Optimal use of fielder XT guidewire enhances the success rate of chronic total occlusion percutaneous coronary intervention

Figure 1 An illustrative image of the Fielder XT guidewire.

Figure 2 Fielder XT guidewires enter the chronic total occlusion lesions along the microchannels with different anatomical features. A: Microchannels partly or completely connecting from the proximal cap to the distal end of chronic total occlusion (CTO) lesion; B: A Fielder XT guidewire crossing the CTO lesion through microchannels; C: A Fielder XT guidewire entering the sidewall of the coronary artery and resulting in forming intimal dissection; D: A Fielder XT guidewire entering the side branch of the occlusion segment; E-F: After leaving the Fielder XT guidewire in the false lumen, tracing of a second tapered guidewire along the same pathway into the true lumen; G: A Fielder XT guidewire crossing the occlusion segment into the subintimal of the distal cap; H: A stiff guidewire with a tapered tip entering the distal true lumen after the distal cap.
