Abstract
Background: The tip-detection method and the retrograde approach have been acknowledged as a second-line strategies for chronic total occlusion (CTO) percutaneous coronary intervention (PCI) when conventional antegrade wiring strategies are ineffective. The aim of this study is to compare the efficacy between both strategies for complex CTO PCI.
Methods: We retrospectively enrolled 170 consecutive CTO PCI cases and separated them into 295 adopted strategies. The rate of successful lesion crossing and its association with the time spent for each strategy were compared between the tip-detection method and the retrograde approach.
Results: We observed fifty-six attempts with the tip-detection methods with 46 (82.1%) successful lesion crossings. Sixty-one retrograde approaches were performed, in which 29 (47.5%) cases achieved procedural success. In the successful attempts, the wire-manipulation time was significantly shorter in the tip-detection method [20.0 (12.2-36.7) min] than the retrograde approach [35.0 (20.7-49.7) min] (p = 0.008). Cox-regression analysis showed time-dependent advantage for the tip-detection method over the retrograde approach [hazard ratio (HR) = 2.93, 95% CI = 1.84-4.67, p < 0.001]. Incomplete tip-detection CTO crossing (taking > 30 min) was seen in severely tortuous lesions [odds ratio 0.26, 95% confidence interval 0.06-0.97, p = 0.037].
Conclusion: The tip-detection method can reduce the wire-manipulation time for successful CTO PCI compared with the retrograde approach. However, the success rate of the tip-detection method is hampered by severe lesion tortuosity.
