Key result
AF ablation results in right hemidiaphragm paralysis in one patient, improving with conservative management.
Why the study?
Phrenic nerve injury is a rare complication of AF ablation that is often underrecognized as a cause of post-procedural dyspnea.
Case Report (n=1)
Phrenic nerve injury should be considered as a potential cause of new exertional dyspnea following atrial fibrillation ablation to prevent unnecessary interventions for presumed heart failure.
No takes yet. Share an insight, caveat, or question.
Consider phrenic nerve injury in new dyspnea after AF ablation; this case extends awareness but leaves open incidence and screening needs.
Harikrishnan et al. (2026) conducted a case report in Atrial fibrillation (n=1). Atrial fibrillation ablation was evaluated on Phrenic nerve injury. Atrial fibrillation ablation resulted in right hemidiaphragm paralysis in 1 80-year-old woman, which gradually improved with conservative management and pulmonary rehabilitation.
