【 摘 要 】

Background: Pulmonary hypertension (PH) is a serious problem with high mortality in children, so early diagnosis of this condition is critical. Echocardiography is a non-invasive hemodynamic assessment tool, which facilitates serial follow-ups for hypertensive patients. Objectives: The aim of this study was to evaluate the importance of echocardiographic parameters in children with PH and their correlation with cardiac catheterization parameters. Methods: This cross-sectional study was performed on the records of 20 children with primary PH referred to the pediatric Cardiology Department and clinic of Imam Reza Hospital, Mashhad, Iran, during 2001-2016. The correlation between echocardiography and cardiac catheterization findings was assessed to determine the predictability of echocardiographic parameters in primary pulmonary hypertension. Results: Based on the findings, the mean values of tricuspid regurgitation pressure gradient (TRPG) and peak early diastolic transpulmonary valve pressure gradient (PRPG) were 76.33 ± 22.8 and13.18 ± 44.2 mmHg, respectively. The mean of RA systolic pressure, RA diastolic pressure, RA mean pressure were 13.62 ± 4.43, 5.12 ± 2.1, and 6.77 ± 4.08, respectively. The analysis of data showed a significant correlation between systolic pulmonary artery pressure (PAP) and TRPG (r = 0.62; P = 0.008). We found no significant correlation between systolic PAP and PRPG (r = 0.58; P = 0.03). Additionally, diastolic PAP significantly correlated with TRPG (r = 0.67; P = 0.003) and PRPG (r = 0.64; P = 0.04). Moreover, a significant correlation was observed between mean PAP and TRPG (r = 0.66; P = 0.004) and PRPG (r = 0.64; P = 0.04). Conclusions: Echocardiographic approach is a safe and sensitive method for diagnosis of primary pulmonary hypertension. We found a strong correlation between mean PAP and two variables of TRPG and PRPG.
