Duplicated inferior cava (IVC) is an anomaly we rarely encounter during electrophysiologic procedures. We report a case with duplicated IVC who developed thrombosis of the left IVC following an electrophysiologic procedure, which resulted in an asymptomatic pulmonary embolism. It is speculated that several catheters placed in the torturous route through the left IVC caused either endothelial damage to the vessel wall, or hemostasis in the relatively narrow portion of the vessel, resulting in thrombus formation. Since the prevalence and characteristics of thrombo-embolic complications during electrophysiologic procedures in patients with a duplicated IVC remain unknown, we believe this case should be reported.
