“…Oxidation-reduction reaction stress and the activation of the neurohumoral system also play a role. Incessant ATs can lead to TIC in both adults and children, accounting for 5% of all TIC cases in adults and 14% in children [ 9 ]. Appendage tachycardia is characterized by persistence and refractory antiarrhythmic therapy and accounts for 25–50% of all Ats cases, of which 25% develop cardiomyopathy.…”

Background Atrial tachycardia (AT) originating from the left atrial appendage (LAA) is uncommon and the most difficult arrhythmia to eliminate. Therefore, we present the case of a 5-year-old girl with tachycardia-induced cardiomyopathy (TIC) caused by AT originating from the LAA and successfully treated with RFCA associated to left atrial appendectomy. With resolution of AT, we observed a progressive improvement of LV function. The effectiveness and safety of this combination therapy were evaluated over a one-month follow-up period. Case presentation A 5 -year-old female was evaluated for three days of incessant cough and a syncopal episode. Surface echocardiography and 24-hour monitoring showed that the infant had persistent atrial tachycardia. Echocardiography revealed an enlarged tele diastolic diameter (46.1 mm) and malfunctioning (EF 28.53%) left ventricle. The location of the lesion at the apex of the LAA was further confirmed by electrophysiological study and RFCA. After RFCA, the infant’s ECG monitor showed that sinus rhythm was maintained for up to 22 h. Subsequently, atrial tachycardia recurred and sinus rhythm disappeared. Finally, atrial appendectomy was performed and sinus rhythm returned to normal. Conclusions The heart function of the infant improved and sinus rhythm was maintained, further demonstrating the safety and effectiveness of combined treatment with RFCA and atrial appendectomy after electrophysiological localization of AT from LAA to TIC.

“…TCM is a form of reversible myocardial dysfunction caused by chronic arrhythmias, which is characterized by ventricular systolic dysfunction, dilatation, and heart failure that can be reversed with normalization of heart rate (3,8) . Incessant ATs can lead to TCM in both adults and children, accounting for 5% of all TCM cases in adults and 14% in children (9) . Appendage tachycardias were the most preferential site for ATs and had the feature of being incessant and refractory to antiarrhythmic treatment.…”

Background: Atrial tachycardia (AT) originating from the left atrial appendage (LAA) is uncommon and the most difficult arrhythmia to eliminate. Herein, we present the case of a 5-year-old girl with tachycardia-induced cardiomyopathy (TCM) caused by ATs originating from the LAA who was successfully treated with a combination of electrophysiological mapping, radiofrequency catheter ablation (RFCA), and atrial appendectomy. The effectiveness and safety of this combination therapy were evaluated through a 1-month follow-up period. Case presentation: A 5-year-old female patient presented with cough for 3 days and syncope for 1 day. Surface echocardiography and 24-hour monitoring showed that the patient had persistent atrial tachycardia. Echocardiography revealed that the patient had an enlarged left ventricular diastolic dysfunction (46.1 mm) and reduced left ventricular ejection fraction (28.53%). The location of the lesion at the apex of the LAA was further confirmed by an electrophysiological study and RFCA. After RFCA, electrocardiographic monitoring showed a sinus rhythm with occasional paroxysmal atrial tachycardia. Finally, atrial appendectomy was performed, and the sinus rhythm returned to normal. Conclusions. The heart function of the child improved and sinus rhythm persisted, proving the safety and effectiveness of the combined therapy of electrophysiological mapping, RFCA, and atrial appendectomy on TCM caused by ATs originating from the LAA.
