Fluoroscopic Appearance of a Single-Wall Cryoballoon Breach During Pulmonary Vein Isolation.

Cryoballoon ablation therapy is increasingly used for pulmonary vein isolation. Its safety and efficacy profile is comparable to that of radiofrequency ablation therapy. Double-wall cryoballoon breaches have been described in published reports. This report presents a case of single-wall cryoballoon rupture captured under fluoroscopy, with no adverse effect on the patient. (Level of Difficulty: Intermediate.).
