TCT-98 Calcium Modification Strategies in Dissection and Re-Entry Versus Wiring Techniques in Chronic Total Occlusion Percutaneous Coronary Intervention

摘要: BackgroundThe use of calcium modification strategies in dissection and re-entry compared with wiring techniques in chronic total occlusion (CTO) percutaneous coronary intervention (PCI) has received limited study.MethodsWe analyzed the procedural outcomes of 1,241 CTO PCIs that required the use of 1 or more calcium modification strategies at 42 centers from 2012 to 2023.ResultsA calcium modification strategy was used as part of a dissection and re-entry strategy in 23% and as part of wiring technique in 77%. The most common calcium modification strategy in the dissection and re-entry group was scoring balloon (29.5%) and rotational atherectomy (29.5%), followed by laser atherectomy (20.7%) and intravascular lithotripsy (IVL)(18.3%). In the wiring group, rotational atherectomy (38.3%) was the most frequently used calcium modification therapy, followed by laser atherectomy (25.8%), IVL (17.8%), and …
