This report provides data from thv/tvt registry exemption number e2016006 and summarizes 2 device embolization death events for the sapien 3 ultra transcatheter heart valve in the aortic position.The "time to event" (tte, in days) for this event was 0.5.The device identification (di) numbers for edwards sapien 3 ultra transcatheter heart valve are: (b)(4).Per the instructions for use, valve embolization is a known potential adverse event associated with the tavr procedure.There are multiple patient and procedural factors that alone or in combination can cause or contribute to aortic embolization, including improper positioning prior to deployment, poor image intensifier angle, poor coaxial alignment of the valve and delivery system, severe septal hypertrophy, minimally or bulky/severely calcified aortic leaflets, preserved ejection fraction, loss of pacing capture, rapid deployment, 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 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 to 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), bav may provide indication of potential balloon movement during valve deployment.In this case, there was no allegation or indication a product malfunction contributed to this adverse event.Specific clinical and procedural details are not available to determine potential contributing factors to the event, or if the event is related to an edwards device.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 on a monthly basis, and any excursions above the control limits are assessed and documented as part of this monthly review.No corrective or preventative actions are required.
