Figure 1. Intravascular lithotripsy in chronic total occlusion (CTO) percutaneous coronary intervention (PCI). A) Calcified ostial right coronary artery (RCA) CTO with recoiled stent (arrow) and (B) septal collaterals. C) Retrograde approach via septals and CTO crossing into the aorta. D) Incomplete expansion of 3.5 mm non-compliant (NC; left) and scoring (right) balloons. E) Intravascular lithotripsy (3.5 mm Shockwave; left), followed by balloon dilatation (4.0 mm NC; right), achieves better lesion preparation. F) Final result after implantation of two stents. G) Calcified mid RCA CTO with (H) septal collaterals. I) Rotational atherectomy (1.5 mm burr) on the proximal segment (top) and CTO (bottom). ...
