Insights
Congenital coronary arteriovenous fistulas often present without typical heart disease symptoms. Coronary arteriography is crucial for diagnosing these rare vascular anomalies.
Area of Science:
- Cardiology
- Vascular Surgery
- Diagnostic Imaging
Background:
- Congenital coronary arteriovenous fistulas are rare vascular malformations.
- Patients may lack characteristic cardiopathy symptoms.
- Standard diagnostic tests like ECG and X-rays offer limited specificity.
Purpose of the Study:
- To describe the clinical presentation and diagnostic approach for congenital coronary arteriovenous fistulas.
- To highlight the role of specific physical examination findings and imaging in diagnosis.
Main Methods:
- Case series review of five patients with congenital coronary arteriovenous fistulas.
- Clinical examination, including auscultation for murmurs.
- Coronarography for anatomical and topographical diagnosis.
Main Results:
- Patients presented with nonspecific symptoms.
- A continuous systolic-diastolic murmur was a key auscultatory finding.
- Coronarography successfully identified the fistulas and their origins.
Conclusions:
- Congenital coronary arteriovenous fistulas require a high index of suspicion due to atypical presentations.
- A characteristic murmur can suggest the diagnosis.
- Coronarography remains the gold standard for definitive diagnosis and localization.
Abstract:
The authors examined and operated on five patients with congenital coronary arteriovenous fistulas. Patients suffering from this disease do not exhibit complaints typical of cardiopathy and the results of electrocardiographic and roentgenographic examination lack specific features. The presence of low systolic-diastolic murmur suggests a common arteriovenous coronary orifice and by means of coronarography it is possible to make a topical diagnosis.
