Abstract

Selective Echo parameters have been used in separating children with VSD with and without pulmonary artery hypertension (PAH). This study was performed to assess specific Echo parameters in pts with endocardial cushion defects (ECD) with and without PAH. 22 pts (2 months - 11 years, 17 females/5 males) were compared with 27 normal controls (C). 5 pts had ASD I°, 3 pts had VSD of the ECD variety and 14 pts had complete A-V canal. Pts were divided into Group I (GI) 4 pts with pulmonary artery systolic pressure (PASP) 50 mm Hg were recognized with no false positive. Thus, these two parameters (early tricuspid closure and increased right isovolumic contraction index) are useful in detecting PAH in children with ECD and could be used to optimize the time of cardiac catheterization.
