Remote navigation guided ablation of incessant atrial tachycardia in a patient with restricted venous access.
We report a case of a 45-year-old man with incessant supraventricular tachycardia (SVT) in the setting of intrahepatic inferior vena cava thrombus and a left upper extremity arteriovenous fistula. A diagnostic electrophysiology study (EPS) was performed via the right internal jugular and right subclavian veins. After confirming the mechanism of SVT was atrial tachycardia (AT), mapping, and successful ablation was performed using remote catheter navigation. This case demonstrates that remote navigation can facilitate the therapy of complex arrhythmias in challenging clinical situations.
