Changes in strain parameters at different deterioration levels of left ventricular function: A cardiac magnetic resonance feature-tracking study of patients with left ventricular noncompaction

BackgroundThere is a lack of cardiac MRI information on left ventricular (LV) strain and rotational parameters noncompaction (LVNC) patients with reduced ejection fraction (EF). Thus, we sought to use feature tracking (FT) describe these changes at different levels EF deterioration.MethodsWe included 31 adult LVNC LV (Group B, < 50%) without any comorbidities or concomitant diseases, age- sex-matched good A, > healthy controls. Group B was divided according into two subgroups B-1: 35–50%, B-2: 35%). Their global longitudinal, circumferential (GCS), radial (GRS) strains; segmental apical basal rotation values; patterns degree dyssynchrony were measured.ResultsAll the mean significantly worse in Groups B-1 B-2 than A The mechanical dispersion increased as decreased. highest control group, almost same lowest reverse direction B-2. pattern, clockwise-directed rigid body (RBR), found 39% patients, counterclockwise-directed RBR 26% patients.ConclusionsThe values changed These affected LV, did not identify an LVNC-specific pattern.
