CHAPTER 12: TRICUSPID AND PULMONIC VALVES
++
++
++
++
1. Tricuspid regurgitation can occur:
+
+
++
a. In the absence of other valvular diseases
+
++
b. In association with mitral valve prolapse
+
++
c. Secondary to pulmonary hypertension
+
++
d. With a structurally normal tricuspid valve
+
++
+
++
++
++
++
2. Which of the following statements about the tricuspid valve is false?
+
+
++
a. Mild tricuspid regurgitation on transesophageal echocardiography is a common finding in normal, healthy individuals.
+
++
b. Systolic pulmonary artery pressure can be estimated by measuring the tricuspid regurgitation jet velocity.
+
++
c. In a patient with pulmonic stenosis, estimation of the right ventricular systolic pressure can be obtained from Doppler interrogation of the tricuspid regurgitant jet.
+
++
d. In a patient with tricuspid regurgitation, color Doppler interrogation of the regurgitant jet is always enough to determine its severity.
+
++
++
++
++
3. The three leaflets of the tricuspid valve can be assessed in which of the following tomographic views?
+
+
++
a. Midesophageal RV inflow-outflow view
+
++
b. Midesophageal four-chamber view
+
++
c. Transgastric RV inflow view
+
++
d. Transgastric RV basal view
+
++
++
++
++
4. Which of the following does not indicate the presence of severe tricuspid regurgitation?
+
+
++
a. Systolic reversal of the coronary sinus flow
+
++
b. Presence of noncoaptation of the tricuspid leaflets
+
++
c. Dense CW Doppler signal of the tricuspid regurgitation jet
+
++
d. Systolic dominance of hepatic vein flow
+
++
++
++
++
5. Estimation of the systolic pulmonary artery pressure is best done in which of the following views?
+
+
++
a. Midesophageal two-chamber view
+
++
b. Midesophageal four-chamber view
+
++
c. Transgastric RV inflow view
+
++
d. Transgastric short-axis view
+
++
++
++
++
6. Assessment of pulmonic insufficiency using color flow Doppler can be performed in all of the following tomographic views except?
+
+
++
a. Midesophageal RV inflow-outflow view
+
++
