Circumferential pulmonary vein ablation of atrial fibrillation via superior vena cava approach in a patient with interruption of the inferior vena cava.

Interruption of the inferior vena cava (IVC) is a very rare congenital abnormality. Such patients have many difficulties during ablation procedures. We report a case of successful ablation of paroxysmal atrial fibrillation using the superior vena cava in a patient with interruption of the IVC.
