Abstract
Abstract:
Congenital left ventricular outflow obstruction represents a multilevel obstruction with
several morphological forms. It can involve the subvalvular, valvar, or supravalvular portion of the
aortic valve complex, and may coexist. Computed tomography (CT) plays an important supplementary
role in the evaluation of patients with congenital LVOT obstruction. Unlike transthoracic
echocardiography and cardiovascular magnetic resonance (CMR) imaging, it is not bounded by a
small acoustic window, needs for anaesthesia or sedation, and metallic devices. Current generations
of CT scanners with excellent spatial and temporal resolution, high pitch scanning, wide detector
system, dose reduction algorithms, and advanced 3-dimensional postprocessing techniques
provide a high-quality alternative to CMR or diagnostic cardiac catheterization. Radiologists performing
CT in young children should be familiar with the advantages and disadvantages of CT and
with the typical morphological imaging features of congenital left ventricular outflow obstruction.
