Polysplenia with left ventricular hypoplasia and partial anomalous pulmonary venous connection.

A case is reported of left ventricular hypoplasia associated with anisosplenia. Even though congenital heart malformations are frequently found in cases of splenic anomalies, the association of polysplenia with hypoplastic left heart syndrome is extremely rare. The existence in addition of partial anomalous pulmonary venous connection of the right pulmonary veins to the right atrium, gave us the possibility of study the different changes in pulmonary arteries wall thickness in both lungs.
