Excimer laser atherectomy in an uncrossable long chronic total occlusion through the subintimal space

2020

We present a successfully chronic total occlusions (CTO) coronary recanalisation with the subadventitial space by excimer laser atherectomy (ELCA) adjunctive therapy. Angiogram revealed non-significant diffuse disease of the left coronary system with a complex long proximal right coronary artery (RCA) CTO (J-CTO score 4) and collaterals (Rentrop Grade 2 and Werner classification CC1) from the septal branches (Figure 1, Panel A). CTO PCI of the RCA was then indicated and planned. Initially, antegrade approach and a retrograde approach technique were attempted without success. Thereafter, a rescue Antegrade Dissection Reentry strategy (ADR) was applied. A Pilot 200 (Abbott) was advanced in a …
