Comparison of transthoracic echocardiography versus cardiovascular magnetic resonance imaging for the assessment of ventricular function in adults after atrial switch procedures for complete transposition of the great arteries.

Adult patients with a history of transposition of the great arteries and atrial switch operation were studied with transthoracic echocardiography and cardiovascular magnetic resonance imaging. Measurements of ventricular dimensions and function by these 2 techniques in 18 consecutive patients were well correlated.
