Catheter 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 کاملOutcomes of cardiac perforation complicating catheter ablation of ventricular arrhythmias.
BACKGROUND Cardiac perforation is a recognized complication of catheter ablation procedures, most commonly encountered during ablation of atrial fibrillation. The study aims to investigate the incidence, management, and hospital outcomes of cardiac perforation complicating catheter ablation for ventricular arrhythmias. METHODS AND RESULTS Consecutive patients undergoing catheter ablation for ...
متن کاملRadiofrequency Catheter Ablation of Idiopathic Right Ventricular Outflow Tract Arrhythmias
Idiopathic ventricular arrhythmias (VA) consist of various subtypes of VA that occur in the absence of clinically apparent structural heart disease. Affected patients account for approximately 10% of all patients referred for evaluation of ventricular tachycardia (VT). Arrhythmias arising from the outflow tract (OT) are the most common subtype of idiopathic VA and more than 70-80% of idiopathic...
متن کامل[Left ventricular dysfunction induced by monomorphic ventricular arrhythmias: large improvement in ventricular function after radiofrequency ablation of the arrhythmic source].
Left ventricular systolic dysfunction related to ventricular arrhythmias is a relatively poorly understood entity. To increase our knowledge base, we describe 5 patients in whom the link between ventricular dysfunction and ventricular arrhythmia was unequivocally established. All patients had repetitive monomorphic ventricular arrhythmias and left ventricular systolic dysfunction (ejection frac...
