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

Figure 2

RCA bifurcation CTO PCI: (a) Corsair catheter in the right PLV placed retrograde via septal collaterals from the LAD and antegrade reverse bent wiring with the Crusade catheter failed into PLV; (b) recovery flow of PLV after retrograde balloon dilation; (c) IVUS showed PLV ostium had larger area before PDA stent; (d) angiography of RCA showing TIMI 1 grade flow in the right PLV after stent in the main vessel; (e) retrograde small profile balloon dilation to recovery PLV flow; (f) antegrade balloon and retrograde balloon outside the main branch stent final kissing technique; (g) the final result with flow in the right PDA and PLV; (h) IVUS showed the final PLV ostial area.
