| الوصف: | Objective To evaluate the velocity profile of the lateral wall of the left atrium ( LA ) using pulsed‐wave color tissue Doppler imaging ( TDI ) on line and its correlation with two‐dimensional strain rate imaging ( SRI ) by speckle tracking, of equal segments and phases, and other parameters of diastolic function in a population of individuals without known cardiovascular disease. Materials and Methods A total of 91 adults aged 18–74 years, without cardiovascular history, hypertension, diabetes, dyslipidemia or obesity, were evaluated. A Doppler echocardiogram was performed. The lateral wall of the LA was divided subjectively into three portions, the atrial roof was excluded; the peak velocities of the basal and midportions, and their average, were measured with pulsed‐wave TDI on line and SRI . Using both techniques, a first positive wave ( S'la and SRS ‐reservoir phase) and two negative waves ( E'la and SRE —conduit phase—and A'la and SRA —atrial systole—respectively) were obtained. E'la/A'la ratio and SRE / SRA ratio were analyzed. Results The median age was 42 years, and 54.9% of the subjects were female. S'la presented moderate correlation with S' lateral mitral annulus. Both E'la and the E'la/A'la relationships showed moderate to good correlation with various diastolic dysfunction parameters evaluated and SRI. A'la did not present a statistically significant correlation with any of the variables evaluated. Conclusion Evaluation of the lateral wall of the LA by pulsed‐wave color TDI on line is feasible in the vast majority of patients. In the conduit phase, E'la and the E'la/A'la relationship showed correlation with the parameters that evaluate diastolic function and SRI . |
