As reported by an edwards france affiliate, during a transfemoral tavr procedure with a 26mm sapien 3 ultra valve, there were difficulties trying to advance the commander delivery system and valve through the esheath beyond the right external iliac artery.The valve did not exit the tip of the esheath and was observed to be angulated on imaging (without damage or distortion of the valve).It was decided to retrieve the valve through the esheath, but on imaging, the pusher was noted to be pulled back creating a gap between the pusher and the valve.Therefore, the decision was made to remove the devices (esheath and commander ds with valve) as a unit, but this was unsuccessful.It was believed that the valve had exited the side of the esheath causing vascular damage.Bav was performed to help alleviate the aortic stenosis.An abdominal cutdown was performed and the patient remained stable with medication to maintain blood pressure.An abdominal aortogram showed no flow down the right leg.With effort, the delivery system with esheath were attempted to be removed together, but the valve remained inside the patient caught in the right external iliac artery.The esheath and delivery system were removed, and there was no bleeding or extravasation observed on aortogram.When reviewing the retrieved device, it was noticed that the delivery system tip and balloon had embolized.The patient then became hypotensive and cpr was started.Imaging showed there was little to no blood being pumped out of the right ventricle and almost no cardiac output.The patient had lost about 2l of blood from the cutdown and received 4 units of blood and fluids iv.The return of perfusion of the leg created lactate and potassium wash out returning to the heart, causing a drop in blood pressure which potentially aggravated the right ventricular dysfunction.After about 40 minutes of cpr, the patient passed away.As per medical opinion, the death was related to the ischemic spiral caused by the return of blood flow to the right leg creating the wash out effect, poor right ventricular ejection, and little to no reserve related to poor right ventricle and critical aortic stenosis, complicated by the transfer from sedation to intubation and stiff arteries due long term dialysis of 20 years.
