Additional Manufacturer Narrative
Per the instructions for use (ifu), valve thrombosis is a potential risk associated with the use of the transcatheter heart valves (thv).Use of the sapien transcatheter heart valves (all models) is contraindicated in patients who cannot tolerate an anticoagulation/antiplatelet regimen.In addition, it warns that valve recipients should be maintained on anticoagulant/antiplatelet therapy, except when contraindicated, as determined by their physician.Thrombosis is a rare and well-recognized complication associated with the use of bioprosthetic heart valves.Valve thrombosis is the formation of significant blood clots forming on the valve.Potential patient risk factors such as atrial fibrillation, systemic disease (e.G., systemic lupus erythematosus, inflammation, and damage to various body tissues, including joints, skin, kidneys, heart, lungs, blood vessels, and brain),pharmacological therapies that quickly increase hemoglobin levels, the valvular disease itself, and reduced cardiac ejection fraction can contribute to increased risk of thrombus/thrombosis.Sub-optimal anticoagulation during the procedure and underlying patient conditions can also result in increased thrombogenicity.These patients are anticoagulated for the procedure and interventional best practices mandate meticulous preparation, aspiration, and flushing of the devices to prevent and/or remove clot(s).Short-term anticoagulation therapy may also be necessary after valve repair, anticoagulation is prescribed per institutional guidelines.Intra-procedural intra-cardiac thrombus and post- procedure or late valve thrombosis are complex processes triggered by the interaction between the host and the device which are highly variable among patients.It is the natural tendency of the body to form a clot on foreign objects in the vascular space and a definitive root cause cannot always be confirmed.The device training manuals instruct the operator to consider all procedural and anatomical factors.Edwards extensively trains physicians before they are qualified to use the device system.Training includes patient screening, device preparation, approach, deployment, imaging, procedure-specific training manuals, and proctored procedures.Operators are also instructed to use fluoroscopy in conjunction with echocardiography for optimal visualization during positioning and deployment and cautions include the maintenance of the patient's anticoagulation status (act at greater than 250 seconds) during the procedure in order to prevent thrombosis.In this case, there was no allegation or indication a product malfunction contributed to this adverse event.Investigation results indicate the cause of the event is unknown due to the limited information available a review of edwards lifesciences risk management documentation was performed for this case.The reported event is an anticipated risk of the transcatheter heart valve procedure, additional assessment of this adverse event is not required at this time.The ifu and training manuals have been reviewed and no inadequacies have been identified with regards to warnings, contraindications, and the directions/conditions for the successful use of the device.Complaint histories for all reported events are reviewed against trending control limits monthly, and any excursions above the control limits are assessed and documented as part of this monthly review.As such, neither a product risk assessment, nor corrective or preventative actions are required at this time.
Event or Problem Description
As reported by a field clinical specialist (fcs), approximately 2 years and 3 months post-implant of a 26 mm sapien 3 ultra valve in the aortic position via transfemoral approach.It was initially reported that the valve failed due to stenosis with a suspected halt and gradient of 30mmhg.According to the medical records, the patient was diagnosed with endocarditis and after 6 weeks of antibiotics will repeat cultures.The team is planning for tavr in tavr once cleared by infectious disease (id).Additional information received, cta review observed severe halt with hemodynamic consequence.In a symptomatic patient, this is not subclinical leaflet thickening and was consistent with valve thrombosis.The patient was treated with a non-ew valve.The patient did well and was stable in the recovery area post retreatment.
