Right ventricular function assessment in healthy people using tissue doppler imaging

Abstract

A growing body of evidence is being gathered regarding the Right Ventricle's (RV) unique function, adaptation, and compensatory role. A widely accessible diagnostic technique, such as echocardiography, should probably enable prompt diagnosis and treatment assessment at the initial stage. The aim of the study was to assess the structural and functional features of the RV in healthy individuals. The study included 185 healthy adults whose ages varied from 16 to 85 years. Everyone who participated in the study had an echocardiographic examination using a standard method and an RV Tissue Doppler Imaging TDI in pulsed mode from the base of the free wall. On the RV TDI, we measured the velocity of the s, e, and waves, and the duration of Isometric Contraction Times (ICT), Ejection Time (ET), and Isometric Relaxation Time (IRT) in milliseconds. In 51% of participants, the e/a ratio was <1. It was detected in 21% of people under 40 years of age and 64% of cases in people over 40. The age of the patients must be taken into account while analyzing the TDI of the RV.
