Longitudinal strain in left ventricular non-compaction: insights derived from two-dimensional speckle-tracking echocardiography and cardiac magnetic resonance imaging strain

Patients with CMR-confirmed LVNC demonstrated reduced global LS and a consistent pattern of more pronounced apical strain impairment. STE and CMR showed reasonable concordance in mid-apical regions, supporting the complementary role of deformation imaging in the evaluation of LVNC. Incorporating LS into routine assessment may improve detection of functional impairment. Further studies are needed to determine the optimal strain-based approach and clarify its relationship with underlying anatomical abnormalities.
