Abstract

Background: There are limited contemporary data on the dissection strategy with CrossBoss for Chronic Total Occlusion (CTO) Percutaneous Coronary Intervention (PCI). Methods: We analyzed the frequency of use and outcomes of CrossBoss among 2,802 CTO PCIs performed with antegrade dissection and re-entry (ADR) in the PROGRESS-CTO Registry, between 2012 and 2023 at 46 centers. Results: CrossBoss was applied in 539 cases (19.2%), primary CrossBoss in 324 (60.1%), and secondary CrossBoss in 215 cases (39.9%). The knuckle wire strategy was used in 1,563 cases (71.5%), “Scratch and go” in 209 cases (9.6%), and balloon-assisted subintimal entry (BASE) in 165 cases (7.5%). The mean patient age was 65.5 ± 10 years, 85% were men, and 34.8% had prior coronary artery bypass graft surgery. Cases in which CrossBoss was used were less complex with a lower J-CTO score (2.85 ± 1.13 vs 2.96 ± 1.11, P = 0.045). In-stent restenosis was more common in CrossBoss cases (18.9% vs 11.9%, P < 0.001). Technical (84.4% vs 75.6%, P < 0.001) and procedural (82.6% vs 74.0%, P < 0.001) success was higher in the CrossBoss cases and the incidence of major cardiac adverse events (2.97% vs 3.62%, P = 0.457) was similar between CrossBoss and non-CrossBoss cases (Figure 1). Procedure time was similar between the 2 groups (150 [110, 202] min vs 153 [110, 208] min, P = 0.447). Conclusion: CrossBoss is used in 19.2% of ADR CTO PCI cases and is associated with higher technical and procedural success rates and similar major complication rates but less complex lesions compared with ADR cases that did not use CrossBoss.
