Cinematic rendering of the coronary-pulmonary arterial fistula

Coronary-pulmonary arterial fistula is a rare coronary artery abnormality disease, which refers to a coronary fistula that terminates at the pulmonary artery. Coronary-pulmonary fistulas are much less common in children than in adults, and the small fistulas are easily missed. We report the case of a 9-year-old girl who presented with coronary-pulmonary arterial fistula. She underwent multimodal imaging, including chest X-ray, echocardiography, computed tomography with 3-dimensional cinematic rendering. We found that the cinematic rendering images clearly showed the small-caliber fistulous connections. The combination of CT and echocardiography can effectively help doctors understand the anatomical details and hemodynamic information.
