Abstract：Objective To explore the therapeutic effect of video-assisted thoracoscopic atrial appendage resection on recurrent atrial tachycardia originating from atrial appendage after radiofrequency catheter ablation.Method Between April 2021 and March 2024.8 cases of children with atrial tachycardia originating from the atrial appendage who underwent thoracoscopic atrial appendectomy at Shanghai Children's Medical Center were reviewed.All the cases were recurrent after radiofrequency ablation,including 5 males and 3 females,aged 7-10 years,body weight 19-46 kg.5 cases originated from left atrial appendage and 3 cases originated from right atrial appendage.Result The preoperative echocardiography measured the left ventricular ejection fraction(LVEF)was(40.18±12.27)％,left atrial diameter(LAD)was(2.88±0.48)cm and left ventricular end-diastolic dimension(LVEDD)was(5.25±0.74)cm;the cardiothoracic ratio was(0.63±0.07)and the N-terminal pro-B-type natriuretic peptide(NT-proBNP)was(4351.00±2718.00)pg/ml.All the patients underwent video-assisted thoracoscopic atrial appendage resection and immediately turned to sinus rhythm without recurrence.Postoperative echocardiography measured the LVEF was(58.88±9.81)％,LAD was(2.35±0.29)cm and the LVEDD was(4.46±0.82)cm;the cardiothoracic ratio was(0.53±0.06)and the NT-proBNP was(834.00±397.00)pg/ml.During the outpatient follow-up ranging from 6 months to 3 years,there were no deaths,no recurrences and no severe complications observed.Conclusion For pediatric intractable atrial tachycardia originating from the atrial appendage,VATS appendectomy is an ideal surgical approach.VATS appendectomy through an electric cutting and suturing device is safe,effective and more convenient.
