Comparisons of traditional diastolic echocardiographic parameters among three groups of paediatric cardiomyopathies and healthy controls. Mean and standard deviation of diastolic parameters in the study population by cardiomyopathy type. (A) E/A: mitral inflow peak E-to-A wave velocities ratio. (B) DT: mitral E wave deceleration time. (C) E/E’ avg: mitral inflow peak E-to-mean septal and lateral tissue velocities E’ ratio. (D) LAVi: left atrial volume indexed to body surface area. (E) PTRG: peak tricuspid regurgitation gradient. (F) LS: left ventricular longitudinal strain. * p < 0.01 compared to CTRL. # p < 0.01 compared to HCM. § = p < 0.01 compared to DCM. CTRL: normal controls. HCM: Hypertrophic Cardiomyopathy. DCM: Dilated Cardiomyopathy. RCM: Restrictive Cardiomyopathy.
