ABSTRACT

Sinus venosus atrial septal defects present a wide variety of anatomical features and are frequently associated with partial anomalous pulmonary venous drainage of one or more right pulmonary veins. Surgical correction used to be the standard treatment. In recent times, transcatheter correction of superior sinus venosus atrial septal defects has come into vogue. The transcatheter closure of these defects with covered stents at a tertiary care centre in Oman between 2018 and 2023 is reported.

ABSTRACT

This review provides an update on the morphology of the sinus venosus defect. It was earlier believed that a 'common wall' separated the right pulmonary veins from the superior caval vein. In the sinus venosus defects, this wall was absent. Current evidence shows that the superior rim of the oval fossa, rather than forming a second septum or representing a common wall, is an infolding between the walls of the caval veins and the right pulmonary veins. The sinus venosus defect is caused by the anomalous connection of one or more pulmonary veins to a systemic vein. However, the pulmonary vein(s) retain their left atrial connections, leading to a veno-venous bridge that allows interatrial shunting outside the oval fossa. True atrial septal defects are located within the oval fossa or in the anteo-inferior buttress, while sinus venosus defects, ostium defects and coronary sinus defects are morphologically distinct from them.

ABSTRACT

Major aortopulmonary collateral arteries can influence the postoperative course of arterial switch operation, with heart failure being the common clinical presentation. A relatively rare presentation of an aortopulmonary collateral artery in the form of persistent postoperative pulmonary hemorrhage was encountered after an uneventful arterial switch operation in a neonate with transposition of the great arteries, intact interventricular septum, and situs inversus totalis. The aortopulmonary collateral artery was coil embolized with a successful outcome.
