Abstract

The catheter ablation of supraventricular arrhythmias is generically performed via using a trans femoral venous approach through the inferior vena cava (IVC). However, this procedure becomes a subtle issue if there is a congenital or an acquired obstruction of the IVC. Here, we report a very particular case of slow pathway ablation for atrioventricular nodal reentrant tachycardia in a patient with an interrupted vena cava by virtue of the lower approach.
