Exit of CrossBoss between stent struts within chronic total occlusion to subintimal space: Completion of case via retrograde approach with rendezvous in coronary

Abstract We present a case of successful percutaneous revascularization of a chronic total coronary occlusion due to in-stent restenosis. The CrossBoss catheter (BridgePoint Medical, Minneapolis, MN, USA) was used initially because it is reported to be effective in this setting with a low risk of ex...

Description
Summary:Abstract We present a case of successful percutaneous revascularization of a chronic total coronary occlusion due to in-stent restenosis. The CrossBoss catheter (BridgePoint Medical, Minneapolis, MN, USA) was used initially because it is reported to be effective in this setting with a low risk of exiting occluded stents. To the best of our knowledge, this is the first reported case of a CrossBoss penetrating through stent struts into the subintimal space. The case was completed via the retrograde approach with ‘rendezvous in coronary’. < Learning objective: Recognize the potential of the CrossBoss catheter to exit between stent struts within chronic total occlusions. Appreciate the need to check the position of the CrossBoss catheter with respect to stents within a chronic total occlusion. Identify the potential for ‘rendezvous in coronary’ within the subintimal space with the CrossBoss catheter and a retrograde guidewire.>
