Determining the Role of Tissue Doppler, Strain and 3D Echocardiographic Parameters in Pulmonary Hypertension | Chapter 16 | New Horizons in Medicine and Medical Research Vol. 3

 Introduction: A variety of echocardiographic parameters are used to investigate right ventricular (RV) function, which has a prognostic impact on pulmonary hypertension (PH). Other cardiac imaging techniques, such as cardiac magnetic resonance imaging, are likewise more expensive for serial testing and less widely available than echocardiography (MRI).

Our goal was to see how well known prognostic markers correlated with standard and advanced echocardiographic parameters like Tissue Doppler Imaging (TDI), strain imaging, and three-dimensional (3D) echocardiography.

Methods: The following variables (among others) were examined in 51 patients with PH: Right Atrial Area/Volume and Global Longitudinal Strain (GLS), Tricuspid Annular Plane Systolic Excursion (TAPSE), RV Fractional Area Change, RV GLS, RV Tei Index, Pulmonary Artery Systolic Pressure (PASP), Pulmonary Acceleration Time (PAcT), Tricuspid s' RV end-systolic (ES), end-diastolic (ED) volumes (V), and ejection fraction (EF) were calculated in 42 patients (EF). Clinical and demographic information, as well as data on the six-minute walk test (6MWT) and brain natriuretic peptide (BNP), were gathered.

Results: There was a statistically significant (p 0.05) association between 6MWT and RV Tei Index (r = -0.336), PASP (r = -0.388), PAcT (r = 0.661), RVESV (r = -0.380), RVEF (r = 0.381), as well as BNP and TAPSE (r = -0.332),ytu5 Tricuspid s' (r = -0.29), PAcT (r

Conclusions: In this PH population, traditional echocardiographic parameters, which have several limitations, as well as advanced parameters obtained by 3D echocardiography, particularly RV GLS and EDV/EF, showed a significant correlation with well-studied prognostic markers, reinforcing the need for a more comprehensive study of RV function.
