Reply to the Editor — Risk of atrial arrhythmias in arrhythmogenic right ventricular cardiomyopathy patients undergoing ventricular tachycardia ablation

In reply to the response of Drs Cheng and Zhang to our paper,1 we note that despite arrhythmogenic right ventricular cardiomyopathy being a relatively uncommon cardiomyopathy, we uniquely report on a large clinical experience with long-term follow-up after ventricular tachycardia ablation and confirm a high incidence of atrial flutter and the effectiveness and low risk of catheter ablation of atrial flutter. We also readily acknowledge that a risk score for predicting a clinical outcome is strengthened by a large data set, and we noted as a limitation that our risk score is based on a relatively small number of patients at a single center and should be considered hypothesis generating and that additional multicenter investigation is needed to confirm that the score has utility.
