blood pressure problem

From GS-7 BS

"Mitral valve stenosis is a disorder in which the valve opening between the left atrium and the left ventricle is narrowed enough to cause a decreased blood flow between those two chambers of the heart. As a result of mitral valve stenosis, blood pressure would be elevated in all of the following structures EXCEPT the:


a aorta.
b left atrium.
c pulmonary capillaries.
d pulmonary arteries.





answer: Decrease blood flow to the left side of the heart means decreased blood flow to the main vessel which leaves the left side of the heart: the aorta. "

my question is if there's less blood flow, wouldn't there be lower pressure in all of those components?

If the valve is malfunctioning, blood will just crowd up in the left atrium and hence more blood will back up into the pulmonary vessels and hence greater pressure exerted in those vessels.
Not a lot of blood will flow into the left ventricle and beyond, so lower pressure in left ventricle (during diastole), aorta, and subsequent arteries.
