A Moving Target for Catheter Ablation of Ventricular Tachycardia: Ablation of Scar or Arrhythmia?
SEE PAGE 2872 C atheter ablation of ventricular tachycardia (VT) reduces recurrent VT across multiple clinical settings, from electrical storm to pre-emptive therapy after a first occurrence of VT (1). Approaches for ablation include targeting the arrhythmia using electrophysiological approaches (entrainment mapping, pacemapping, and electroanatomic mapping) and substrate modification to reduce...
متن کاملA systematic review of the effectiveness of catheter ablation NavX mapping system for treatment of the cardiac arrhythmia
Background: Catheter ablation is widely used for treatment of atrial fibrillation. The use of fluoroscopic and non-fluoroscopic mapping systems in catheter ablation is common. This study conducted to investigate the safety and effectiveness of Navx non-fluoroscopic mapping system. Methods : In this study, the appropriate electronic databases including Cochrane Library and Ovid Medline searc...
متن کاملCatheter ablation for ventricular tachycardia.
Sustained ventricular tachycardia (VT) is an important cause of morbidity and sudden death in patients with heart disease.1 Implantable cardioverter-defibrillators (ICDs) terminate VT episodes, reducing the risk of sudden death. Recurrent VT develops in 40% to 60% of patients who receive an ICD after an episode of spontaneous sustained VT. A first episode of VT occurs in 20% of patients within ...
متن کاملCatheter ablation of ventricular tachycardia.
Ventricular tachycardia (VT) most commonly develops in patients with structural heart disease. Myocardial infarction results in collagen replacement interspersed with surviving myocardium, which alters impulse propagation, facilitating re-entry.1 Aside from the postinfarction substrate, scar-mediated VT occurs in patients with nonischemic cardiomyopathy, Chagas disease, sarcoidosis, arrhythmoge...
متن کاملA Novel Means of Cardiac Catheter Guidance for Ablation Therapy of Ventricular Tachycardia
LIBRARIES The author hereby grants to MIT permission to reproduce and to distribute publicly paper and electronic copies of this thesis document in whole or in part in any medium now known or hereafter created. Abstract This work presents a system for identifying the site of origin of ventricular tachycardia (VT) and guiding a catheter to that site in order to deliver radio-frequency (RF) ablat...
