| Summary: | Congenital heart disease (CHD), which affects 1% to 2% of all births, is the most common abnormality in women contemplating pregnancy in western countries. With diagnostic and interventional advances, most patients with CHD survive into adulthood and require lifelong cardiac follow-up with cardiac imaging, particularly echocardiography and cardiac computed tomography. Multiple hemodynamic and physiologic changes of pregnancy may predispose patients with CHD to clinical decompensation and an inability to tolerate pregnancy. This manuscript reviews common CHD lesions, their repair or palliative interventions, long-term sequelae, important features to assess on cardiac imaging, and the impact of pregnancy on these types of lesions. Moreover, the review bridges the fields of CHD, cardiac imaging, and maternal cardiology, which will aid clinicians in counseling patients and managing pregnancies.
