Successful cryoablation of atrial fibrilation from jugular approach in patient with interrupted inferior vena cava and azygos continuation.

We herein report a successful cryoablation of paroxysmal atrial fibrilation via right jugular vein in patient with interrupted inferior vena cava. We preferred cryoablation instead of radiofrequency ablation in the treatment of our patient. For stronger support in aiming the Brockenbrough needle toward to the septum, we manuallly curved the needle with a 120⁰ angle about 6 cm proximal to the tip. After successful septostomy, we performed balloon dilatation in the septal puncture zone to facilitate passage. Cryoablation has the theoretical advantage particularly in the challenging anatomies in which it eliminates the need for point-by-point ablation around the pulmonary vein.
