Event or Problem Description
It was reported that on (b)(6) 2026, a 23 navitor vision valve was selected for implant using a small flexnav delivery system (ds) due to the patient's anatomy with severely calcified aortic valve with tapered left ventricular outflow tract (lvot) and smaller sinus of valsalva (sov).Pre-implant balloon aortic valvuloplasty (pre-bav) was performed by using an 18mm, non-abbott balloon.The valve was loaded and check with x-ray.During the procedure, the physicians used rotation move to make insertion swifter and some resistance was experienced with the flexnav ds.At 80 percent, the valve appeared to be constrained therefore a partial resheath was performed and it was observed that the nose cone was not recaptured completely.On the second attempt, the valve expanded comparatively better but significant paravalvular leak (pvl) was observed then the physician's deemed that the 23mm valve to be undersized and a second 25mm, navitor vision valve was decided to be replaced using a new small flexnav ds.Once the loading was completed, 23mm, navitor vision valve was attempted for recapture but once again the retraction issue persisted while the nose cone being exposed.Ds was retracted into the descending aorta to improve the coaxial alignment.Micro-adjustment wheel was used several times including macro-buttons.At this moment, the valve capsule was observed to be crumpled/wrinkled.It was attempted to remove the ds from the patient's anatomy; however, removal was challenging because the crumpled portion of the ds was too large to pass through the femoral arteries.Upon discussion, it was decided to deploy in the descending aorta.Ds was able to be removed with significant pulling, pushing and rotating.No significant bleeding was observed, and it was attempted to insert the second 25mm, navitor valve with the new small flexnav ds.The ds was not able to be inserted, subsequently a femoral artery dissection was identified.The patient was received general anesthesia (ga) then the artery was implanted with a stent; two units of blood were administered.The procedure was noted to be abandoned.In the physician's opinion wrinkled part of the flexnav ds was thought to be the cause of the femoral artery dissection.On the following day, the patient was extubated and in a recovering condition.
