A Case of Coronary Cameral Fistula: When and How to Intervene?

Area of Science:

• Cardiology
• Cardiovascular Surgery
• Medical Imaging

Background:

• Coronary artery fistulas are rare anomalies connecting coronary arteries to cardiac chambers or great vessels.
• Most fistulas involve the right or left anterior descending coronary arteries; involvement of the circumflex artery is uncommon.
• This case highlights an unusual presentation of a circumflex coronary artery fistula.

Purpose of the Study:

• To report an unusual case of a coronary artery fistula.
• To describe the diagnostic imaging findings.
• To detail the surgical management and outcomes.

Main Methods:

• Case presentation of a middle-aged woman with heart failure symptoms.
• Diagnostic imaging included echocardiography and computed tomography angiography.
• Surgical intervention was chosen due to complex fistula anatomy.

Main Results:

• The fistula originated from the left circumflex coronary artery and drained into the right ventricle.
• Surgical repair was performed successfully.
• No early complications were observed, and follow-up at 1 year showed sustained recovery.

Conclusions:

• Surgical management can be effective for complex coronary artery fistulas, even those involving the circumflex artery.
• Early and long-term outcomes can be favorable with appropriate intervention.
• This case expands the understanding of rare coronary artery anomalies and their treatment.
