    Intracardiac echocardiography (ICE) enhances radiofrequency catheter ablation (RFCA) outcomes for atrial fibrillation by improving procedural metrics.

  • 2

    The study involved 167 patients, with 102 after propensity score matching, comparing ICE and non-ICE groups.

  • 3

    High force-over-time (FOT) counts in specific segments were linked to increased recurrence rates after RFCA.

  • 4

    ICE-guided procedures showed improved recurrence rates, suggesting that benefits may stem from better FOT management.

  • 5

    Factors influencing ablation and procedure times included eGFR, FOT counts, and presence of cardiomyopathy.
