Caval vein obstruction resulting in right to left shunt and desaturation post-endocardial pacing implantation in a 3-year old: a case report.

ABSTRACT:

Background

Superior caval vein obstruction is a rare complication of endocardial pacing lead implantation that can result in a right to left shunt.

Case summary

A 3-year-old child with type 2 Brugada syndrome presented with mild cyanosis post-endocardial pacing implantation due to evolutionary right superior caval vein obstruction. This obstruction resulted in a right to left shunt across a previously unrecognized patent levo-atrial cardinal vein associated with partial anomalous pulmonary venous drainage. The patient underwent endocardial pacing explantation, balloon dilation and stenting of the right superior caval vein, banding of the levo-atrial cardinal vein to left upper pulmonary vein venous channel, and implantation of an epicardial pacing system.
