Additional Manufacturer Narrative
H11: additional manufacturer narrative: 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.
Event or Problem Description
It was learned through implant patient registry and medical records that a patient with a 25mm 6900ptfx mitral valve was explanted after an implant duration of 3 years, 9 months due to calcification, vegetation, immobile leaflets, and severe stenosis.The explanted valve was replaced with a 29mm 11400m valve.The patient was taken to the icu in stable condition post procedure.Per medical records, pre-op tee showed vegetation on mitral valve with moderate stenosis and poorly mobile leaflets.Redo sternotomy was performed to explant the 25mm plus mitral valve and replace with a 29mm mitris.Intra-operatively, the mitral valve was found to be severely diseased beyond repair.Valve was removed and posterior leaflet was debrided to accommodate a larger valve and reduce obstruction.Post-op tee revealed stable rv/lv function and confirmed new mitral valve was well seated with mobile leaflets.The patient was taken to the icu in stable condition post procedure.Per pathology report, the explanted mitral valve was received with possible calcifications and trace fibrous tissue attached to the ring of the valve.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.
Additional Manufacturer Narrative
H11: additional manufacturer narrative: updated sections d4 (expiration date), h4, h6 (investigation findings, investigation conclusions).Svd: svd is a logical and expected consequence of the chemical, mechanical, and immunological processes associated with bhv implantation.The common endpoint of all these factors is calcification and degradation.Svd is an acquired condition, intrinsic to bioprosthetic valves, characterized by deterioration of the leaflets or supporting structures, leading to thickening, calcification, tearing, or disruption of the prosthetic valve materials.These changes result in valvular dysfunction manifesting as stenosis and/or regurgitation with a consequent drop in hemodynamic efficacy of the valve.Prior investigations and extensive literature review have shown that svd is predominantly related to patient factors and implant duration rather than to manufacturing issues.Events related to device design, manufacturing, or use error tend to manifest at an earlier implant duration.There is no evidence to suggest a manufacturing defect caused or contributed to the reported event.Based on the information available, the root cause remains indeterminable as no patient or procedural factors known to cause or contribute to svd were reported.Late endocarditis: intermediate/late onset endocarditis (greater than 60 days post-implant) occurs due to the implant being seeded from an infection or microbial contamination from elsewhere in the patient's body and is not in any way related to the sterilization or packaging process of the device.The microorganism for intermediate/late onset prosthetic device endocarditis may be due to hospital-acquired infections of lower pathogenicity or community-acquired infections.Common sources of endocarditis include dental, surgical, or endoscopic procedures; iv drug abuse; or recurrent endocarditis.There is no evidence to suggest a manufacturing defect caused or contributed to the reported event.Based on the information available, the most likely cause is patient factors.The subject device is not available for evaluation as attempts were made to retrieve the device, but no device was returned.The device history record (dhr) review was completed, and this device passed all manufacturing and sterilization inspections prior to release for distribution.There were no issues identified that would have impacted this event.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.H11: corrected data: corrected section h6 (type of investigation).
