Key result
Surgical correction of a left superior caval vein emptying into the left atrium by tunnelling it towards the right atrium resulted in an asymptomatic narrowing inside the baffle 6 months later.
Case Report (n=1)
Surgical correction of a single left superior caval vein draining into the left atrium by intra-atrial baffle can be complicated by baffle narrowing at 6 months follow-up.
A 15-month-old boy presented with asymptomatic hypoxaemia due to right-to-left venous shunting via a left superior caval vein emptying into the left atrium, in absence of right superior caval vein. The diagnosis, suspected by contrast echocardiography, was confirmed by computed tomography and angiography. The child underwent surgical correction of the systemic anomalous return by tunnelling the left superior caval vein towards the right atrium. An asymptomatic narrowing inside the intra-atrial baffle developed 6 months later.

Schleich et al. (2006) conducted a case report in Systemic venous drainage via a single left superior caval vein into the left atrium (n=1). Surgical correction by tunnelling the left superior caval vein towards the right atrium was evaluated on Development of narrowing inside the intra-atrial baffle. Surgical correction of a left superior caval vein emptying into the left atrium by tunnelling it towards the right atrium resulted in an asymptomatic narrowing inside the baffle 6 months later.
