Key result
Catheter ablation of atrial flutter in patients with severe pulmonary arterial hypertension achieved an 86% acute success rate and significantly reduced systolic pulmonary artery pressure (P=0.004).

Does catheter ablation of atrial flutter improve outcomes and hemodynamics in patients with severe pulmonary arterial hypertension?
Catheter ablation of atrial flutter in patients with severe pulmonary arterial hypertension is feasible and associated with significant reductions in pulmonary pressures and BNP, though overall 1-year mortality in this population remains high.
Bradfield et al. (2012) conducted an observational in Severe pulmonary arterial hypertension and atrial flutter (n=12). Radiofrequency catheter ablation was evaluated on Acute procedural success. Catheter ablation of atrial flutter in patients with severe pulmonary arterial hypertension achieved an 86% acute success rate and significantly reduced systolic pulmonary artery pressure (P=0.004).
