Where in the heart does aortic stenosis occur (2 points) Second paragraph in article: Aortic stenosis leads to left venticular (LV) hypertrophy and increased resistance to LV filling. With the knowledge gained in class, describe why this will occur. (5 points) Address the concept of afterload. 1. 2. . Why will aortic stenosis affect coronary blood supply? (2 points) 4. Using a stethoscope, where will the problem be heard? ( 2points) 5. What will normall occur to Cardiac output? Stroke volume ? Heart rate?Explanation / Answer
1.Aortic stenosis is a commonand most serivous valve disease.
It is narrowing of the heart valve and restricted blood flow supply.
It restricts the blood flow from the heart into theaorta and also rest of the body.
Progressive wear and tear of thebicuspid valve,scar in the aortoc valve due to fever.
3.because ofthe increase in the extra vascular compression because of prolonged systolic ejection in aortic stenosis, Decrease in cornoary blood flow was noted
4.it is a mid systolic ejectionmurmur heard best over the aortic area or in the right second intercostal space.
5.Stoke volume decreases, increase in end systolic volume and increase in ventricular stress.
