Left Ventricular Untwist During Isovolumic Relaxation Time in Patients with Diastolic Dysfunction

Document Type : Abstracts

Abstract


The traditional echocardiographic parameters can 
evaluate the left ventricular (LV) diastolic function 
later to mitral valve opening (MVO), while the LV 
untwisting predominantly occurs during the 
isovolumic relaxation interval (IVRT) before MVO, so 
its assessment reflects the LV relaxation. The aim of 
this study was to employ speckle-tracking imaging 
(STI) to examine the LV untwisting during IVRT in 
patients with diastolic dysfunction.
