B)
"This could be caused by an infection. Have you been feeling well the past few weeks?"
C)
"One of your heart valves is not opening properly. We need to do an echocardiogram to see which valve is having problem."
D)
"This may make you a little more fatigued than usual. Let me know if you start getting dizzy or light-headed."
Ans:
C
Feedback:
Stenosis refers to a narrowing of the valve orifice and failure of the valve leaflets to open normally. Blood flow through a normal valve can increase by five to seven times the resting volume. Valvular disease is not caused by stress. The murmur can be caused not only by infection but also by stenosis or regurgitation of a valve leaflet. The valve problem is very severe if it is causing signs of decreased cardiac output.
