-
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:
A.) Dense, thich leaflets.
B.) A reduced A wave.
C.) An increased A wave.
D.) A reduced E slope.
A.) b.) and c.): The M-mode criteria for tricuspid stenosis are similar to the pattern seen in mitral stenosis. (this multiple choice question has been scrambled)
-
The two-dimensional echo views that allow visualization of at least two tricuspid leaflets include:
a.) Parasternal long-axis (right heart).
b.) Parasternal short-axis.
c.) Apical four- chamber.
d.) Apical.
e.) All of the above.
e.) All of the above.
-
The best two-dimensional echo view for Doppler analysis of the tricuspid valve is the:
A.) Suprasternal long-axis view.
B.) Apical four-chamber view.
C.) Parasternal long-axis view.
D.) Parasternal short-axis view.
B.) The suprasternal view may also be helpful, but the apical four-chamber view has a more accurate angle to flow. (this multiple choice question has been scrambled)
-
Which condition is most indicative of tricuspid stenosis?
A.) Right ventricular enlargement.
B.) Right ventricular hypertrophy.
C.) Right atrial enlargement.
D.) Pulmonary insufficiency.
C.) Right atrial enlargement is a direct physiological consequence of tricuspid stenosis. (this multiple choice question has been scrambled)
-
Which tricuspid M-mode criterion clearly indicates tricuspid regurgitation?
a.) Reduced E-F slope.
b.) Mid to late prolapse.
c.) Notching.
d.) None of the above.
d.) None of the criteria are directly related.
-
Which of the following two-dimensional echo criteria may be most useful to defining tricuspid regurgitation?
A.) Right atrial enlargement.
B.) Right ventricular hypertrophy.
C.) Right ventricular enlargement.
D.) Reduced tricuspid E-F slope.
A.) Right atrial enlargement is a direct physiological consequence of tricuspid regurgitation, as it is of tricuspid stenosis. (this multiple choice question has been scrambled)
-
The two-dimensional echo view that is best for Doppler analysis of tricuspid regurgitation is the:
A.) Apical four-chamber view.
B.) Suprasternal long-axis view.
C.) Parasternal short-axis view.
D.) Parasternal long-axis view.
A.) The apical four-chamber view gives the best angle for evaluating tricuspid regurgitation. (this multiple choice question has been scrambled)
-
Bacterial endocarditis most commonly occurs on the:
A.) Mitral valve.
B.) Tricuspid valve.
C.) Aortic valve.
D.) Pulmonic valve.
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. (this multiple choice question has been scrambled)
-
Echocardiographic features of carcinoid heart disease involving the tricuspid valve are:
A.) Tricuspid regurgitation.
B.) Tricuspid prolapse.
C.) Increased pressure half-time.
D.) Thickened, immobile leaflets.
A.) 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. (this multiple choice question has been scrambled)
-
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.) Flow toward the transducer in diastole.
B.) Flow toward the transducer in systole.
C.) Flow away from the transducer in systole.
D.) Flow away from the transducer in diastole.
B.) 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. (this multiple choice question has been scrambled)
