Tricuspid valve hemodynamics occur approximately 50 milliseconds prior to mitral valve hemodynamics.
True or False
True: Mitral valve dynamics usually occur prior to tricuspid valve dynamics.
The M-mode criteria for tricuspid stenosis includes the following:
B. ) b.) and c.): The M-mode criteria for tricuspid stenosis are similar to the pattern seen in mitral stenosis.
The two-dimensional echo views that allow visualization of at least two tricuspid leaflets include:
E. ) All of the above.
The best two-dimensional echo view for Doppler analysis of the tricuspid valve is the:
B. ) The suprasternal view may also be helpful, but the apical four-chamber view has a more accurate angle to flow.
Which condition is most indicative of tricuspid stenosis?
D. ) Right atrial enlargement is a direct physiological consequence of tricuspid stenosis.
Which tricuspid M-mode criterion clearly indicates tricuspid regurgitation?
D. ) None of the criteria are directly related.
Which of the following two-dimensional echo criteria may be most useful to defining tricuspid regurgitation?
C. ) Right atrial enlargement is a direct physiological consequence of tricuspid regurgitation, as it is of tricuspid stenosis.
The two-dimensional echo view that is best for Doppler analysis of tricuspid regurgitation is the:
D. ) The apical four-chamber view gives the best angle for evaluating tricuspid regurgitation.
Bacterial endocarditis most commonly occurs on the:
B. ) The tricuspid valve is the first valve contacted by returning blood flow to the heart and is therefore the valve where bacterial endorarditis most commonly occurs.
Echocardiographic features of carcinoid heart disease involving the tricuspid valve are:
D. ) and c.): The echo features of carcinoid heart disease in the tricuspid valve are thickened, rigid leaflets that do not close during systole, leaving wide-open tricuspid regurgitation.
When performing a Doppler examination of the inferior vena cava and/or hepatic veins for evidence of tricuspid regurgitation, onw would expect to find:
A. ) and d.) scanning for the inferior vena cava and the hepatic vein is completed in the subcostal position. The presence of flow toward the transducer in systole when flow in the inferior vena cava and/or hepatic vein is being insonated is evidence for tricuspid regurgitation. Normal flow is always away from the transducer in diastole, with or without tricuspid regurgitation.
Tricuspid regurgitation can be recognized on an m-mode
