Echo images were received and reviewed.Customer report of moderate paravalvular leak (pvl) can not be confirmed through echo images provided.The device was returned for evaluation.Customer report of "moderate paravalvular leak (pvl) was detected due to a loose stich" was unable to be confirmed through visual observations.As received, all three leaflets were dehydrated.Suture holes were observed around the sewing ring.No sutures were attached to the sewing ring.X-ray demonstrated wireform intact.Wireform was exposed on commissure 1.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.Device dehiscence or suture torn out may occur early or late.When it occurs in the intraoperative period, it is typically a result of inadequate device implantation in combination with friable myocardial tissue.Valve dehiscence is not a malfunction related to a manufacturing deficiency of the device.The instructions for use (ifu) have been reviewed and no inadequacies have been identified with regard to warnings, contraindications, and the directions/conditions for the successful use of the device.The reported type of event is included in the ifu.The most likely cause is procedural factors, including a loose stitch, as reported.
