Regarding the risk of atrial arrhythmias in arrhythmogenic right ventricular cardiomyopathy patients undergoing ventricular tachycardia ablation
Sir, we read Zado’s study1 with great interest. The objective of this study was to determine the type, prevalence, outcome, and risk correlates of atrial arrhythmias (AAs) in arrhythmogenic right ventricular cardiomyopathy (ARVC) in patients undergoing ventricular tachycardia (VT) ablation. The risk score for typical atrial flutter was determined from univariate logistic regression analysis, then they found that the risk score for typical flutter included age >40 years, ≥moderate right ventricular dysfunction, ≥moderate tricuspid regurgitation, ≥moderate right atrial dilation, and right ventricular volume >250 cc, with score >4 identifying 50% prevalence of typical flutter.
