[Modified Warden procedure for correction of right superior vena cava drainage in the left atrium].

A newborn with situs solitus, normally related great arteries and intact atrial septum, underwent surgical repair at our institution for anomalous drainage of the right superior vena cava in the left atrium at the level of the right superior pulmonary veins. This rare cyanotic congenital cardiac malformation is herein described with special regard to its anatomical and diagnostic features. A novel surgical approach for achieving correction is also described.
