Non invasive assessment of right ventricular function in patients with congenital heart disease using Doppler tissue imaging and Tei-index

ABSTRACT

We assessed the clinical utility of using myocardial performance index [Tei index] and tissue Doppler imaging as noninvasive indices of right ventricular function in patients with congenital heart disease. Tei ilidex and trans annular [tricuspid] flow were performed in 100 subjects, 30 were completely healthy represented as control group and 70 had variable congenital heart disease, this group is subdivided according to the loading condition on the right ventricle into two subgroups volume loaded and pressure loaded right ventricle. In patients with volume, loaded right ventricle both Tei index and trans annular parameters did not differ significantly when compared to control group but they differ significantly in patients who have complex heart disease and pressure loaded right ventricle. Patients with Transposition of the great vessels and those with pulmonary hypertension had reversed Ea/Aa values. So Doppler tissue imaging and Tei index are valuable noninvasive tools for assessment of right ventricular function
