Overview
Cardiac catheterization is not frequently done to diagnose transposition of the great vessels, as it could be done confidently with echocardiography. It is in conditions when the echo findings are inconclusive. It can be used to determine the coronary anatomy.

==The(ACC/AHA) recommendations for Catheter Interventions of patients with Congenitally corrected transposition of the great arteries (CCTGA) (DONOT EDIT)==

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)
