You have probably used Valsalva from time to time, or exerted yourself during a dive. >If I have a huge gaping hole in my heart, I guess I start coming up even >slower.

I would still dive, but I would probably convert my 120 to NITROX service, use EAN 36 (as I would probably not dive deep anymore), dive on my air computer (Dacor Omni Pro), and use an EAN 50 pony for the ascent. This seems to me to be a REALATIVELY low cost option to an arguably more risky set of conditions (medical predisposition). I wonder what DAN*s position would be if a diver knowingly dives with a PFO without taking extra measures. Then again, the person may not understand the risk of diving with a PFO.
