Question

One advantage to using the parasternal long axis view to diagnosis mitral valve prolapse is:

a) there is less motion of the mitral annulus
b) false prolapse caused by the annulus shape is avoided
c) the ultrasonic beam if perpendicular to the leaflets in systole
d) the relative position of the mitral and tricuspid valves is better visualized

Answer 1

The advantage of using the parasternal long axis view in diagnosing mitral valve prolapse is that the ultrasonic beam is perpendicular to the leaflets during systole, aiding in an accurate diagnosis.

Step-by-step explanation:

One advantage to using the parasternal long axis view to diagnose mitral valve prolapse is that the ultrasonic beam is perpendicular to the leaflets in systole. This perpendicular alignment allows for a more accurate assessment of the valve's movement and can help in determining if there is a prolapse. The chordae tendineae are critical for the functioning of the mitral valve; if they are damaged or broken, it can lead to valve failure, causing blood regurgitation and a heart murmur as the normal one-way blood flow is disrupted.
