Abstract:
Objective: To compare the efficiency of two-dimensional speckle tracking echocardiography (2D-STE) and late gadolinium enhancement (LGE) cardiac magnetic resonance (CMR) for detecting cardiac amyloidosis. Methods: Systolic longitudinal peak strain by 2D-STE and LGE by CMR were retrospectively analyzed in 10 patients with cardiac amyloidosis. Results: CMR showed 10 patients with LGE and 2D-STE showed 9 patients with ventricular systolic longitudinal peak strain decreasing, the diagnostic consistency of CMR and 2D-STE was 90％. There were 4 patients having both strain abnormality and LGE at meanwhile, 4 patients without CMR presented right ventricular involvement while with 2D-STE indicated abnormal right ventricular systolic longitudinal peak strain, 1 patient with CMR presented LGE in ventricular sepatum while 2D-STE indicated systolic longitudinal peak strain decreasing in both ventricles. Conclusion: 2D-STE and CMR had good consistency for diagnosing left ventricular involvement in patients with cardiac amyloidosis; 2D-STE may have better sensitivity for diagnosing right ventricular amyloidosis.
