It was learned via the implant patient registry and medical records that an 11500a 21mm inspiris resilia aortic valve, implanted for five (5) days, was explanted due to dehiscence caused by annular patch detachment due to friable tissue.The patient presented with hypoxia.The patient is a known case of recent endocarditis.The explanted device was replaced with an 11500a 21mm inspiris resilia valve.The patient is s/p avr due to endocarditis and cad.On pod # 4 the patient developed hypoxia and required intubation.His tee showed a new vsd, and aortic perivalvular leak.He was taken back to or emergently.The surgeon noticed that the pericardial patch that was used to close the abscess cavity is now detached and have caused the newly implanted valve to dehisce from the annular tissue.Simultaneously, the patient had tvr utilizing a non-edwards valve and vsd closure.The patient tolerated the procedure well and was and transferred to the icu in a stable condition.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.

The investigation is still in progress; therefore, a conclusion has yet to be established.A supplemental report will be submitted accordingly upon investigation completion.Edwards will continue to review and monitor all reported events.Trends are monitored on a monthly basis and if action is required, appropriate investigation will be performed.

The device history record was reviewed and shows that this device met all manufacturing specifications for product release prior to distribution.No issues were identified that would have impacted this event.Device dehiscence may occur early or late.When it occurs in the early post-operative period, it is typically a result of inadequate device implantation in combination with friable myocardial tissue.Late dehiscence can occur as a result of successive dilatation of cardiac structures that result from progression of disease.Valve dehiscence is not a malfunction of the device.Through further investigation, it was determined that the root cause of this event was most likely cause is patient factors, including the annular patch detachment due to friable tissue of the patient.
