Hi pickaback2 and welcome to this forum. You can learn a lot here. I have not had any OHS since my aortic valve was implanted in 1967 but I do visit with OHS patients, post-op, weekly as a hospital volunter. One of the really big changes I've noticed is post-op time in the hospital. I was in the hospital 14 days after my surgery and the inpatient time is now about half of that....4-6 days. Patients today are up and walking after a day or so rather than the several days in ICU in the '60s. Medications are now available for just about anything.....however I remember liking my "old time" diuretic a lot more than the newer diuretic drugs.....I got a 12oz can of beer every night LOL. It still is major surgery but a lot of the major "unknowns" seem to have been resolved. There are many on this forum that have have had re-ops and I'm sure they can add a lot based on their experiences.
