Representation of the Reverse CART Technique
(A) Two guidewires are positioned and overlapped inside the CTO. (B) A balloon is advanced over the anterograde guidewire and inflated after crossing the proximal cap. (C) After balloon inflation, a new pathway is formed that allows retrograde progression of the distal guidewire. CART = combined antegrade and retrograde subintimal tracking; CTO = chronic total occlusion.
