The manufacturer was informed that percival heart valve size 27 was implanted and explanted intra-operatively on (b)(6) 2022.Reportedly, the annulus diameter was 28.8mm on preoperative ct.During the sizing procedure, the xl white obturator was moderately resistant, so the xl size valve was implanted.However, after de-clamp, echo showed paravalvular leakage.After re-clamp, it was found that the part of the device has fallen to the lvot side.As such, device was explanted and epic 27mm was implanted instead.Based on the medical judgement received, the fall of the device was probably due to a larger native annulus.More than 20 minutes was added to the cross clamp time as a result of the reported event.Based on the information received, there was no concomitant procedure and echo is unavailable.There was no positioning difficulty, no abnormal geometry in the patient's annulus, and no problem with the device functionality.
