Event Description

Literature was reviewed regarding extensive aortic root endocarditis with extension into the intervalvular fibrous body. the study population included 60 patients who were predominantly male with a mean age of 61 years.  multiple manufacturer¿s devices were implanted in the study population; 42 patients were implanted with a medtronic freestyle bioprosthetic aortic root (n=37), hancock ii aortic bioprosthetic valve (n=1) or simulus annuloplasty ring (n=4) for mitral valve repair. deaths occurred in the study population; however, there was no statement establishing a causal or contributory relationship between medtronic product and the deaths.  among all patients adverse events included: infective endocarditis, bleeding complication, paravalvular leak, mitral regurgitation, pseudoaneurysm, arrhythmia requiring permanent pacemaker implant, congestive heart failure, moderate valvular stenosis, acute kidney injury, and re-intervention some of which required mechanical circulatory support with extracorporeal membrane oxygenation or intra-aortic balloon pump. no further information pertaining to medtronic products was noted.
