Event or Problem Description
It was learned through implant patient registry and investigated that a patient with a 23mm 8300ab aortic valve was explanted after an implant duration of 7 years, 5 months due to degeneration and stenosis.Patient presented with shortness of breath, chest pain and lightheadedness.The explanted valve was replaced with a 25mm 11500a valve.Patient was transferred to icu and discharged on pod#3.Edwards lifesciences maintains an implant patient registry.This registry is a patient tracking mechanism for serialized edwards implantable devices (bioprosthetic heart valves and annuloplasty rings), rather than a true post-market surveillance registry.Through the registry, edwards is notified when these devices are implanted.In addition, patient and/or device status may be reported to the registry via the implantation data cards.The information is received from various sources (e.G.Surgeon, hospital, and patient family members) and is not received in the form of a conventional 'customer complaint'.The information reported may or may not be related to the edwards device.
