Coronary artery fistula connecting the left main coronary artery with the superior vena cava

Area of Science:

• Cardiology
• Medical Imaging

Background:

• Coronary artery fistulas are uncommon congenital defects.
• These anomalies involve abnormal connections between coronary arteries and cardiac structures.

Observation:

• A large coronary artery fistula was identified.
• The fistula connected the left main coronary artery to the superior vena cava.

Findings:

• The patient, aged 70, presented with non-ST-segment elevation myocardial infarction.
• Diagnostic coronary angiography revealed the fistula.
• The patient opted against fistula closure and remained asymptomatic.

Implications:

• Accurate angiographic diagnosis of coronary artery fistulas is crucial.
• This case underscores the importance of individualized patient management.
• Conservative management can be a viable option for asymptomatic patients with coronary artery fistulas.
