Key result
Echocardiography remains the primary imaging modality for adults with transposition of the great arteries, though a multimodality approach is required for complete evaluation.
A multimodality imaging approach is necessary for the comprehensive evaluation of adults with transposition of the great arteries due to the limitations of echocardiography alone.

Multimodality imaging may supplement echocardiography for adult TGA evaluation; leaves open standardized protocols for prospective validation.
PURPOSE OF REVIEW: Patients with complete and congenitally corrected transposition of the great arteries commonly survive into adulthood and present with a vast array of clinical residua. RECENT FINDINGS: Echocardiography remains the primary imaging modality in the routine assessment of the adult with transposition of the great arteries. It provides a comprehensive anatomic and hemodynamic evaluation. Limitations to echocardiography include evaluation of the following: the systemic right ventricle, baffle patency following atrial switch procedure, coronary arteries following arterial switch procedure or Nikadoh, and multilevel right ventricular outflow tract obstruction. SUMMARY: Each form of palliation for transposition of the great arteries results in unique long-term sequelae that affect outcomes. A multimodality approach to imaging is required for a complete evaluation.

Anderson et al. (2017) conducted a review in Transposition of the great arteries. Echocardiography and multimodality imaging was evaluated. Echocardiography remains the primary imaging modality for adults with transposition of the great arteries, though a multimodality approach is required for complete evaluation.
