Abstract
The retrograde approach via native channels, mainly septal collaterals, has now become routine. However even after retrograde advancement of a catheter through a collateral channel, it is sometimes difficult to guide the catheter from a false lumen into the true lumen. We experienced 3 patients in whom the site for retrograde guidewire re-entry site from the chronic total occlusion was unclear, and intravascular ultrasound (IVUS) was useful for identifying the re-entry site. Here we report on this new technique, in which IVUS guides the retrograde guidewire to its re-entry site.
