It is the second most common coronary anomaly, and it can be life threatening if the right coronary courses between the great vessels ( aorta and pulmonary artery). This course can be checked on a CT scan or on a left heart catheterization with extreme lateral views. If that is the case there is a significant chance of sudden cardiac death and you should undergo surgical repair at an experienced tertiary care center. I would suggest that since this is not a common anomaly that you seek the opinion of an expert in this area at the nearest respected teaching facility.
i have had the ct and this is how the cardiologist confirmed it.She is currently researching it and on the 4th i ham to have a nci stress test to see if it is going to require immediate open heart surgery or if we can wait.i was told the right artery is going between the 2 main arteries in the middle of the heart.my question is how worried should i be? As i said she Dr STronach told me it is so rare that less than 1% 9More around .25 of a percent has it) is it really that rare?? thank you
