[The angiographic diagnosis of the connection of the persistent left vena cava superior to the left atrium by the absence of the roof of the coronary sinus in a child with a Holmes' heart].

We describe a patient with angiographic findings of a left superior persistent vena cava draining in the left atrium with absence of the coronary sinus' roof and coexisting with Holmes' heart. The diagnosis can be made by selective angiography in the left atrium, pulmonary vein or at the left superior vena cava. We want to emphasize the importance of knowing this sort of anomaly before surgical treatment.
