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.
