve-in-valve (viv) implantation of a 29-mm medtronic corevalve bioprosthesis (unique device identifier numbers not provided).In 2019, the patient was hospitalized with acute severe heart failure and pulmonary edema.Transesophageal echocardiography (tee) revealed high transvalvular gradients, severe central aortic regurgitation, secondary severe mitral regurgitation and pulmonary hypertension.The patient underwent transcatheter aortic valve-in-valve-in-valve replacement with a non-medtronic bioprosthesis and was later discharged from the hospital with improved symptoms.No additional adverse patient effects or product performance issues were reported.
