Multiple congenital coronary artery fistulae draining into the left ventricle

Area of Science:

• Cardiology
• Vascular Medicine
• Congenital Heart Disease

Background:

• Coronary artery fistulas (CAFs) are abnormal connections between a coronary artery and a cardiac chamber.
• While CAFs are rare, multiple fistulas involving the left ventricle are exceptionally uncommon.
• This case focuses on a rare presentation of diffuse coronary artery-cardiac chamber communications.

Observation:

• An elderly woman presented with symptoms suggestive of coronary artery disease.
• Diagnostic coronary angiography revealed multiple, diffuse fistulous communications between coronary arteries and the left ventricle.
• The widespread nature of the fistulas precluded standard interventional approaches.

Findings:

• The patient was diagnosed with multiple diffuse coronary artery-left ventricular fistulas.
• Angiographic findings confirmed the extensive and widespread nature of the arteriovenous communications.
• The diffuse pattern of the fistulas presented a significant management challenge.

Implications:

• The case underscores the importance of comprehensive angiographic evaluation for complex coronary artery anomalies.
• Management strategies for diffuse coronary artery fistulas require careful consideration due to limitations of conventional treatments.
• This presentation suggests that conservative management may be the only option for certain extensive fistula cases.
