Abstract
Congenital heart disease is one of the most difficult areas of
diagnostic radiology because of the small patient body size and fast
resting heart rate.
Accurate, 3D evaluation of the intra cardiac and extra cardiac
vascular anatomy is critical for the clinical management and surgical
planning of conotruncal anomalies.
Echocardiography is the first-line modality of cardiac imaging. It is
available, non-invasive and provides immediate high-resolution
anatomical and physiological information. However, Echo is limited in
assessment of extracardiac defects.
Cardiac catheterization has traditionally been the procedure utilized
to complement echo, providing hemodynamic information and enabling
visualization of extracardiac great vessels. However, its role in pediatric
cardiology is declining due to the invasive nature of catheterization and
the exposure to radiation. In many centers, cardiac catheterization is now
reserved for patients in whom hemodynamic data is essential and/ or in
whom interventional procedures are necessary.
Recently, the advancements in spatial and temporal resolution of
multidetector CT (MDCT) have evolved so that congenital heart disease
can be precisely diagnosed.
The current study was designed to evaluate the role of MDCT in
the assessment of conotruncal anomalies, it continued from July 2015 to
October 2017 and enrolled 50 patients (29 males and 21 females) with an
age range between 3 days - 17 years (mean age 14.8±37.5 months).
