BACKGROUND Studies of ventricular fibrillation (VF) in small mammals have revealed localized sustained stationary reentry. However, studies in large mammals with surface mapping techniques have demonstrated only relatively short-lived rotors. The purpose of this study was to identify whether sustained high-frequency activation with low beat-to-beat(More)
BACKGROUND Percutaneous approaches for radiofrequency ablation of ventricular tachycardia (VT) in the left ventricle are typically transarterial retro-aortic, antegrade transmitral via an interatrial septal puncture, or epicardial. However, all 3 approaches may be contraindicated in certain cases. We describe 2 cases of VT ablation in which aortic and(More)
BACKGROUND Radiofrequency (RF) ablation causes thermal mediated irreversible myocardial necrosis. This study aimed to (i) characterize the thermal characteristics of RF ablation lesions with high spatial resolution using a thermochromic liquid crystal (TLC) myocardial phantom; and (ii) compare the thermochromic lesions with in vivo and in vitro ablation(More)
