I was around 52 when I had it done. I was only in the hospital 1 night. I think if they keep you less than 24 hours it still qualifies as outpatient. My memory has faded a bit but I’m pretty sure I was back to work the next week. I have a desk job though and of course had to keep the Cath in until it was pulled after a week or so. As with my other procedures, the pain wasn’t an issue, just took some Advil as needed.
