Ectopic atrial tachycardia originating from right atrial appendage aneurysms in children: Three case reports
نویسندگان
چکیده
Introduction Ectopic atrial tachycardia occurs at a rate of 5%–20% among children with supraventricular tachycardia. Atrial appendages are the most frequent focus in children, differing from the situation in adults. However, ectopic atrial tachycardia originating from aneurysms of the right atrial appendage is very rare and in fact has not yet been clearly defined. We describe 3 cases of children with ectopic atrial tachycardia resulting from right atrial appendage aneurysms that proved refractory to radiofrequency catheter ablation. All 3 children were treated surgically. Written consent from the legal guardians of the patients was received for publication of the details of these cases.

Epicardial Ablation of Focal Atrial Tachycardia Arising From Left Atrial Appendage in Children
Focal left atrial tachycardia (FLAT) although a common cause of supraventricular tachycardia(SVT) among children, the one's arising from left atrial appendage (LAA) present a unique challenge for successful ablation because of anatomical location. We present two children with FLAT arising from the epicardial LAA, successfully mapped and ablated through percutaneuous epicardial approach.
متن کاملAblation of cardiac tissues by an electrode catheter technique for treatment of ectopic supraventricular tachycardia in adults.
Five patients with chronic or recurrent ectopic supraventricular tachycardias unresponsive to drugs underwent programmed stimulation, endocardial mapping, and attempted catheter ablation of the arrhythmia focus. For attempted ablation, an intracardiac electrode catheter was positioned near the exit point of the tachycardia and served as the cathode while a chest wall patch served as the anode. ...
متن کاملCongenital aneurysm of the right atrial appendage in a newborn: a rare anomaly.
Aneurysm of the atrial appendages is an uncommon condition, with few cases described in the literature. These aneurysms are classified into 2 groups: congenital and acquired (mainly secondary to trauma). Those affecting the left atrial appendage, which were first described by Semans and Taussing in 1938, usually manifest in the third and fourth decade of life as tachyarrhythmia refractory to ph...
متن کاملA case of successful termination of an atrial tachycardia ablated from the pulmonary artery during rapid ventricular pacing
Figure 1 a: Surface ECG recorded during atrial tachycardia (AT). P-wave polarity during the AT was positive in leads II, III, aVF, and V1 and negative in leads I and aVL. The AT cycle length was 510 ms. b: Findings from ablation in the pulmonary artery. The earliest local atrial potential preceded P-wave onset by 52 ms. Ablation from that site temporarily accelerated the AT rate (116 to 159 bpm...
متن کاملSuccessful radiofrequency catheter ablation therapy of an adolescent with atrial ectopic tachycardia.
Atrial ectopic tachycardia is an incessant supraventricular tachycardia and is frequently refractory to medical treatment. Because it can cause tachycardia-induced cardiomyopathy, early diagnosis and treatment is important. We present a 16-year-old boy who was diagnosed as atrial ectopic tachycardia. The tachycardia, originating from the lower region of the right atrium along the crista termina...
