Select the best answer.

1. Tricuspid regurgitation can occur:

b. In association with mitral valve prolapse

c. Secondary to pulmonary hypertension

d. With a structurally normal tricuspid valve

e. With all of the above

e.

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.
