Retrograde Balloon Dilation outside the Main Branch Stent to Restore the Occlusion of Side Branch in Chronic Total Occlusion Bifurcation Lesions

Figure 1

Recanalization of RCA CTO by a retrograde approach. (a) CAG showed LAD to RCA collaterals. (b) Simultaneous bilateral CAG showed long RCA CTO at bifurcation with large branches; (c) Corsair catheter in the right PDA placed retrograde via a epicardial collateral from the LAD, and tip injection showed antegrade wire in false lumen; (d) retrograde wire and Corsair into antegrade Guidezilla guide; (e) sequentially predilation RCA along antegrade RG3 wire; (f) retrograde angiography showed the severe disease in PLV.
