Title: Coronary
CT Angiography (CCTA) and the role of structured reporting in contemporary CAD
management
🔬 Presentation Overview
🫀 Understanding Coronary CT Angiography (CCTA)
Coronary Computed Tomography Angiography (CCTA) is a non-invasive, rapid,
and cost-effective cardiac imaging modality that plays a key role in the early
detection, diagnosis, and risk stratification of Coronary Artery Disease (CAD).
By combining CT imaging with intravenous iodine-based contrast, CCTA enables
detailed visualization of coronary artery anatomy and plaque burden.
CCTA is recommended for patients presenting with acute chest pain to exclude
significant obstructive CAD, as well as for intermediate- to high-risk patients
with stable chest pain.
⚙️ Imaging
Technique and Patient Preparation
High-quality diagnostic imaging depends on optimizing both technical and
patient-related factors. Pharmacological heart-rate control using beta-blockers
is commonly employed when heart rates exceed 65 beats per minute, while
nitroglycerin is administered to promote coronary vasodilation.
Patients are advised to avoid caffeine and certain medications (such as
phosphodiesterase inhibitors) before the scan. Breath-holding during image
acquisition is essential to minimize motion artifacts. In addition to coronary
assessment, CCTA can detect extracardiac findings, including aortic pathology
and pulmonary embolism.
📊 Structured
Reporting with CAD-RADS 2.0
Standardized interpretation of CCTA findings is achieved using the Coronary
Artery Disease–Reporting and Data System (CAD-RADS) 2.0. This structured
reporting framework ensures clear communication between radiologists and cardiologists
and supports consistent clinical decision-making.
CAD-RADS 2.0 categorizes coronary stenosis severity from 0 to 5 and
incorporates overall plaque burden grading (P1–P4), providing a comprehensive
overview of disease extent.
🧬 Key Modifiers Enhancing Risk Assessment
CAD-RADS 2.0 includes modifiers that add important prognostic and functional
insights:
·
HRP (High-Risk Plaque): Applied
when two or more high-risk plaque features are present, such as low-attenuation
plaque, positive remodeling, spotty calcification, or the napkin-ring sign. HRP
is associated with an increased risk of acute coronary syndrome, independent of
stenosis severity.
·
I (Ischemia): Used when
non-invasive functional assessments—such as CT-derived fractional flow reserve
(CT-FFR) or stress CT perfusion (CTP)—demonstrate the hemodynamic significance
of a coronary lesion, particularly in CAD-RADS 3 or 4A categories.
🩺 Clinical Impact in Modern CAD Management
CCTA offers a safe, non-invasive alternative to invasive coronary angiography
(ICA), eliminating catheter-related risks and reducing recovery time. By
integrating anatomical stenosis severity, plaque vulnerability, and functional
significance, the CAD-RADS 2.0 framework enables radiologists to deliver
actionable, clinically relevant information.
This approach supports cardiologists in selecting the most appropriate next
steps—whether functional testing or ICA—especially in patients with moderate to
severe coronary stenosis (CAD-RADS 4A/4B).
