No, my recommendations are the same today as back then as there is no new data to suggest a new approach. I still feel recreational divers who are found incidentally to have a PFO can safely dive. They, like all divers, should practice conservative diving with slow ascents, safety stops, etc. On the other hand, if a diver has had multiple "unexpected" DCS events and is found to have a large PFO, I feel it is reasonable (though admittedly controversial in the medical community) to offer closure to those divers. I have personally closed about 25 divers with multple "unexpected" DCS events and, anecdotally, they are doing well. However, these are still anecdotes and not data. What we need is good research information which is what Dr. Denoble and I are doing with the DAN-sponsored PFO study.
