Figure 1. Coronary angiogram with bilateral injection (A & B) and pre-procedural curved multiplanar reformation image (C). White arrows demonstrate CTO of the LAD with severe calcification. When the guidewire reached the distal lesion of the CTO, just before the distal true lumen (D), an intraprocedural CCTA was performed on site without contrast injection (E). Matching cross-sectional CCTA images showed the location of the guidewire in the coronary artery including CTO segments (F-J). Cross-sectional CCTA images at the wire tip level clearly showed the guidewire inside the intimal plaque of the CTO (H & I). The asterisks and blue ...
