An MRI to test for HCM says There is a tortuous descending aorta. There is an aberrant right subclavian artery which courses posterior to the trachea?

MRI answers nothing. The MRI answers nothing about HCM. The descending aorta being tortuous points to a long history of hypertension, smoking, and/or high cholesterol. The right subclavian normally passes in front of (not behind) the windpipe. This anomaly probably doesn't mean much, u were probably born with it. With HCM, you want to get an idea of how narrow the outflow tract (aortic valve) is, which is not given.

What exactly does it mean to have an anomalous origin to the right subclavian artery, arising from distal aortic arch?

Anatomy. Although i can define this for you, I am unaware of the clinical implications. There are three main arteries which project from the aortic arch -- the brachiocephalic trunk (which splits to form the right subclavian artery and right common carotid); left common carotid; and left subclavian. Anomalous origin means that the artery is arising from an anatomically unusual location. Read more...
Anatomy. In the picture you see the aortic arch and the 3 vessels coming off. These are the innominate, left carotid and left subclavian. The proximal aorta is coming from your heart and the distal aorta is heading away to your body. Usually the right subclavian would come off the innominate. Yours, probably due to a developmental quirk, comes distal directly off the aorta. Read more...
