Coronary artery fistula; coronary computed topography--the diagnostic modality of choice

Area of Science:

• Cardiology
• Vascular Anomalies
• Medical Imaging

Background:

• Coronary artery fistulae (CAF) represent rare vascular communications between coronary arteries and cardiac structures.
• These anomalies can exhibit significant variability in their anatomical course.
• Accurate diagnosis is crucial for appropriate management.

Observation:

• A unique case of a coronary artery fistula involving the left circumflex coronary artery and both the right and left atria is presented.
• The fistula's complex pathway and its connection to multiple cardiac chambers were detailed.
• This case underscores the anatomical diversity of coronary artery fistulae.

Findings:

• Traditional diagnosis of CAF often relies on coronary angiogram.
• Coronary Computed Tomography Angiography (Coronary CTA) offers non-invasive visualization of CAF.
• Coronary CTA provides enhanced accuracy in delineating the course and communications of these fistulae.

Implications:

• Advanced imaging like Coronary CTA improves the diagnostic capabilities for rare coronary artery anomalies.
• Non-invasive assessment aids in precise anatomical understanding, crucial for surgical or interventional planning.
• This case contributes to the understanding of rare CAF presentations and diagnostic advancements.
