AB  - CHD including LV volume overload may cause alteration in cardiac functions. Echocardiography could detect systolic and diastolic dysfunction using several echo indices. We performed a comparison between 2 different methods (standard and MPI) in echocardiography to detect cardiac dysfunction in abovementioned diseases. This study was of descriptive and analytic type. We studied 35 patients with left to right shunt such as VSD and PDA and valvular insufficiency such as MR and AI. We consider other 20 healthy people as control group to find normal range of MPI. Echo was performed in case group using standard method (systolic: Cardiac Index, mVCF, LVEF by simpson method and diastolic: E, A, E/A, EF slope), MPI and shunt flow by a pediatric cardiologist. In control group only MPI was measured. The data were analyzed by SPSS 13, descriptive statistic, t test, pearson correlation and chisquare. Thirty five patients at an age limit of 1mo to 9yr and sex of 13 female and 22 male were studied. Non of them had systolic and diastolic dysfunction using echocardiographic standard method. MPI was 0. 27±0. 08 in case group which was slightly higher than 0. 27±0. 06 in control group (NS). MPI had slightly positive correlation to shunt flow , male sex , age andweight which was also nonsignificant. MPI (tei index) is of high value in estimation of systolic and diastolic function. It can be used to diagnose cardiac dysfunction a little earlier than standard method.
