Overview
ACC/AHA guidelines recommend certain tests to evaluate and follow up in patients with levo-transposition of the great arteries

==(ACC/AHA) recommendations for evaluation and follow-up of patients with congenitally corrected transposition of the great arteries (CCTGA) (DONOT EDIT)==

Class I

1. All patients with CCTGA should have a regular follow-up with a cardiologist who has expertise in adult congenital heart disease (ACHD). (Level of Evidence: C)

2. Echocardiography-Doppler study and/or magnetic resonance imaging (MRI) should be performed yearly or at least every other year by staff trained in imaging complex congenital heart disease (CHD). (Level of Evidence: C)

3. The following diagnostic evaluations are recommended for patients with CCTGA:
 * 1. Electrocardiogram (ECG). (Level of Evidence: C)
 * 2. Chest x-ray. (Level of Evidence: C)
 * 3. Echocardiography-Doppler study. (Level of Evidence: C)
 * 4. MRI. (Level of Evidence: C)
 * 5. Exercise testing. (Level of Evidence: C)

Interventional Therapy

Recommendations for Catheter Interventions

Class IIa

1. For patients with unrepaired CCTGA, cardiac catheterization can be effective to assess the following:
 * 1. Hemodynamic status in the setting of arrhythmia. (Level of Evidence: C)
 * 2. Unexplained systemic ventricle (SV) dysfunction, to define the degree of systemic AV valve regurgitation, degree of intracardiac shunting, and coronary artery anatomy. (Level of Evidence: C)
 * 3. Unexplained volume retention or cyanosis, especially when noninvasive assessment of pulmonary outflow obstruction is limited. (Level of Evidence: C)
