Event or Problem Description
|
|
Medtronic received information that one month following the implant of this transcatheter pulmonary bioprosthetic valve (tpbv), the patient was diagnosed with endocarditis and antibiotics were administered.The infective organism was viridans streptococcal and resulted in trivial stenosis and mild regurgitation.Three years following the implant of the valve, the patient presented with a fever.Endocarditis was suspected, but not confirmed.Four blood culture were negative; however, antibiotics were prescribed.Mild pulmonary regurgitation was notes but had not worsened since the previous echocardiogram.No additional adverse patient effects were reported.

Additional Manufacturer Narrative

The device history record was reviewed and showed that this product met all manufacturing specifications for product released for distribution.No issues were identified that would have impacted this event.A review of the sterility lot record confirms that the biological indicators (bi) tested negative for both tissue and solution.There have been no additional complaints, or complaints for infection against any of the devices manufactured under this sterility lot.The sterilization process used by medtronic has an anti-microbial kill on the microorganisms such as staphylococcus and streptococcus species.This process was validated using the worst case bacillus atrophaeus (gram positive spore forming rods), which was known to be representative of the cleanroom bioburden.The information received also indicated that the endocarditis occurred one year post implant.Endocarditis that occurred within two months af ter the procedure are called early prosthetic-valve endocarditis, and are usually acquired while the patient is in the hospital (nosocomial infection).These cases could also be due to introduction of the microorganism during the implant procedure.Dental hygiene may have contributed to the reported endocarditis at one month post implant and resulted in the reported stenosis and regurgitation.Based on the above investigation, the endocarditis was unlikely to be attributed to the device and/or manufacturing process.At three years post implant, the suspected endocarditis was not confirmed as blood cultures were found negative.No conclusion can be made to the reported regurgitation.If information is provided in the future, a supplemental report will be issued.
