Congenital Extra-cardiac Vascular Anomalies as Detected on Multislice Computed Tomography Angiography
Taisir Jamal Aldeen Alsalihi;
Abstract
Congenital heart disease (CHD) is one of the troublesome issues in pediatric imaging considering small geometry of patient’s body, problematic cardiovascular morphology and rapid circulation. Cardiac imaging provides anatomical and functional information fundamental for treatment and follow-up complications following interventions and surgical procedures.
Echocardiography is the first line modality for diagnosis and management of CHD as it’s portable, readily available, non - invasive and provides instant high-resolution physio-anatomical information. Nevertheless, it is hampered by the acoustic window, spatial resolution, and operator dependency. Moreover, it fails to portray anatomical details of extra-cardic vascular structures yielding only 80% diagnostic accuracy.
Cardiac catheterization is famous as the gold-standard technique in diagnosing neonatal CHD. It complements echocardiography while providing hemodynamic information and permitting depiction of extra-cardiac vessels, yet it’s an invasive procedure that harbors risk of ionizing radiation as well as iodinated contrast media anaphylaxis. Although MRI clearly demonstrates intracardiac anatomy, flow dynamics and function, it is time-consuming, necessitates sedation or general anesthesia and of limited availability.
Owing to technologic advances in multi-slice CT encompassing high spatial and temporal resolution while reducing cardiac and respiratory motion artifacts, fast data acquisition as well as superb anatomic and functional assessment capabilities, it has been added to the armamentarium for imaging CHD.
The primary role of CT is non-invasive evaluation of extra-cardiac systemic and pulmonary arterial and venous structures and post-treatment complications, usually as an adjunct to echocardiography. High-quality 2D reformatted and 3D reconstructed CT images harmonize with axial images assisting in the comprehension of complex heart anomalies. Also, it’s capable of demonstrating vessel walls, airway delineation, adequate characterization of mediastinal abnormalities, and the pulmonary parenchyma. Furthermore; ECG-gated CT provide quantification of ventricular function and visualization of valve movement.
