Congenital Heart Disease
Congenital heart disease (CHD) has an estimated incidence of 0.8% of all new live births globally, with significant geographic and income group differences, and a global prevalence of 0.4% in adults. The main classification schemes discriminate between acyanotic CHD, which initially do not interfere with the amount of oxygenated blood in the systemic circulation, and cyanotic CHD, which interfere with the amount of oxygenated blood in the systemic circulation. Most cyanotic CHD require surgical correction immediately or soon after birth due to high mortality rates.
Cardiac computed tomography (CT) enables an unsurpassed evaluation of the anatomy of patients with complex CHD, with nonrestricted volumetric imaging planes. In turn, cardiac magnetic resonance (CMR) provides accurate, reproducible, and ionizing-free data particularly useful for the evaluation of valves and shunts, including precise anterograde and retrograde volume quantification. CMR is particularly useful for the evaluation of the right ventricular morphology and function and for right-sided valvular disease.
