Patent Foramen Ovale - A button closure (Amplatzer) is performed trans venously without entering the chest. Four weeks after the surgery, another echocardiogram is done to verify that the device is still in position.

After two-three weeks there is an overgrowth of endothelial cells covering the device, reducing the risk of infection.

After six to eight weeks the connective tissue has completely filled the spaces in the device and it becomes invisible to ultrasound. Return to diving is usually in six weeks (Wilmshurst), given the full recovery to the satisfaction of the cardiologist/surgeon. Others require a longer wait of twelve weeks.
