Left ventricular mechanics in idiopathic dilated cardiomyopathy: systolic-diastolic coupling and torsion
J Meluzin, L Spinarova, P Hude, J Krejci… - Journal of the American …, 2009 - Elsevier
BACKGROUND: In idiopathic dilated cardiomyopathy (IDC), myocardial deformational
parameters and their mutual relationships remain incompletely characterized. METHODS:
Thirty-seven patients with IDC underwent two-dimensional speckle-tracking
echocardiography (2D-STE) to assess left ventricular rotation, torsion, and longitudinal,
circumferential, and radial systolic and diastolic strains and strain rates. Additionally, 2D-
STE was performed in 14 controls. RESULTS: All deformational parameters on 2D-STE …
