Right ventricular systolic function assessment methods and its correlation for determining the RV function in patients with structurally normal heart and normal pulmonary artery pressure

Abstract

Background: In clinical practice, RV assessment is often based on qualitative estimation, and it is regarded as a neglected chamber. The right ventricle (RV) has a critical function in cardiovascular physiology and pathology. It is currently receiving increasing attention for its recognition as a critical component of many cardiovascular conditions.

Objectives: To determine the most appropriate method for RV Function assessment in patients with structurally normal heart and normal pulmonary artery pressure by echocardiography.

Methods: Echocardiographic imaging was performed using the VIVID E7  echocardiographic system  (GE)  with a  standard transducer, and electrocardiogram-gated images with a  minimum of  5  cardiac loop images were acquired.  Echocardiographic data will be stored on a  personal computer with dedicated software for offline analysis.

Results: In the present study, the Right ventricular parameters were measured using M-mode and doppler echocardiography. The right ventricular Systolic parameters like S’ had no significant difference with that of RVMPI (P value = > 0.05). Moreover, there was significant difference between the right ventricular Systolic parameters like S’ with that of TAPSE, FAC (P value = < 0.05).

Conclusion: In our study, we assessed the right ventricular function by comparing the RV systolic velocity with RVMPI, TAPSE and FAC. We found a good correlation between TAPSE, FAC, and RV systolic velocity. But RVMPI did not correlate with RV Systolic velocity.
