Contrast-enhanced CMR imaging of ventricular tachycardia isthmus sites to guide ablation: an approach in evolution.
SEE PAGE 774 T he mechanism of ventricular tachycardia (VT) in patients with structural heart disease is primarily scar-related reentry (1). Although any disease process that results in the formation of myocardial scar can predispose to reentrant VT, the best characterized substrate is post-myocardial infarction VT. After myocardial infarction, ventricular tissue can be classified into 3 types:...
متن کاملA 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 کاملThree-dimensional 123I-meta-iodobenzylguanidine cardiac innervation maps to assess substrate and successful ablation sites for ventricular tachycardia: feasibility study for a novel paradigm of innervation imaging.
BACKGROUND Innervation is a critical component of arrhythmogenesis and may present an important trigger/substrate modifier not used in current ventricular tachycardia (VT) ablation strategies. METHODS AND RESULTS Fifteen patients referred for ischemic VT ablation underwent preprocedural cardiac (123)I- meta-iodobenzylguanidine ((123)I-mIBG) imaging, which was used to create 3-dimensional (3D)...
متن کاملEpicardial unipolar radiofrequency ablation for left ventricular aneurysm related ventricular arrhythmia
We report a case of a 62-year-old Chinese man with typical triple-vessel lesions and apical left ventricular aneurysm accompanied with ventricular tachycardia. Off-pump coronary artery bypass (OPCAB) grafting was performed in combination with epicardial unipolar radiofrequency ablation and linear closure of left ventricular aneurysm. The patient recovered well without postoperative complication...
متن کاملEffects of local cardiac denervation on cardiac innervation and ventricular arrhythmia after chronic myocardial infarction
BACKGROUND Modulation of the autonomic nervous system (ANS) has already been demonstrated to display antiarrhythmic effects in patients and animals with MI. In this study, we investigated whether local cardiac denervation has any beneficial effects on ventricular electrical stability and cardiac function in the chronic phase of MI. METHODS Twenty-one anesthetized dogs were randomly assigned i...
