Event or Problem Description
Additional information was received that prior to the pre-implant bav and before the aortic dissection was identified, the first delivery catheter system (dcs) was inserted into patient; however, the dcs was unable to cross the aortic valve.Subsequently, the dcs was withdrawn from the patient, and the pre-implant bav was performed to help steer the dcs through the valve.A decision was made to use a new valve and new dcs due to the difficulty crossing the valve, and the amount of pressure that was being applied to the system.Per the physician, both dcs and both valves did not cause or contribute to the dissection as the dissection occurred after the pre-implant bav.
Additional Manufacturer Narrative
