Surgical exclusion of a symptomatic circumflex coronary to right atrium fistula

Area of Science:

• Cardiology
• Cardiovascular Surgery
• Medical Imaging

Background:

• Coronary artery fistulas (CAFs) are uncommon congenital or acquired abnormalities.
• Approximately 50% of individuals with CAFs present with symptoms, including heart failure.
• Diagnosis relies on echocardiography, coronarography, and advanced imaging like multislice CT-scan.

Observation:

• A 56-year-old female presented with congestive heart failure.
• The cause was identified as a fistula between the proximal circumflex coronary artery and the right atrium.
• This coronaro-cardiac fistula led to significant cardiac compromise.

Findings:

• The patient underwent successful surgical exclusion of the fistula.
• The procedure involved ligation of the fistula's extremities and suturing of the involved vessel.
• Multislice CT-scan precisely located the fistula, aiding surgical planning.

Implications:

• Surgical intervention can effectively treat symptomatic coronary artery fistulas.
• This approach resolved heart failure symptoms and prevented fistula recurrence.
• Early and accurate diagnosis using advanced imaging is crucial for successful management.
