This report provides data from thv/tvt registry exemption number e2016006 and summarizes 1 reintervention - mitral valve event for the sapien 3 ultra transcatheter heart valve in the mitral position.The ''time to event'' (tte, in days) for this event was 156.The device identification (di) numbers for edwards sapien 3 ultra transcatheter heart valve are: (b)(6).Intra-procedural and in hospital mitral valve re-intervention will typically result from valve malposition or regurgitation (pvl or central, including leaflet restriction).These conditions are known potential risks associated with the use of the thv, delivery system, and/or accessories.There are multiple patient and procedural factors that alone or in combination can cause or contribute to valve malposition, including improper positioning prior to deployment, poor image intensifier angle, poor coaxial alignment of the valve and delivery system, characteristics of the pre-existing valve or ring, loss of pacing capture, rapid deployment, release of stored tension during deployment, and movement of the delivery system by the operator.Valve malposition has the potential to contribute to suboptimal coaptation of the thv valve leaflets and cause central aortic insufficiency; it can lead to migration or embolization of the prosthesis.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 this case, specific procedural details are not available to determine potential contributing factors.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.H3 other text : summary report.
