Cryoballoon Catheter Ablation in Atrial Fibrillation

Figure 1

Cryoballoon catheter placement for pulmonary vein isolation with fluoroscopic A. Fluoroscopic appearance (30° left anterior oblique view) of the cryoballoon inflated in a left superior pulmonary vein. The guidewire was advanced in a pulmonary vein branch, and the occlusion is confirmed by the absence of flow during contrast injection in the vein. The circular mapping catheter is placed at the ostium of the right superior pulmonary vein. A multipolar catheter in the coronary sinus and an intracardiac echocardiography catheter in the mid-right atrium are visible.
