The use of 5-4F tapered Expressman GEC for severely calcified lesion. A Angiography indicated a subtotal occlusion in the right coronary artery (arrow). B X-ray showed calcified lesion with angulation. C With the support of 5F Guidezilla GEC, the lesion was dilated using a 2.0 mm and 2.5 mm balloon. However, the Resolute stent (3.0 × 22 mm) failed to cross the lesion. The 5F GEC was hampered at position of calcified lesion. D The 5-4F tapered GEC was advanced beyond the lesion with an anchor balloon technique. The stent was delivered beyond the target lesion via GEC. The arrow indicates the tip of the GEC. E The Resolute stents (3.0 × 22 mm and 3.5 × 22 mm) were positioned and deployed in the target lesion. F The final angiogram showed successful deployment of the 2 coronary stents with no visible arterial dissection
