摘要: Objectives The purpose of this study was to correlate 3-dimensional distribution epicardial fat on computed tomography (CT) with electroanatomical (EA) voltage maps obtained during percutaneous mapping in order determine the thickness cut-off that results attenuation and establish normal ventricular criteria absence fat. Background Epicardial can mimic scar tissue when is performed, as both result low voltage. Cardiac CT differentiate from or muscle basis their distinct attenuations. Methods Transcutaneous performed a consecutive series 14 patients. A cardiac before procedure image generated registered EA map. Results In patients without cardiomyopathy (n = 8), ≥1.5 mV best correlated ≥2.8 mm resulted separated ( 10 were ineffective. Conclusions identifies mapping, which important ablation.
