Insights
Coronary artery fistulas (CAFs) are rare congenital anomalies. Conservative management is recommended for asymptomatic patients with CAFs, guided by imaging and fistula characteristics.
Area of Science:
- Cardiology
- Congenital Heart Disease
Background:
- Coronary artery fistulas (CAFs) are uncommon congenital heart defects.
- They can cause angina or heart failure due to coronary steal phenomenon.
Background:
Coronary artery fistulas (CAFs) are rare congenital anomalies that may present with symptoms of angina or heart failure due to a coronary steal phenomenon. Diagnosis and treatment are based on symptom severity and anatomical characteristics.
Case Summary:
A 68-year-old man presented with chest pain. He had no obstructive coronary disease on coronary computed tomography angiography, but the left circumflex artery was found to be ectatic and draining into the coronary sinus, consistent with a congenital fistula. No evidence of ischemia or shunt was seen on the imaging assessment. The patient was managed conservatively, and he remained asymptomatic during 1 year of follow-up.
Conclusions:
Management of CAFs is decided on factors including symptoms and fistula characteristics, leading to a conservative, transcatheter, or surgical approach.
Take-Home Messages:
Detailed multimodality imaging assessment in CAFs is required. Conservative management is generally recommended in asymptomatic patients.
