Adult Echocardiography Practice Exam

What possible coexisting defect is often seen with a bicuspid aortic valve?

1. A. cleft mitral valve

2. B. parachute mitral valve

3. C. coarctation of the aorta

4. D. cleft tricuspid valve

The correct answer is: C. coarctation of the aorta

A bicuspid aortic valve is a congenital heart defect that features only two cusps instead of the normal three. This condition is often associated with other congenital anomalies, and one of the most common coexisting defects is coarctation of the aorta. Coarctation of the aorta is a narrowing of the aorta, usually occurring just distal to the left subclavian artery. This association is thought to be related to the developmental processes of the heart and great vessels during embryogenesis. The presence of a bicuspid aortic valve can influence the hemodynamic forces and flow patterns in the aorta, leading to changes that may predispose a person to coarctation. In summary, the link between bicuspid aortic valve and coarctation of the aorta highlights the importance of considering both conditions in patients presenting with either defect, as intervention may be necessary for optimal management of associated complications.
