The device was not returned to edwards for evaluation as it remains implanted.Echo imaging was received and reviewed by third party echo imaging expert.Echo imaging impression: the submitted images are of poor quality and, without associated times of acquisition, are difficult to associate with specific surgical intervals.The images document ar after the first pump run, although the mechanism is not defined.The presence or absence of ar was not defined on the submitted pre-pump images, and an interval change cannot be confirmed.With very limited interrogation of the valve, it is unclear whether the appearance of aortic valve leaflet thickening and decreased leaflet motion during the post-pump #1 interval is real (albeit transient) or a function of imaging artifact.The investigation is still in progress; therefore, a conclusion has yet to be established.A supplemental report will be submitted accordingly upon investigation completion.Edwards will continue to review and monitor all events.Trends are monitored on a monthly basis and if action is required, appropriate investigation will be performed.

It was reported that a patient developed aortic regurgitation grade 3 during the surgery that was performed for mitral valvuloplasty with a mitral ring and tricuspid annuloplasty with a 28mm 6200t tricuspid ring.The surgery was performed in the order of mitral valvuloplasty (p3 triangular resection), pulmonary vein isolation, left atrial appendage closure, and tricuspid annuloplasty.After completing all procedures and releasing the aortic clamp, echo showed the aortic regurgitation.Because both ventricles had become swollen due to increased blood volume secondary to the regurgitation, the surgeon decided to perform an additional aortic valve replacement, so the aorta was re-clamped and a 19mm 11500aj aortic valve was implanted.The patient status was reported as recovered.Per the reported information, no sutures used to implant both rings were placed on the aortic side.According to the surgeon, mild ar was observed prior to the surgery, but no issues were confirmed in the aortic valve, such as leaflets thickening or immobility.The surgeon commented it was unknown regarding the causal relationship between this 6200t ring and the event.
