Event Description

Medtronic received information that 3 years and 6 months post implant of this 29mm aortic bioprosthetic valve, it was explanted and replaced with a 27mm bioprosthetic valve of a different manufacturer.The reason for the replacement was reported as prosthetic valve endocarditis and a expanding false aneurysm on the posterior aspect of the bioprosthetic aortic root.It was noted that the patient was asymptomatic.During the procedure, it was observed that the bioprosthetic aortic root was widely disrupted and had ripped through a large proportion of its posterior aspect.It was suspected that the cause of the false aneurysm was failure of the bioprosthetic root due to infection.It was stated that the prosthesis failed because of a large tear in the left coronary sinus outside of the left coronary button which was expanding in a false aneurism posteriorly.The valve along with some pannus tissue from underneath the valve was removed.It was reported that no organism was subsequently cultured and there was no vegetation on the valve.Endocarditis was not confirmed.No additional adverse patient effects were reported.
