Key result
Non-invasive imaging modalities, including advanced echocardiography, CT, MRI, and 3D printing, have revolutionized the diagnosis, treatment planning, and surveillance of congenital heart disease.
Advanced non-invasive imaging modalities and 3D printing have revolutionized the diagnosis and management of congenital heart disease in Hong Kong, significantly reducing the reliance on invasive diagnostic cardiac catheterization.
May reduce invasive catheterization in congenital heart disease; leaves open need for prospective outcome trials.
Congenital heart disease (CHD) is a major global health issue. In Hong Kong, left-to-right shunting, pulmonary outflow obstruction including tetralogy of Fallot, followed by left ventricular outflow obstruction and coarctation of aorta, are the most commonly encountered congenital heart defects. Imaging has played an important role in the diagnosis, treatment planning, and follow up of patients with CHD. The advances in the techniques of non-invasive imaging modalities have led a revolutionary change in the diagnosis and management of CHD. Advanced echocardiography e.g., speckle tracking technique, pixel tracking technique, velocity vector imaging, and 3-dimensional (3D) echocardiography; computed tomography; and magnetic resonance imaging have been widely applied. The field of 3D printing has superb advantages in illustrating complex congenital heart defects, and thus allows individualized modeling and accurate treatment planning.

Tse et al. (2017) conducted a review in Congenital heart disease. Non-invasive cardiac imaging (Echocardiography, CT, MRI, 3D printing) vs. Invasive cardiac catheterization was evaluated. Non-invasive imaging modalities, including advanced echocardiography, CT, MRI, and 3D printing, have revolutionized the diagnosis, treatment planning, and surveillance of congenital heart disease.
