Key result
Zero-fluoroscopy cryoballoon ablation safely achieves PVI in a dextrocardia patient who remains asymptomatic at 1 year.
Why the study?

Is zero-fluoroscopy cryoballoon ablation feasible and safe in a patient with dextrocardia and paroxysmal atrial fibrillation?
Zero-fluoroscopy cryoballoon ablation is feasible and safe for treating paroxysmal atrial fibrillation in patients with complex congenital anatomy such as dextrocardia.
Supports feasibility of zero-fluoroscopy cryoballoon ablation in dextrocardia; leaves open generalizability and safety in larger cohorts.
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.

Yin et al. (2026) conducted a case report in Paroxysmal atrial fibrillation with dextrocardia (n=1). Zero-fluoroscopy cryoballoon ablation was evaluated on Pulmonary vein isolation and clinical status at 1-year follow-up. Zero-fluoroscopy cryoballoon ablation successfully isolated all four pulmonary veins without complications in a patient with dextrocardia, who remained asymptomatic at 1 year.
