These patients underwent follow\u2010up TTE at 12 months after the RFCA, and were categorized into two groups based on the improvement (defined as at least one\u2010grade improvement of TR) and non\u2010improvement of TR: IM group and Non\u2010IM group, respectively. We compared the patient characteristics, ablation procedures, and recurrences after the RFCA between the two groups. In addition, we examined the major event (defined as admission for heart failure or all\u2010cause death) more than 12 months after the RFCA.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>IM group consisted of 90 patients (64%). A multivariate analysis revealed that age &lt;71 years old and absence of late recurrence (LR, defined as recurrence of atrial tachyarrhythmia between 3 and 12 months after the RFCA) were independently associated with the improvement of TR after the RFCA.
