The peripheral artery studies showed the discordant pressure between my two arms, and my arteriogram showed 100% blockage of my left
subclavian artery. I had the arteriogram done because I was supposed to get a stent placed in my left subcalvian artery; however, once the doctor saw that it was 100% blocked, he decided against the procedure and referred me to a surgeon who specializes in heart diseases (he is board certified in vascular, thoracic, and cardiology).
