Radiologic evaluation of suspected congenital heart disease in adults.

Full Abstract

The population of adults with congenital heart disease is increasing in North America. Radiologic imaging is critical for the initial assessment and for surveillance in this population. Chest radiography and echocardiography are valuable first-line tools for evaluation. However, magnetic resonance imaging and computed tomography are often necessary, particularly for assessment of extracardiac anatomy or specific vascular connections or relationships, which may be complex in postoperative patients. Although magnetic resonance imaging and computed tomography can provide volumetric data for more comprehensive evaluation of cardiac anatomy and function, magnetic resonance imaging does not require patient exposure to ionizing radiation or nephrotoxic iodinated contrast media. Magnetic resonance imaging also can measure blood flow for quantification of left-to-right shunts, regurgitant fractions, and pressure gradients. Although noninvasive imaging techniques have limitations, they can evaluate most lesions and preclude the need for cardiac catheterization. Noninvasive imaging is particularly useful for serial evaluation of patients with surgically corrected congenital heart disease, because nearly one half of these patients will require two or more surgeries.
