Excimer laser coronary angioplasty in coronary chronic total occlusion: a comparative analysis with OCT navigation
https://doi.org/10.51922/2616-633X.2025.9.2.2604
Abstract
Aim: To compare the safety and efficacy of excimer laser coronary angioplasty (ELCA) versus conventional CTO-PCI under routine OCT guidance and speckle-tracking echocardiography.
Materials and methods: a single-center cohort study included 36 ELCA patients and 22 controls without laser. The endpoints included technical success, OCT parameters (MSA, apposition), changes in GLS and LVEF, and a 12-month MACE.
Results: ELCA yielded a larger stent area, a lower malapposition, and greater improvements in GLS and LVEF with comparable safety.
Conclusion: OCT-guided ELCA improves stent geometry and LV functional recovery compared with non-laser CTO-PCI.
