Anatomical assessment of congenital heart disease.
Cardiac MRI (CMR) is replacing diagnostic cardiac catheterization as the modality of choice for anatomic and functional characterization of congenital heart disease (CHD) when echocardiographic imaging is insufficient. In this manuscript, we discuss the principles of anatomic imaging of CHD, placing emphasis on the appropriate choice and modification of pulse sequences necessary to evaluate infants and small children. Clinical examples are provided to illustrate the relative strengths and shortcomings of different CMR imaging techniques. Although cardiovascular function and flow techniques are not described, their role in evaluating the severity of anatomic defects is emphasized. Anatomic characterization represents the first component of a carefully-planned, integrated CMR assessment of CHD.
