On (b)(6) 2021, a perceval valve pvs21 was attempted to be implanted.The preoperative ct scan showed an aortic valve diameter of 20 mm and st junction diameter of 23 mm.The s-sizer white obturator did not pass through stj and valsalva.When the size was confirmed again with reference to the transparent obturator of s-sizer, it was confirmed that the annulus was large enough for the white obturator to pass through.Perceval size s was selected and the product was implanted.No abnormality was observed visually at the time of implant.After implanting, echocardiography showed pvl between the left coronary cusp and the commissure strut.Pvl was closer to mild than trace.Echo showed that it was difficult to see due to noise and artifacts, but the indwelling position seemed to be a little high, so the device was removed.After removal, sizing was performed after checking around the annulus, another perceval size s was placed.Echo after reimplantation showed that there was no problem with the indwelling position and no regurgitation, and the surgery was completed.The doctor commented that the malposition of the device may be related to severe calcification at the left ventricular outflow tract, and there was no malfunction of the 1st pvs device.The x-clamp time was extended by 44 minutes due to this event.
