Bilateral coronary artery fistulas terminating at the same location case report

Area of Science:

• Cardiology
• Cardiovascular Surgery
• Medical Case Reports

Background:

• Coronary artery fistulas (CAFs) are abnormal connections between coronary arteries and heart chambers or great vessels.
• While CAFs are uncommon, bilateral involvement with termination in the pulmonary artery is exceptionally rare.

Observation:

• This report presents a unique case of bilateral coronary artery fistulas.
• The fistulas originated from both the left anterior descending artery and the right coronary artery.
• Both fistulas terminated at the identical site within the pulmonary artery.

Findings:

• The case involved a small saccular aneurysm formation at the termination site of the fistulas in the pulmonary artery.
• This specific anatomical configuration of bilateral coronary artery fistulas to the pulmonary artery is not previously well-documented.

Implications:

• Understanding rare anatomical variations like these bilateral coronary artery fistulas is crucial for accurate diagnosis and surgical planning.
• This case highlights the importance of detailed imaging in identifying complex congenital heart anomalies.
