• Occurrence and Frequency of Arrhythmias in Hypertrophic Cardiomyopathy in Relation to Delayed Enhancement on Cardiovascular Magnetic Resonance A. Selcuk Adabag, Barry J. Maron, Evan Appelbaum, Caitlin J. Harrigan, Jacqueline L. Buros, C. Michael Gibson, John R. Lesser, Constance A. Hanna, James E. Udelson, Warren J. Manning, Martin S. Maron We studied prevalence and frequency of arrhythmias on 24-h ambulatory electrocardiogram with regard to delayed enhancement (DE) on contrast-enhanced cardiovascular magnetic resonance (CMR) in 177 hypertrophic cardiomyopathy (HCM) patients. Premature ventricular contractions (PVCs), couplets, and nonsustained ventricular tachycardia (NSVT) were more common (PVCs: 89% vs. 72%; couplets: 40% vs. 17%; NSVT: 28% vs. 4%; p < 0.0001 to 0.007) and more frequent (all p < 0.0001) in patients with DE than in those without DE. Furthermore, DE was an independent predictor of NSVT (relative risk 7.3, 95% confidence interval 2.6 to 20.4; p < 0.0001). These findings suggest that CMR identifies HCM patients with increased susceptibility to ventricular tachyarrhythmias.
