For patients undergoing RTCA with significant brachiocephalic/thoracic aorta tortuosity, "elephant head," a Tiger catheter can be used efficiently for curvatures <1 cm from the middle of the spine. We propose that for curvatures >1 cm, operators should consider immediately switching to a JL catheter.
