Abstract

This report describes a case of isthmus-dependent atrial flutter ablation by the femoral approach in a 54-year-old woman with a previously unknown absence of the inferior vena cava (IVC) and dual chamber pacemaker. Despite looping of the catheters, ablation and termination of atrial flutter were performed successfully without function alteration of the pacemaker leads.  This is the first report of an inferior-to-superior approach for ablation of atrial flutter in the absence of the perihepatic IVC with the presence of chronic indwelling leads in the area targeted for radiofrequency. 

Keywords:
