Is cardiac magnetic resonance of additional help in premature ventricular contraction work-up?

Abstract Background Premature ventricular contractions (PVCs) are common in routine medical practice. PVCs commonly asymptomatic but can also result palpitations, dyspnea, presyncope or PVC-induced cardiomyopathy that may lead to sudden death. Cardiovascular magnetic resonance (CMR) provides morphological, functional, and tissue characterization a single setting. CMR imaging proved reliably identify fibrotic lesions and, hence, has developed into valuable tool for etiological orientation patients with PVCs. Objectives The aims of this study were: 1) evaluate which arrythmia (VA) characteristics predicted abnormalities 2) the diagnostic yield impact management CMR-based versus non-CMR-based referred Methods This monocentric retrospective was conducted imaging. Their baseline interview characteristics, physical examination, surface electrocardiogram (ECG) analysis, ambulatory monitoring, echocardiography treadmill exercise test data were collected when they available. (1,5 T 3.0 T) protocol included cine late gadolinium enhancement (LGE) using standard cardiac geometries. Results We analyzed 168 (65% males, mean age 54.2±16.8 years) our center over two-year period. reported abnormal findings 73 (43.5%) diagnosis structural heart disease (SHD) 46 (27.4%). Left-ventricular gadolinium-enhancement documented 43 CMR. Using multivariate (p=0.026), sustained tachycardia (p=0.002) presence on (p<0.001) significantly Compared imaging, had yield, by modifying presumed finding requiring follow-up (43.5%). Conclusions Age, strongest predictors positive results. Although is generally used first intention PVCs, showed robust indication. Funding Acknowledgement Type funding sources: None.
