<abstract xmlns="http://www.w3.org/1999/xhtml">Background and Aims. Two-dimensional (2D) and Doppler echocardiography are the main methods for the non-invasive evaluation of ventricular function in children. Our study monitored the evaluation of systolic and diastolic function in pediatric patients, using classical echocardiographic parameters and pulsed tissue Doppler parameters, as well as the correlation between these. Methods. The study included 18 healthy children and 9 children diagnosed with congestive heart failure secondary to congenital heart malformations. The parameters of systolic and diastolic function were measured by 2D echocardiography, 2D guided M mode, color and pulsed Doppler, as well as by pulsed tissue Doppler at the level of the mitral and tricuspid annulus. Results. A relaxation alteration pattern or a pseudonormal pattern of E diastolic velocity compared to the A wave was found (E = A; E > A) in the group of subjects with heart failure. E wave deceleration time had significantly increased values in the case of patients with CHF, being correlated with diastolic dysfunction. Left ventricular flow propagation velocity Vp was decreased in patients with heart failure, the E/Vp ratio being maintained relatively constant in subjects with congestive heart failure and healthy subjects, most probably on account of the concomitant change in the E wave. Associations between the severity of systolic dysfunction and the diastolic dysfunction were found in pediatric patients diagnosed with congestive heart failure (Student test, p &lt; 0.05). Conclusions. Tissue Doppler measurements proved to be useful for the evaluation of pediatric patients with altered ventricular geometry secondary to congenital heart disease, systolic-diastolic dysfunction and heart failure.</abstract>
