Percutaneous transhepatic access for catheter ablation of A patient with heterotaxy syndrome complicated with atrial fibrillation ：a case report

Atrial fibrillation (AF) is one of the most common arrhythmia, and radiofrequence catheter ablation has become the most effective treatment method.The inferior vena cava(IVC)is a common approach for radiofrequency ablation of atrial fibrillation. In some cases, this approach cannot be used, such as chronic venous occlusions, surgical ligation of the IVC and heterotaxy syndrome. In patients without femoral vein access, use of the hepatic vein for PVI is a viable alternative for invasive EP procedures.
