Resumen de The Chiari network: an anatomical variation or a risk factor?

Elena Félix Domínguez, Blanca Mompeó Corredera

• We report an association between a Chiari network and an abnormally long coronary sinus. The network, at the Eustachian valve and a morphologically similar network in the Thebesian valve, was also associated with a permeable foramen ovale. We review the embryological basis, associated anomalies, pathological conditions and clinical relevance.
