Objective. The objective of this study was to determine the frequency of pulmonary arterial hypertension PAH in congenital heart disease CHD with an isolated, large left-to-right shunt and to indicate the factors in the development of PAH. Methods. The pressure measurements in the cardiac chambers and the calculations based on the Fick’s principle were compared among 3 separate groups of patients, respectively, with PAH, with hyperkinetic pulmonary hypertension HPH, and with neither PAH nor HPH. Results. PAH was diagnosed in 30 12.3% patients, HPH in 35 14.4%, while 177 73.1% were free of either. The highest risk for the development of PAH was found in the presence of perimembranous ventricular septal defect. A statistically significant difference was seen among these groups as to their left atrial pressure and the mean pulmonary arterial pressure PAPmean; . While a correlation was present between RpI on one hand and age on the other , a multiple linear regression could not evidence any correlation among age , gender . Conclusion. Our findings do not allow establishing a correlation between the duration of the high pulmonary flow and pulmonary vascular resistance increase or PAH development in isolated left-to-right shunts with congenital heart diseases.
