Right ventricular outflow tract velocity time integral (RVOT VTI) and tricuspid regurgitation velocity/RVOT VTI ratio in pediatric pulmonary hypertension
Doppler echocardiography is a simple method of assessing hemodynamics in patients with pulmonary hypertension (PH). Determination of the right ventricular outflow tract velocity time integral (RVOT VTI) is a part of the non-invasive investigation of pulmonary flow in adults [1,2]. The normal range of RVOT VTI in adults is stable, and differences serve as indicators for changes in RV stroke volume. In children, non-invasive techniques to assess pulmonary blood flow are of interest because such investigations do not require invasive cardiac catheterization (CC) that is not without risk in PH children [3].
