Nomogram to Predict Successful Septal Collateral Crossing during Percutaneous Coronary Intervention of Chronic Total Occlusion by retrograde approach: The Sep-CTO score
Abstract:Septal collaterals are the main collaterals used in retrograde chronic total occlusion (CTO) percutaneous coronary intervention (PCI). However, there is little evidence regarding the selection of an interventional septal collateral (SC). we aimed to identify the predictors of successful guidewire crossing using clinical and anatomical characteristics. Overall, 216 derivation cases and 86 validation cases that included retrograde CTO PCI were analyzed. The technical success rate was 79.1% and there were no sign… Show more
