Ablation of idiopathic ventricular arrhythmias
Idiopathic ventricular arrhythmias (IVA) is a term commonly used to describe premature ventricular complexes (PVCs) or ventricular tachycardias (VT) in the absence of structural heart disease. Most IVA (approximately 70%) arise from the right ventricular outflow tract (RVOT) and can be recognised on the ECG by a left bundle branch morphology of the QRS complex, an inferior axis, and an R/S tran...
متن کاملCatheter Ablation of Ventricular Arrhythmias: Clinical Vignettes
Ventricular arrhythmias (VA) can develop in patients with structural heart disease (SHD) including prior myocardial infarction and nonischemic cardiomyopathy. When VAs manifest in structurally normal hearts, they are usually a result of intra-cellular calcium overload (triggered activity) or an abnormal response to adrenergic stimulation (automaticity).1 Reentry within the Purkinje fibers and s...
متن کاملCatheter ablation of symptomatic idiopathic ventricular arrhythmias
Aims This study was designed to gain insight into the patient characteristics, results and possible complications of ablation procedures for symptomatic idiopathic premature ventricular complexes (PVC) and idiopathic ventricular tachycardia (VT). Methods Data were collected from all patients who underwent radiofrequency catheter ablation for symptomatic PVCs and idiopathic VT in the Catharina H...
متن کاملAblation of ventricular arrhythmias in arrhythmogenic right ventricular dysplasia.
Arrhythmogenic right ventricular dysplasia (ARVD) is a genetically determined myocardial disease characterized by fibrofatty replacement of the right ventricular wall. Ventricular tachyarrhythmias can be seen in the early stages of the disease, which is one of the most important causes of sudden death in young healthy individuals. Radiofrequency (RF) catheter ablation is an option for the treat...
متن کاملPercutaneous epicardial ablation in ventricular arrhythmias.
INTRODUCTION Reentrant circuits of ventricular tachycardia may involve not only the endocardium but also the epicardium. Epicardial ablation can be useful in these situations. OBJECTIVE The aim of this study was to assess efficacy, safety and complications in a series of consecutive patients who underwent ablation of ventricular tachycardia with epicardial mapping. METHODS The study include...
