My recent thoracic mri for scoliosis shows right-sided aortic arch& right-sided descending thoracic aorta..possible congenital heart dis. can u die ?

Chill out: If you lived to the ripe age of 31 before finding out you had this anomaly, you will likely live a full life without problems. The process is likely a "laterality sequence". This originates early in fetal formation. Those with bad heart defects show up early in life. You need further study, and consultation with a geneticist. The worst of these is more common in males.

Possible: But need more info. A right-sided arch is considered a normal anatomic variant if there are no other defects. This lesion alone will not cause problems. If you have any symptoms or concerns, speak with your primary doctor about obtaining more details of your cardiac anatomy. Again though, an isolated right arch without any narrowing is a normal anatomic variant (though it is relatively rare).
