Answer:
Although there are some hereditary or congenital causes of aortic stenosis, most commonly it occurs with age as the aortic valve accumulates calcium deposits leading to the obstruction. It is important that you see your physician regularly and especially if you have any new cardiovascular symptoms. Your doctor should do a complete physical exam including listening to the heart to assess for the presence of any cardiac murmurs. If a murmur is present, the doctor may order imaging studies such as an ultrasound of the heart to assess for the presence of aortic stenosis.
I would disagree with the idea that most heart exams are geared for men more than women. The usual tests ordered to evaluate for cardiovascular disease or valvular heart disease (such as aortic stenosis) do not make any gender distinction. I would encourage women to see a female doctor or cardiologist only if they would feel more comfortable doing so, not because of perceived cardiac testing bias.
