A high sweep speed ensures greater details of the waveform.ĭiagnosis is made when the regurgitation jet velocity is at least 80 cm/sec and its interval extends to more than half of systole 7.Color Doppler shows flow in the opposite direction with a different color compared to mitral valve flow with aliasing, denoting high-velocity flow in opposite direction. It is recommended that the sweep speed is set at 200-300 mm/sec. Technique: the pulsed Doppler gate (sample volume of 2-3 mm) should be placed perpendicular across the tricuspid valve in the four-chamber view with the angle of insonation <20°. Radiographic features Antenatal ultrasound
Trivial tricuspid regurgitation can be an isolated finding in an otherwise normal fetus with no other structural abnormality 2. It may be associated with aneuploidy and with both cardiac and extracardiac defects 3-5. Tricuspid regurgitation is a common sonographic finding during fetal life and can be seen in 7% of normal fetuses 1.
