Introduction
The
duplication of the inferior vena cava (IVC) is a rare anatomical
variation occurs during embryological development of the IVC[1]. This
anomaly interrupts the IVC, which renders the ablation of atrial
fibrillation (AF) impossible with the standard approach via IVC to left
atrium. To address the technical difficulty, we adopted the surgical
bipolar radiofrequency ablation
(endoscopic maze procedure) through the left chest cavity in patients
with an interrupted IVC.
