The retrograde approach for recanalizing chronic total occlusions (CTO) has undergone significant evolution since its introduction in 1990, improving both in terms of techniques and specialized materials. The increased skill applied to this strategy has resulted in increased success rates for the treatment of CTO in sites with an adequate volume of procedures. Given the…
Progress-CTO Score: A Key New Tool to Plan CTO
Intervention of chronic total occlusions (CTO) through angioplasty (PCI) can cause complications, even in highly experienced centers. Plenty has been written on the probability of success for the treatment of CTOs using scores such as CL-SCORE, J-CTO, ORA, E-CTO, CASTLE-CTO, etc. (some of which are usually used when preparing these cases). However, besides estimating success…
