CMR for transposition of the great arteries

Abstract

In this chapter, a cardiovascular magnetic resonance (CMR) imaging approach to complete transposition of the great arteries after atrial redirection (Mustard or Senning operation) or arterial switch surgery is discussed, as well as the Rastelli procedure for transposition of the great arteries, ventricular septal defect, and pulmonary stenosis. Congenitally corrected transposition of the great arteries, either unoperated or following anatomical or physiological repair, is also described. In these conditions, CMR is acknowledged to have high utility, including for accurate quantification of right, as well as left, ventricular function, to enable imaging of the aorta and pulmonary arteries, baffles, and conduits, and for the identification of myocardial fibrosis. Information from CMR aids prognostication and planning of intervention.
