Crescenzi C, Zorzi A, Vessella T, et al. - A multicenter study was conducted to investigate which ventricular arrhythmias (VA) characteristics predicted cardiac magnetic resonance (CMR) abnormalities. In this study, 251 consecutive competitive athletes were included (74% males, median age 25 [17‐39] years) who had undergone CMR for assessment of VA. Athletes with >100 premature ventricular beats/24 h or ≥ 1 repetitive VA (couplets, triplets, or nonsustained ventricular tachycardia) on 12‐lead 24‐hour ambulatory ECG monitoring and negative family history, ECG, and echocardiogram were included. The results demonstrated that the simple characteristics such as number and morphology of premature ventricular beats on 12‐lead 24‐hour ambulatory ECG monitoring and response to exercise testing predicted the presence of concealed myocardial abnormalities on CMR in athletes with apparently idiopathic VA. Moreover, these outcomes may help cost‐effective CMR prescription.
