Coronary artery fistula draining into left ventricle: case report and review
Insights
A rare coronary artery fistula in a child was analyzed. Diagnosis requires retrograde aortography as clinical signs are nonspecific for this congenital heart defect.
Area of Science:
- Cardiology
- Pediatric Cardiology
- Congenital Heart Disease
Background:
- Coronary artery fistulas (CAFs) are uncommon congenital heart defects.
- Left ventricular (LV) drainage is a rare type of CAF.
- Clinical presentation of CAFs can be variable and nonspecific.
Observation:
- A case of a 6-year-old boy with a CAF draining into the left ventricle is presented.
- A review of 14 previously reported cases was conducted.
- Analysis focused on clinical manifestations, murmur characteristics, and electrocardiographic findings.
Findings:
- Clinical signs and symptoms are not specific for diagnosing coronary artery fistulas.
- Retrograde aortography is essential for definitive diagnosis of the anomaly.
- Specific features of systolic murmurs and electrocardiographic findings were discussed.
Implications:
- Improved understanding of the clinical spectrum of coronary artery fistulas.
- Highlights the diagnostic challenges and the importance of advanced imaging.
- Provides insights into the pathophysiology and diagnostic markers for this rare condition.
Abstract:
A 6-year-old boy with coronary artery fistula emptying into the left ventricle was reported. An attempt was made to outline clinical manifestations of this disease which have not yet been fully described, based on the experience of the present case and a review of 14 previously reported cases. It is concluded that clinical signs and symptoms are not specific for this anomaly and retrograde aortography is required to establish the definite diagnosis of the lesion. Authors' views are expounded as to the location of maximal intensity of the murmur, genesis of the systolic murmur and electrocardiographic features.
