Question 3

What is the correct explanation for how cardiac tamponade can affect the heart?

Accepted Answer

A)  It causes a prolapsed mitral valve, one whose flaps extend back into the left atrium, causing incompetence (leaking) of the valve. 
B)  It causes blood to not only eject forward into the aorta but also regurgitate back into the left ventricle because of a leaky aortic semilunar valve. 
C)  It is a compression of the heart that impairs its pumping action and makes immediate pericardial drainage necessary. 
D)  It is a delayed inflammatory response to streptococcal infection that results in stenosis or other deformities of the valves, chordae tendineae, or myocardium.
