The use of 5-4F tapered Expressman GEC for chronic total occlusion. A Angiogram indicated a chronic total occlusion in the left anterior descending coronary artery (LAD). B Angiogram showed the right coronary artery. C and D After antegrade crossing failure, the Sion guidewire was advanced the septal perforating arteries with the support of microcatheter. However, the microcatheter failed to cross the septal branch. The 5-4F tapered GEC was used to increase backup support. E After the Sion guidewire and microcatheter was advanced into LAD, the Fielder XT-R was advanced the CTO lesion. The 5-4F tapered GEC was used for AGT. The final angiogram showed successful deployment of the 2 coronary stents with no visible arterial dissection
