Leipzig study finds catheter ablation stabilizes heart rhythm but not quality of life

A multi-center study presented at the ESC Congress in Munich and published in ‘The Lancet’ suggests that while catheter ablation effectively stabilizes heart rhythm in patients with atrial fibrillation, it does not significantly improve their perceived quality of life compared to a sham procedure.

The PVI-SHAM-AF study, led by the University of Leipzig and involving nine clinics across Germany and Poland, monitored 262 patients. The results showed a clear discrepancy between clinical success and patient well-being. In the ablation group, 73 percent of patients remained free of atrial fibrillation, compared to only 52 percent in the sham group.

Despite this objective success in reducing arrhythmia recurrence, the subjective quality of life for patients did not show a significantly higher improvement than those receiving the placebo intervention. Catheter ablation remains a standard procedure used to interrupt irregular electrical signals in the heart, but these findings raise new questions regarding its impact on overall patient well-being.
