Manufacturer Narrative

Product analysis: the device remains implanted, therefore no product analysis can be performed.Conclusion: without the return of the product, no definitive conclusion can be made regarding the clinical observation.Conduction disturbances are known potential adverse effects associated with any cardiac or thoracic procedure (open or catheter-based) and can be resolved with medical treatment or the implant of a permanent pacemaker (with the risk-benefit ratio in favor of implant of the percutaneous aortic valve).A conduction disturbance does not indicate a device malfunction or potential manufacturing issue.If information is provided in the future, a supplemental report will be issued.

Event Description

Medtronic received information that approximately 6 days post implant of this 27mm mitral bioprosthetic valve in the tricuspid position, a permanent pacemaker was implanted due to 3rd degree atrio-ventricular (av) block.No additional adverse patient effects were reported. .
