Popis: Introduction: Left ventricular (LV) diastolic dysfunction is common on preoperative screening among patients undergoing surgery. There is no simple screening test at present to suspect LV diastolic dysfunction. This study was aimed to test the hypothesis, whether elastic recoil signal (ERS) on tissue Doppler imaging of mitral annulus (MA TDI) can be used as a qualitative test to differentiate patients from normal LV diastolic function versus patients with LV diastolic dysfunction. Methods: This was a prospective cross-sectional observational study of patients admitted for elective surgeries. Normal diastolic function and categorization of LV diastolic dysfunction into severity grades I, II, or III were performed as per the American Society of Echocardiography/ European Associationof Cardio Vascular Imaging (ASE/EACVI) recommendations for LV diastolic dysfunction. Results: There were 41 (61%) patients with normal LV diastolic function and 26 (39%) patients with various grades of LV diastolic dysfunction. In 38 out of 41 patients with normal LV diastolic function, the characteristic ERS was identified. The ERS was absent in all the patients with any grade of LV diastolic dysfunction. Consistency of identification of ERS on echocardiography was tested with a good interobserver variability coefficient of 0.94 (P-value
