Left Ventricular Torsion by Two-Dimensional Speckle Tracking Echocardiography in Patients with Diastolic Dysfunction and Normal Ejection Fraction

Systolic torsion and diastolic untwisting are significantly increased in patients with mild diastolic dysfunction. In patients with advanced diastolic dysfunction with increased filling pressure, they are normalized or reduced. Whether increased LVtor is a compensatory mechanism for reduced myocardial relaxation or a consequence of reduced filling in the early stage of diastolic dysfunction requires further investigation. Analysis of LVtor with speckle tracking echocardiography should be further explored to elucidate the role of torsion in patients with diastolic dysfunction.
