[Congenital coronary fistula to right ventricle. Treatment with transcatheter coil embolization]

Area of Science:

• Cardiology
• Pediatric Cardiology
• Interventional Cardiology

Background:

• Congenital coronary artery fistulas are rare anomalies.
• Right coronary artery to right ventricle fistulas represent a subset of these anomalies.
• Diagnosis and management require advanced imaging and interventional techniques.

Observation:

• A 3-year-old girl presented with a congenital right coronary artery-right ventricle fistula.
• Diagnosis was confirmed using two-dimensional echocardiography with color-flow Doppler, cardiac catheterization, and angiography.
• The fistula involved an abnormal connection between the right coronary artery and the right ventricle.

Findings:

• Percutaneous transcatheter embolization was performed as the treatment modality.
• Two detachable coils (7 mm x 20 cm and 6 mm x 20 cm) were used for embolization.
• The procedure resulted in successful and complete occlusion of the fistula.

Implications:

• Transcatheter embolization is a viable and effective treatment for congenital coronary artery-right ventricle fistulas in children.
• This minimally invasive approach avoids the need for open-heart surgery.
• Successful occlusion prevents potential complications such as heart failure or arrhythmias.
