Part 2 of 3 about my most recent blood clotting ordeal. Go here for part 1 . Dr. Foley ordered an echocardiogram bubble test to check if there was a hole in my heart between the two upper chambers. It's actually a common occurrence that affects upwards of 25% of the population and is referred to as PFO, or Patent Foramen Ovale. It can lead to a DVT (deep vein thrombosis clot) moving from the venous side of the heart to the arterial side which appears to possibly be what happened in my case. Without a PFO, the chances for a DVT posing a stroke risk just aren't there. The clot moves via the veins back to the heart and into the lungs where it's stopped and results in a pulmonary embolism or PE. Where a PFO is present, the clot may migrate to the arterial side of the heart and work its way to the brain and cause a stroke or it may become lodged in any number of places as the clot is carried along via the arteries. In my case, a clot became wedged in the popliteal artery.
