A 68-year-old man with mirror-image dextrocardia and symptomatic, drug-refractory paroxysmal atrial fibrillation underwent zero-fluoroscopy cryoballoon ablation. Intracardiac echocardiography and 3D electroanatomic mapping were used to guide transseptal puncture, navigate the mirror-image anatomy, and confirm pulmonary vein occlusion. All four pulmonary veins were successfully isolated without complications. At 1-year follow-up, the patient remained asymptomatic without antiarrhythmic medication. This case demonstrates the feasibility and safety of a completely fluoroless cryoballoon ablation strategy in a patient with dextrocardia, effectively overcoming the challenges of complex congenital cardiac anatomy.
