Normally, blood flows from the right side of the heart through the
pulmonary arteries and lungs before it returns to the left side of the heart. A
paradoxical embolism is a blood clot that does not travel with normal blood
flow. This type of embolism often causes a stroke because the clot moves
directly from the right side of the heart to the left through a hole (defect)
in the septum, which separates the upper right and left heart chambers. It then
bypasses the lungs and is pumped straight toward the brain.
