Introduction
Late gadolinium enhancement (LGE) by cardiac magnetic resonance (CMR) has been used to accurately identify and quantify ventricular myocardial fibrosis. Intramyocardial and/or subepicardial LGE, unrelated to the distribution of coronary arteries, is indicative of myocarditis and/or cardiomyopathy. Nonetheless, several studies showed that the presence and amount of myocardial fibrosis is important for ventricular arrhythmias. Frontal planar QRS/T angle provides information about the electrical heterogeneity of the ventricles during repolarization. In this context, the aim of the study was to investigate the relationship between the presence of non-ischemic myocardial fibrosis and repolarization heterogeneity of the ventricles in patients with non-specific myocarditis.
Material and Methods
A total of 68 patients, in whom CRM was performed due to the suspicion of non-specific myocarditis and/or cardiomyopathy, were retrospectively analyzed. Patients with ischemic cardiomyopathy, hypertrophic cardiomyopathy and congenital heart disease were excluded. Subsequently, patients were divided into two groups; LGE (+) and LGE (-). LGE (+) group was consisted of 36 patients and LGE (-) group was consisted of 32 patients. The absolute difference between the frontal QRS wave axis and T-wave axis was defined as frontal planar QRS/T angle.
