Complex electrophysiology intervention in a patient with an inferior vena cava filter

Catheter ablation is currently a routine clinical method for the treatment of heart rhythm disorders. The presence of a filter in the lumen of the inferior vena cava represents a mechanical obstruction that may complicate or contraindicate the procedure. Still, there is not enough information available on this topic and there is no research data on the catheter ablation of complex left atrial arrhythmias with a transseptal puncture in the presence of an inferior vena cava filter. Our case report represents a successful complex electrophysiology intervention in both the left and right atria with femoral venous access in a patient with an inferior vena cava filter.
