Hi slindblade. I'm not much of an expert on anything in particular. However, I feel that I qualify to offer an opinion or two about diving with a pfo, as well as the pros and cons of closure. Funny, I just realized that I am "Ann" from the DAN study. LOL! Yes, I am a study participant and don't mind sharing my personal medical information if it can help a fellow diver continue to share the passion. I was getting bent so frequently that closure of the pfo was really the only solution for me to continue diving. Diving conservatively really wasn't a reasonable option for me. I continue to work as a divemaster on my days off and the depths and profiles in Jupiter don't really allow for conservative diving. I was extremely fortunate to connect with Doug Ebersole, who in a single day, saw me, tested me, diagnosed me, and scheduled my pfo closure. WOW. I know that's not typical service in medicine, but this guy really takes care of fellow divers. Since my procedure just over 2 years ago, I have made approximately 500 dives, mostly to depths in the 80 to 100 foot range. I have made several dives to 130 + feet, including repetitive dives in the 100 ft. range. I have not had a single episode of DCS since my closure. My results may not be typical. I got back in the saddle very quickly, even more quickly than the good doctor would have liked. Ha Ha!
Pros: DCS episodes are completely gone even with deeper and more repetitive diving, my circulation has improved: cold and burning hands and feet turning red and white (diagnosed Reynaud's) completely disappeared immediately after PFO closure and has not returned.
Cons: Had to take a day off work for testing, procedure, and follow-up. Three whole days to get my diving life back. Night in the hospital with an impossible and whiney roommate. Expensive if your insurance won't cover it. Mine did but I still had a $1500 co-pay. Taking plavix for three months and looking like a bruised and battered wife. Irregular heartbeat about 6 weeks after the procedure that lasted a couple of months. By far, the biggest con was not being allowed to dive for 3 months after the procedure. I lasted exactly 5 weeks and 2 days before I just had to make a dive. I was becoming dangerous to those around me.
