Abnormal left atrial (LA) strain is a potential cause of
LA fibrosis, and the presence of fibrosis will impact LA
strain. We have developed a feature tracking method, and
applied it to 2-chamber cine images of patients to
estimate left atrial strain, and to correlate strain
with late gadolinium enhancement estimations of LA
fibrosis. Preliminary correlation in 9 patients shows a
trend towards lower strain in patients with greater
fibrosis.
