Optical Coherence Tomography to Better Assess Chronic Total Occlusion Percutaneous Intervention Results

Résumé fourni par la source

BACKGROUND: Angioplasty of coronary chronic total occlusions (CTOs) was a breakthrough, but there is a lack of data concerning stent healing after these complex procedures. OBJECTIVES: The main aim of the PERFECTO (Post-stEnting assessment of Reendothelialization with optical Frequency domain imaging aftEr CTO procedure) study is to assess, for the first time, stent strut apposition at the index CTO procedure and at 3-month follow-up using frequency-domain optical coherence tomography (FD-OCT). METHODS: From March 2018 to January 2020, 114 consecutive patients who underwent successful CTO recanalization >20 mm in length were prospectively included in 7 centers. FD-OCT was performed for ad hoc guidance during the index procedure and at 3-month follow-up. All patients received the same last-generation drug-eluting stent. RESULTS: at 3 months, P < 0.0001). No complication occurred with FD-OCT. CONCLUSIONS: CTO-percutaneous coronary intervention could affect stent healing with a high incidence of immediate and late-acquired malapposition. These results support the interest of using FD-OCT during follow-up to better assess CTO recanalization results.
