[Tricuspid regurgitation evaluated by Doppler hepatic vein flow patterns]
Journal of Cardiography
|December 1, 1985
Summary
Doppler hepatic vein flow mimics jugular pulses. While not diagnostic for tricuspid regurgitation in atrial fibrillation or post-surgery, it effectively identifies severe cases.
Area of Science:
- Cardiovascular Physiology
- Diagnostic Imaging
- Echocardiography
Context:
- Hepatic vein flow (HVF) is reliably measured using Doppler echocardiography.
- The relationship between HVF patterns and external jugular vein (EJV) pulses was investigated.
- The study assessed Doppler echocardiography's utility in diagnosing tricuspid regurgitation (TR).
Purpose:
- To evaluate the correlation between Doppler hepatic vein flow and external jugular vein pulse.
- To determine the contribution of Doppler echocardiography to the quantitative diagnosis of tricuspid regurgitation.
- To assess HVF patterns in healthy individuals, atrial fibrillation patients, post-cardiac surgery patients, and those with TR.
Summary:
- Doppler hepatic vein flow patterns mirrored jugular phlebograms across all patient groups.
- Normal HVF shows biphasic forward flow and a retrograde atrial contraction wave.
- Abnormalities like systolic backward flow or decreased forward flow were noted in atrial fibrillation and post-surgery patients.
- Severe tricuspid regurgitation correlated with prominent systolic backward HVF, while moderate TR showed decreased systolic forward flow in sinus rhythm.
Impact:
- Doppler HVF measurement is not a reliable diagnostic tool for tricuspid regurgitation in atrial fibrillation or post-cardiac surgery.
- Doppler HVF is valuable for identifying severe tricuspid regurgitation in specific clinical contexts.
- This research refines the application of Doppler echocardiography in cardiovascular diagnostics.
