Answer to Question 1

ANS: A
In mitral valve prolapse (MVP), a portion of the mitral valve flops open up into the left atrium, giving rise to a classic mid-systolic click followed by a soft grade I murmur that crescendos up to S2. It is high pitched and is heard best at the apex or left sternal border.

Answer to Question 2

ANS: B
Echocardiography is the best diagnostic test for assessing a heart murmur. In addition to visualizing the diseased valve, echocardiography can assist in determining the size of the heart chambers involved in the heart murmur in real time.
