We describe treatment of six chronic total occlusions due to in-stent restenosis with the CrossBoss catheter (BridgePoint Medical, Minneapolis, Minnesota). The CrossBoss catheter allowed successful CTO crossing in 5 of 6 lesions (83%): in 50% the catheter entered the distal true lumen, whereas in 33% a wire was required for distal true lumen crossing. No complications were observed. Use of the CrossBoss catheter can facilitate treatment of coronary chronic total occlusions due to in-stent restenosis.
