Physician had a jr2 catheter (containing coronary wire and protrack microcathether) positioned under the atretic pulmonary valve; when the coronary wire was exchanged for nykanen.The nykanen wire was straightening out their jr2 catheter, and they no longer had a good positioning under the valve.Physician opted for stiff back end of guidewire and mechanically crossed through the valve because they could not get good positioning when using the nykanen wire.While there was no adverse event related to the use of the baylis medical device, baylis medical technologies considers a device malfunction leading to a surgical delay of greater than 15 minutes to be an fda reportable event.
