You have been called upon to demonstrate the technique for listening to valve sounds. a. Explain where you would position your stethoscope to auscultate (1) the aortic valve of a patient with severe aortic valve insufficiency and (2) a stenotic mitral valve. b. During which period(s) would you hear these abnormal valve sounds most clearly? (During atrial diastole, ventricular systole, ventricular diastole, or atrial systole?) c. What cues would you use to differentiate between an insufficient and a stenotic valve?

Video transcript

Welcome back, everyone. Our next problem says aortic stenosis develops when the aortic valve narrows and blood flow becomes restricted. Identify the heart sound that the doctor may hear with a stethoscope in a person with aortic valve, stenosis. A love B dup C murmur or D, both A and B. Well, the sound you'd expect to hear with this narrowing of the aortic valve is choice C A murmur. The narrowing means that the blood doesn't flow through as easily as it would otherwise. So you have this sort of high pitched sound caused by that restricted flow. When we look at our other answer, choices, love and death are normal heart sounds that you expect to hear when listening for the opening and closing of the BPS. Uh The first one lab also called S one is caused by the closure of the A V valves and the dup or S two is the closure of the aortic and pulmonary valves. So those are normal sounds you hear in a healthy heart as it goes through its cardiac cycle. And therefore, also choice D both A and B is incorrect. So the sound you'd expect to hear through or you may hear with a stethoscope and a person with aortic valve stenosis. This choice see a murmur. See you in the next video.
