On (b)(6) 2021, a perceval valve pvs23 was attempted to be implanted as part of an aortic valve replacement procedure.It was reported that no problems were encountered during the valve sizing, collapsing and parachuting.The perceval valve was correctly deployed on the annulus but difficulties were encountered during the retraction of the transparent sheet of the dual holder to deploy the stent in the aorta.The plastic sheath appeared locked.The surgeon attempted several times, while maintaining the holder and the guiding suture in place.At this point, the valve moved up to the annulus, thus the valve had to be removed.The procedure was repeated and the second time the same difficulties were identified during the valve deployment (same dual holder was used).The surgeon pulled strongly on the transparent sheet and finally the valve was successfully deployed.The toe shows good results.There was an extension of 30min to the extracorporeal circulation, but the patient remained stable during the delay in the procedure.
