A Giant Left Main Trunk and Left Circumflex Artery-to-Right Ventricle Fistula

Area of Science:

• Cardiology
• Vascular Surgery
• Medical Imaging

Background:

• Coronary artery fistulas (CAFs) are abnormal connections between a coronary artery and a cardiac chamber or great vessel.
• Fistulas involving the left main trunk and left circumflex artery are exceptionally rare.
• Understanding the clinical presentation and diagnostic modalities for rare CAFs is crucial for timely management.

Observation:

• A 24-year-old male presented with symptoms suggestive of a cardiac anomaly.
• Diagnostic imaging revealed a giant fistula originating from the left main trunk and left circumflex artery, draining into the right ventricle.
• Transthoracic echocardiography and coronary computed tomography angiography were instrumental in diagnosing the condition.

Findings:

• The patient was diagnosed with a giant left main trunk and left circumflex artery to right ventricle fistula.
• The diagnostic process highlighted the utility of non-invasive imaging techniques in identifying complex coronary artery anomalies.
• This specific fistula type presents unique anatomical and physiological considerations.

Implications:

• This case contributes to the limited literature on rare coronary artery fistulas.
• Enhanced understanding of clinical characteristics can improve diagnostic accuracy and patient outcomes.
• Further research into the management of such rare fistulas is warranted.
