I now have been diagnosed with a Patent Foramen Ovale (PFO) heart defect.  Many times this will be evident at birth or early childhood but who knows of Germany hospital’s method for identifying defects or issues that may arise later in life.   Looking back during my young adulthood, I noticed signs such as trouble in endurance sports, frequent and temporary dimming of vision associated with low blood pressure during rest or the temporary numbness in my arms during daily strolls around the neighborhood.  In 95, I was told I had a heart murmur.  The last five years, I’ve had optic migraines which are visual disturbances without associated pain, shortness of breath, palpitations, not progressing in my cycling with increased training, and have become cynotic during exercise.  These symptoms have caused some concern.  The procedure to correct the PFO is a lot more simpler now, as open heart surgery has been replaced with a femoral artery cath procedure, where a cath containing a small closure device of material and metal is inserted into the hole defect and then secured in place.  Recovery is an over night hospital stay, 2 months of healing, 6 months of Coumadin and a lifelong prescription of aspirin.  I am waiting for my procedure to be scheduled.  UPDATE:  diagnosis of ASD or something else, recent results are now varied.
