LGALS3 and cardiac arrhythmia: Galectin-3, as a marker of ventricular function, was also assessed in a cohort of adults with a systemic right ventricle by Geenen et al. [43] and only weak correlations were found in relation to right ventricle global longitudinal strain; however, again, higher galectin-3 levels were associated with an increased risk of arrhythmias.
