Key result
Following radiofrequency catheter ablation, recurrence rates were 16.1% for AF, 5.8% for AFL, 5.7% for VT, 4.9% for WPW, and 2.0% for PSVT over an average 4.3-year follow-up.
Why the study?
Recurrence and complication rates after radiofrequency catheter ablation across various arrhythmias needed to be determined at a nationwide level.
Does the type of arrhythmia treated with radiofrequency catheter ablation affect the risk of recurrence and complications?

Does the type of arrhythmia treated with radiofrequency catheter ablation affect the risk of recurrence and complications?
This nationwide observational study demonstrates that complication and recurrence profiles after radiofrequency catheter ablation differ significantly depending on the underlying arrhythmia, with AF and AFL carrying higher risks for complications like pericardial effusion, stroke, and pacemaker implantation compared to PSVT.
Lin et al. (2019) conducted an observational in Arrhythmias (PSVT, WPW, AFL, AF, VT) (n=19,475). Radiofrequency catheter ablation (RFCA) vs. Comparison among arrhythmia types (PSVT as reference) was evaluated on Perioperative complications (pericardial effusion and new-onset stroke), RFCA recurrence and long-term outcomes (high-grade AVB and pacemaker implantation). Following radiofrequency catheter ablation, recurrence rates were 16.1% for AF, 5.8% for AFL, 5.7% for VT, 4.9% for WPW, and 2.0% for PSVT over an average 4.3-year follow-up.
