Right-to-left shunt and migraine: the strength of the relationship
This one has been a hot topic with the cardiologists lately. A whole new set of patients to perform procedures on. However, I do not feel that we have all the questions answered yet. Here is the scenario…it was found that a large number of patients in whom the opening between the right and left ventricles in the heart had never closed (in the fetus, the lungs aren’t used so the blood bypasses the lungs via this hole) had migraine headaches. In some cases, these headaches resolved when the hole was surgically closed. So here’s some additional thoughts/concerns.
