As reported, during the transfemoral tavr procedure for a 26mm sapien 3 valve, the valve embolized into descending aorta.The valve was deployed in an aorta with 2ml less than nominal volume because the patient was moving a lot during the valve deployment.During post dilation to modify the valve expansion, the pacing was missed for one beat, and the sapien 3 valve with the balloon detached from the native aortic valve cusps and moved to aorta.The valve was fixed with a stent graft and remained embolized at the descending aorta.A second valve was deployed.

Device remains implanted.Per the instructions for use (ifu), valve embolization is a known potential adverse event associated with the transcatheter valve replacement (thv) procedure.There are multiple patient and procedural factors that alone or in combination can cause or contribute to aortic embolization, including improper positioning before deployment, poor image intensifier angle, poor coaxial alignment of the valve and delivery system, severe septal hypertrophy, minimally or bulky/severely calcified leaflets, preserved ejection fraction, loss of pacing capture, rapid deployment, the release of stored tension during deployment, and movement of the delivery system by the operator.The thv training manuals instruct the operator on proper positioning and deployment of the valve, including all procedural and anatomical considerations.Physicians are extensively trained by edwards before they are qualified to use the sapien thv.Training includes patient screening, device preparation, approach, deployment, imaging, procedure-specific training manuals, and proctored procedures.The correct alignment and positioning of the device at the point of deployment is emphasized as a key factor in the placement and fixation of the device.Operators are also instructed to use fluoroscopy as the primary method of visualization for positioning and deployment.In patients with high-risk anatomical features for aortic embolization (i.E.Minimal leaflet calcification, severe septal hypertrophy), bv may indicate potential balloon movement during valve deployment.Per the instructions for use (ifu), (add adverse event name) is a potential adverse event associated with the transcatheter valve replacement (tvr) procedure and the use of the edwards thv devices.In this case, there was no allegation or indication a product malfunction contributed to this adverse event and the event is considered to be related to patient/procedural factors.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.No corrective or preventative actions are required.Device remains implanted.
