Can Cardiovascular Magnetic Resonance myocardial feature tracking (CMR-FT) reliably quantify left atrial strain and strain rate to discriminate between patients with impaired left ventricular relaxation and healthy controls?
CMR-FT is a feasible and promising novel approach for quantifying left atrial deformation from standard cine images to study atrial performance.
CMR-FT based atrial performance analysis reliably quantifies LA longitudinal strain and SR from standard SSFP cine images and discriminates between patients with impaired left ventricular relaxation and healthy controls. CMR-FT derived atrial deformation quantification seems a promising novel approach for the study of atrial performance and physiology in health and disease states.
Kowallick et al. (Mon,) studied this question.
