Introduction: We wanted to determine the acute and long-term effectiveness and safety of radiofrequency catheter ablation in Chinese pediatric patients with arrhythmias. Methods: We gathered clinical data from pediatric patients who received RFCA in several large medical centers in China between 2000 and 2019. The bulk of supraventricular tachycardia are caused by atrioventricular tachycardia and atrioventricular nodal reentry tachycardia. 94. 4%/92. 2%, AVRT 99. 8%/92. 2%, PVC 97. 2%/92. 2%, and VT 88. 13%/75. 2% were the overall success rate of RFCA. 96. 4%/92. 2%, 96. 4%/92. 2%, 89. 6%/92. 2%, 92. 2%, 97. 2%/92. 2%, 96. 2%/92. 2%, 96. 2%/92. Conclusions: This present study shows that RFCA is safe and efficient in the treatment of arrhythmias in Chinese pediatric patients with a 90 percent success rate, low recurrence rate, and greatly reduces the risk of complications. The success rate of left-sided pathway ablation is marginally higher than that of the right-sided pathway. Children of various ages do not have a difference in the success rate of RFCA.

We investigated the safety of BRA for sinus rhythm restoration in patients with AF who are undergoing CABG. Methods: Patients with permanent or paroxysmal AF underwent BRA treatment with CABG in our institution from May 2014 to June 2020. We found that group II patients had higher sinus rhythm recovery rates after BRA with CABG than group I patients. Overall mortality in group II patients was much lower than in patients in group I. According to Kaplan u2013Meier's report, the survival rate in group II was much higher in group II than in group I. The Cox hazards survival regression ratio was significantly different among groups in the 95% confidence interval. AF with CABG and permanent AF were found as predictors of post-brace recurrent AF.
