Insights
Congenital heart defects can cause infant heart failure. A rare right coronary artery to right ventricle fistula caused a significant left-to-right shunt, leading to congestive heart failure in an infant.
Area of Science:
- Pediatric Cardiology
- Congenital Heart Disease
- Cardiovascular Surgery
Background:
- Infant heart failure is often due to left-to-right shunts causing pulmonary overcirculation.
- Identifying the precise cause of shunting is crucial for effective treatment.
Abstract:
Heart failure in early infancy is commonly caused by lesions leading to pulmonary over circulation secondary to left-to-right shunt. This case report describes an unusual cause of significant left-to-right shunt in a 2 months old infant presenting with congestive heart failure, which was diagnosed with transthoracic echocardiography. In this infant, transthoracic echocardiography with Doppler color flow mapping allowed direct visualization of a large right coronary artery to right ventricular fistula that was surgically corrected successfully.
