This study investigated the benefits of percutaneous coronary intervention (PCI) in patients with chronic total occlusions (CTOs) by using cardiac magnetic resonance imaging (CMR)-feature tracking (CMR-FT).The results showed the infarct size and LVEF did not increase significantly from baseline to 1 year of follow-up.However, global peak strains improved over time, and GCS showed significant treatment effect of CTO-PCI in the entire CMR population,which indicated improvement in left ventricular function.
