Yes, there was a discharge note where they explained where the stents were placed, and why. Also how they hoped to treat a third block. But I don't remember any terms I could understand.
Before the procedure, there was an angiogram, that was a half-hour thing under local anaesthetic, two days after I was admitted (they were trying to get my BP within control). Immediately afterwards, the surgeon came to see me, told me that he would place two stents, and that it would be a very simple thing, with few complications. That was on the 18th; on the 21st, he placed the stents, again, under local anaesthetic. Unlike the angiogram, this was rather painful in terms of strain on muscle and sinews, and left bruises, but truth to tell, I was walking the second day; in fact, I was discharged the second day.
