Insights
Coronary fistulas, abnormal connections between coronary arteries and heart chambers or vessels, are rare congenital heart defects. This case highlights surgical correction for a 64-year-old female presenting with chest discomfort and syncope.
Area of Science:
- Cardiology
- Congenital Heart Disease
- Vascular Anomalies
Background:
- Coronary fistulas are rare anomalies involving abnormal communication between a coronary artery and a cardiac chamber, pulmonary artery, or veins.
- They account for 0.2–0.4% of congenital cardiopathies and 0.1–0.2% of adults undergoing coronary angiography.
Observation:
- A 64-year-old female presented with chest discomfort, dyspnea, and syncope.
- Diagnostic investigation revealed an undiagnosed coronary fistula.
Findings:
- The patient's symptoms were attributed to the coronary fistula.
- Surgical correction was deemed necessary for treatment.
Implications:
- This case underscores the importance of considering coronary fistulas in adult patients with cardiac symptoms.
- Surgical intervention, including pulmonary artery opening and extracorporeal circulation, can effectively manage this anomaly.
Abstract:
The coronary fistula is an anomaly characterized by the communication between a coronary artery and a cardiac chamber, pulmonary artery, coronary sinus and pulmonary veins. It represents 0.2 to 0.4% of the congenital cardiopathies and 0.1% to 0.2% of the adult population submitted to coronary angiography. We report the clinical case of a 64-year-old female patient, whose anomaly was diagnosed during a clinical investigation due to chest discomfort, dyspnea and syncope; the surgical correction was indicated, with opening of the pulmonary artery through extracorporeal circulation.
