Standart Two Dimensional and Doppler Echocardiographic Data
LV, left atrial (LA), right ventricular (RV) and aortic root (AoR) dimensions and left ventricular wall thickness (LVWT) were measured according to American Society of Echocardiography 2015 guideline of ‘’Recommendations for Cardiac Chamber Quantification by Echocardiography in Adults” 14. The relative wall thickness (RWT) was measured as 2*Posterior Wall Thickness/LV-end diastolic diameter. LV mass was calculated from the parasternal view on the basis of Devereux formula 15.
E and A wave velocities were measured by pulsed wave Doppler (PW) imaging with the 1- 3 mm. sample volume placed at the mitral leaflet tips in three consecutive cycles. Tissue Doppler imaging (TDI) was used to obtain systolic velocity, early and diastolic relaxation velocities at the septal and lateral mitral annulus from the apical 4 chamber view in three consecutive cycles. Left ventricular ejection fraction (LVEF) was calculated using the modified Simpson’s method.
