Cardiac magnetic resonance in recovering COVID-19 patients. Feature tracking and mapping analysis to detect persistent myocardial involvement

•Post-COVID-19 patients may incur myocardial involvement secondary to systemic inflammation. Compared to heathy controls, post-COVID-19 patients had raised T2 mapping values, but similar native T1, Feature Tracking-Circunferencial Strain and Feature Tracking-Radial Strain values. When study group patients were sub-grouped according to contact-to-CMR interval (<8 weeks and ≥8 weeks), we found lower FT-CS and FT-RS values for the shorter interval.
