During minimally invasive cardiac surgery, the 14-gauge livanova needle was inserted into the ascending aorta.When the cardiac surgeon cross-clamped the aorta and the perfusionist attempted to deliver cardioplegia, the cardioplegia flow would not flow more than 100cc's per minute without reaching a high line pressure alarm.The surgeon removed the cross-clamp from the aorta and assessed that the aorta was fine.The surgeon re-cross-clamped and had the same problem of high line pressures with only 100ccs of flow, however the aorta was responding appropriately and there was no evidence of harm to the heart.Therefore, the surgeon decided to continue the surgical procedure.When taking the needle out of the aorta at the end of the case, it was very apparent upon inspection that the needle was deformed.The needle was never clamped down on by an instrument.It looks like it collapsed while in the aorta.
