By Mayo Clinic staffIf you know you have a patent foramen ovale, but don't have symptoms, you probably won't have any restrictions on your activities.
But, be sure to consult your doctor before undertaking activities that might limit your levels of oxygen, such as scuba diving or mountain climbing. People with a patent foramen ovale may be more likely to get decompression sickness when scuba diving or a life-threatening form of altitude sickness called high-altitude pulmonary edema when mountain climbing.
