OBJECTIVE The aim of the study is to determine the usefulness of Tei index, an echocardiographic parameter, in early prediction of the pulmonary artery pressure in congenital heart diseases with left-to-right shunt.
METHODS Right and left ventricular functions were evaluated with Tei index which were determined with tissue Doppler echocardiography. The cardiac catheterization was performed for all patients. The patients with mean pulmonary artery pressure ≥25 mmHg and pulmonary vascular resistance index >3 WU/m2 were considered as pulmonary arterial hypertension. Also, the patients with pulmonary/systemic blood flow ratio ≥2 were considered eligible for surgery.
RESULTS The values of Tei index measured from the left ventricular posterior wall and the right ventricle anterior wall were found to be significantly higher in the patients with pulmonary arterial hypertension (0.68±0.18, 0.67±0.16) compared with the patients without pulmonary arterial hypertension (0.56±0.16, 0.51±0.12), (p=0.027, p=0.001). Also, a significant correlation was detected between Tei index measured from the left ventricular posterior wall and mean pulmonary artery pressure (correlation coefficient: 0.491).
CONCLUSION The values of right ventricular Tei index in children with congenital heart disease with left-to-right shunt can be used as a parameter to follow up the development of pulmonary arterial hypertension, to diagnose it in the early period and to decide surgery on time.
