Does persistent (patent) foramen ovale closure reduce the risk of recurrent decompression sickness in scuba divers?

Interatrial communication is associated with an increased risk of decompression sickness (DCS) in scuba diving. It has been proposed that there would be a decreased risk of DCS after closure of the interatrial communication, i.e., persistent (patent) foramen ovale (PFO). However, the clinical evidence supporting this is limited.Medical records were reviewed to identify Swedish scuba divers with a history of DCS and catheter closure of an...
