Explanation :

Q.8

65. Which of the following statements about the pathophysiology of Ebstein’s anomaly is/are true?

A. The tricuspid valve is usually insufficient.
B. Typically there is a left-to-right shunt across the ASD.
C. The redundant anterior leaflet of the tricuspid valve may cause obstruction of the right ventricular outflow tract.
D. Pulmonary hypertension is a common late complication.
E. High pulmonary vascular resistance in neonates exacerbates tricuspid regurgitation and cyanosis.

A. A

B. A&C

C. A,C,&E

D. A,B,C,D&E

Explanation :

Q.9

In the surgical treatment of Ebstein’s anomaly, which of the following is/are true?

A. In neonates, the tricuspid valve orifice may be oversewn and a systemic-pulmonary shunt created to provide pulmonary blood flow.
B. Techniques in repair of the tricuspid valve do not utilize plication of the atrialized right ventricle.
C. Closure of the ASD alone is adequate repair of the malformation.
D. If tricuspid valve replacement is performed, the valve should be sutured above the coronary sinus to avoid injury to the conduction system.
E. Currently, mechanical prostheses are recommended for tricuspid valve replacement because the durability of bioprosthetic valves in the tricuspid position is so poor.
