Chest Discomfort: Could Coronary Pathology Extend Beyond Atherosclerosis?

Area of Science:

• Cardiology
• Radiology
• Medical Imaging

Background:

• Non-atherosclerotic coronary artery disorders can cause myocardial ischemia, presenting with non-specific symptoms.
• These conditions are frequently overlooked in radiological diagnoses.
• Early identification is vital for appropriate patient management.

Purpose of the Study:

• To highlight the utility of multidetector computed tomography (MD CT) coronary angiography.
• To review rare, non-atherosclerotic coronary artery pathologies.
• To emphasize MD CT's role in diagnosing these conditions.

Main Methods:

• Literature search on Medline (PubMed) for non-occlusive coronary artery pathologies.
• Narrative review summarizing imaging characteristics.
• Presentation of selected MD CT cases from clinical practice.

Main Results:

• Identified pathologies include myocardial bridge, coronary aneurysm, ectasia, fistula, stenosis, and dissection.
• MD CT effectively visualizes these non-occlusive findings.
• Case examples illustrate MD CT's diagnostic capabilities.

Conclusions:

• Non-atherosclerotic coronary abnormalities are important differential diagnoses for ischemic symptoms.
• MD CT is a valuable tool for non-invasive evaluation of these conditions.
• Consideration of these pathologies can improve diagnostic accuracy and patient outcomes.
