Congenitally corrected transposition of the great arteries
For people without heart rhythm disturbances or any other symptoms relating to congenitally corrected transposition of the great arteries arteries, regular observation and monitoring by a congenital cardiologist may be all that is needed. A typical evaluation would include a thorough physical exam, electrocardiogram, chest X-ray, echocardiogram, and an exercise test. A Holter monitor or event recorder may also be used to check for irregular heart rhythms. More detail about these tests can be found in the Testing section.

Treatment for congenitally corrected transposition of the great arteries is highly individualized. Abnormally slow heart rhythms, which are common in these patients, are treated by implanting a pacemaker. Medications such as digitalis and antiarrhythmics may be prescribed to improve the pumping capabilities of the right ventricle and reduce the effects of a leaky valve when necessary. In some patients, surgery may be needed to replace valves where regurgitation develops. This should be performed before the ventricle becomes weak and before patients develop significant symptoms. More information is available in the section on Treatment for Valve Regurgitation Valve Regurgitation.
