Right Coronary Artery Total Occlusion and Angioplasty

(A) Bilateral injection showing 2 severe restenotic lesions (middle and distal segments) of the PDA graft and (B) CTO of the proximal RCA. (C) After retrograde wiring using the reverse CART technique, intravascular ultrasound of the RCA was performed, showing diffuse disease with mild parietal calcium and negative remodeling. (D) The final result after implanting 3 drug-eluting stents (distal, middle, and proximal segments). CART = combined antegrade and retrograde subintimal tracking; CTO = chronic total occlusion; PDA = posterior descending artery; RCA = right coronary artery; SVG = saphenous vein graft.
