title: U.S. navy diver/aviator/skydiver with AGE from a previously unknown PFO.
abstract: A 32 year old US Naval aerospace physiologist with dive, jump and flight qualifications presented to a US Navy hyperbaric medicine department complaining of nausea, unsteadiness and left hand and forearm paresthesia that began almost immediately after completing a 28ft/ 40min recreational dive. Following an abbreviated history and physical examination the patient was diagnosed to be suffering from an arterial gas embolism. He was treated with hyperbaric therapy during which his symptoms resolved. Follow-on transesophageal echocardiography revealed an atrial septal aneurysm with a patent foramen ovale resulting in a right-to-left shunt after Valsalva maneuver, but no evidence of ventricular dysfunction, wall motion abnormalities, or abnormal ejection. His episode was attributed to paradoxical air embolism and he was disqualified from further special duty. In order to regain his dive, jump and flight qualifications, the patient elected to undergo repair of the cardiac defect with a device that is relatively new in the operational military setting. The procedure was a success, he was granted waivers for his prior qualifications, and remains in that status to this day. This is the first known case where an atrial septal occluder has been used to preserve these special duty qualifications.
