This case report details multiple coronary artery fistulae causing biventricular hypertrophy. Echocardiography and coronary angiography confirmed the diagnosis and drainage into both ventricles.
Area of Science:
- Cardiology
- Medical Imaging
- Congenital Heart Disease
Background:
- Coronary artery fistulae are rare congenital anomalies.
- Biventricular hypertrophy can result from abnormal blood flow in the heart.
Purpose of the Study:
- To report a unique case of multiple coronary artery fistulae with biventricular hypertrophy.
- To highlight diagnostic modalities for this rare condition.
Main Methods:
- Diagnosis initiated with transthoracic 2-dimensional and Doppler echocardiography.
- Coronary angiography was performed for definitive diagnosis.
- Imaging focused on identifying fistulae and their drainage pathways.
Main Results:
- Multiple coronary artery fistulae were identified.
- Fistulae were observed to drain into both the left and right ventricles.
- The condition was associated with biventricular hypertrophy.
- Coronary angiography revealed persistent sinusoids connecting fistulae to the left ventricle.
Conclusions:
- Multiple coronary artery fistulae can present with biventricular hypertrophy.
- A combination of echocardiography and coronary angiography is crucial for diagnosis.
- This case expands understanding of coronary artery anomaly presentations.
