Abstract
Tricuspid Regurgitation is backflow of blood from the right ventricle to the right atrium due to imperfections in the tricuspid valve or it could also be when the tricuspid heart valve does not close tightly (leaks). The aim of the study was to determine the Severity level of Triscuspid Reguritas in Congestive Heart Failure (CHF) patients. This research method is descriptive research with a case study approach, because its implementation includes data, analysis and interpretation of the data obtained. In this research, three methods were used, namely Vena Contracta, Color flow imaging, and CW Doppler. The research results obtained were, when examining patient 1 using the CW Doppler method, looking at the TR Doppler, the Doppler was dense, parabolic and triangular, which means the TR was moderate, the Vena Contracta method in patient 1 showed mild TR because when the measurement was carried out in the color jet the narrowest is at the tricuspid valve, the value obtained is 0.25cm which means <0.3cm. In patient 2, using the Color flow imaging method, mild tricuspid regurgitation was obtained, called mild because the shape of the central jet is small and thin, which indicates mild TR, the CW Doppler method in patient 2 obtained a Doppler signal that was below the baseline and had a parabolic shape, which means TR mild. For CW Doppler with pulmonary artery pressure the results were 2.45m/s.
