“…When sustained atrial flutter occurs after HT, radiofrequency ablation is a viable option after primary etiologies such as acute rejection, LV dysfunction, and cardiac ischemia have been excluded. The altered anatomy of the transplanted heart often makes catheter placement challenging for ablation of right atrial isthmus flutter . Mitral isthmus flutter can be ablated using standard techniques used in the non‐HT context.…”

“…Bi-atrial anastomosis 2 especially seems to predispose the atrium to various re-entrant arrhythmias. The surgical suture line between the donor and recipient atria creates the central anatomic obstacle, 3 however, re-entrant tachycardia may spread from the donor atrium into the recipient atrium through bi-directional recipientdonor atrial conduction. 4,5 However, some arrhythmias may have a focal origin.…”

“…This finding is analogous to the proposed mechanism of supraventricular tachyarrhythmias in patients who have undergone extensive atrial surgery for congenital heart disease, such as some forms of the modified Fontan operation, and atrial switch procedures (Mustard or Senning operations) (1–5). In transplanted hearts, where there may be both right and left atrial suture lines, atrial flutter has been noted, mapped to the right atrium, and successfully treated with radiofrequency ablation (11–13). A comparison of patients who had a right atrial anastomosis to those who had bicaval anastomoses for heart Tx yielded a significantly higher incidence of atrial arrhythmias in the group that underwent right atrial anastomosis: only one patient in the bicaval anastomosis group (n = 30) had an atrial arrhythmia, whereas 12 patients in the right atrial anastomosis group (n = 30) had atrial arrhythmias during the follow‐up period (14).…”

Atrial arrhythmias have been reported after congenital heart surgery involving extensive atrial suture lines. Experimental studies involving bilateral lung transplantation (Tx) suggest that the left atrial suture lines predispose to atrial flutter. The overall incidence and type of arrhythmias after pediatric lung Tx have not previously been described and therefore the purpose of this study was to prospectively screen and describe arrhythmias in a subset of our lung transplant population. Over a 1-yr study period, all recipients of bilateral lung Tx were admitted to a full-disclosure telemetry unit. Single-lead electrocardiograms were recorded continuously and reviewed daily via a beat-by-beat analysis. A total of 314 patient days (range 9-93, median 43 days) were recorded from seven patients. The incidence of arrhythmias observed per total patient days included junctional escape rhythm (4.8%), non-sustained ventricular tachycardia (4.1%), accelerated junctional (2.5%), sinus bradycardia (2.2%), non-sustained supraventricular tachycardia (1.3%), ectopic atrial tachycardia (1.0%), sustained ventricular tachycardia (0.3%), junctional ectopic tachycardia (0.3%), and second degree heart block (0.3%). No patient had sustained supraventricular tachycardia, atrial flutter, atrial fibrillation, or complete heart block. Arrhythmias were treated in two patients. During the follow-up period, one patient received amiodarone for ventricular tachycardia (which was also noted and treated prior to transplant). We conclude that among pediatric lung transplant recipients admitted for their transplant surgery, arrhythmia is uncommon and rarely requires therapy.
