Characteristics of intramural scar in patients with nonischemic cardiomyopathy and relation to intramural ventricular arrhythmias.
BACKGROUND Ventricular arrhythmias have been described to originate from intramural locations. Intramural scar can be assessed by delayed-enhanced MRI, but MRIs cannot be performed on every patient. The objective of this study was to assess the value of voltage mapping to detect MRI-defined intramural scar and to correlate the scar with ventricular arrhythmias. METHODS AND RESULTS In 15 conse...
متن کاملAlcoholic cardiomyopathy and ventricular arrhythmias.
We read with interest the article by Piano et al1 (May 2002) about alcoholic cardiomyopathy (ACM), with a complete clinical and physiopathologic overview on this leading cause of nonischemic heart failure. We agree with all the comments and conclusion of the author, and we thank Dr. Piano for the several citations of our work on this topic published in 2000.2 We would like to add a short commen...
متن کاملVentricular arrhythmias in idiopathic dilated cardiomyopathy.
Twenty four hour ambulatory electrocardiograms were recorded in 60 patients with idiopathic dilated cardiomyopathy. The diagnosis was based on clinical, laboratory, and cardiac catheterisation findings. All patients had a left ventricular ejection fraction less than 0.55; in 39 it was less than 0.40. Ventricular extrasystoles were evident in all patients: they were rare in 11 (18%), moderately ...
متن کاملConduction remodeling in human end-stage nonischemic left ventricular cardiomyopathy.
BACKGROUND Several arrhythmogenic mechanisms have been inferred from animal heart failure models. However, the translation of these hypotheses is difficult because of the lack of functional human data. We aimed to investigate the electrophysiological substrate for arrhythmia in human end-stage nonischemic cardiomyopathy. METHODS AND RESULTS We optically mapped the coronary-perfused left ventr...
متن کاملECG criteria to identify epicardial ventricular tachycardia in nonischemic cardiomyopathy.
BACKGROUND ECG criteria identifying epicardial (EPI) origin for ventricular tachycardia (VT) in nonischemic cardiomyopathy have not been determined. Endocardial (ENDO) and EPI basal left ventricle fibrosis characterizes the VT substrate. METHODS AND RESULTS We assessed the QRS from 102 basal-superior/lateral EPI and 67 comparable ENDO pace maps in 14 patients with nonischemic cardiomyopathy. ...
