Malignant entity of idiopathic ventricular fibrillation and polymorphic ventricular tachycardia initiated by premature extrasystoles originating from the right ventricular outflow tract.
OBJECTIVES The aim of this study was to assess the clinical characteristics and the efficacy of radiofrequency catheter ablation (RFCA) for idiopathic ventricular fibrillation (VF) and/or polymorphic ventricular tachycardia initiated by ventricular extrasystoles originating from the right ventricular outflow tract (RVOT). BACKGROUND Ventricular fibrillation and/or polymorphic ventricular tach...
متن کاملGender differences in electrophysiological characteristics of idiopathic ventricular tachycardia originating from right ventricular outflow tract.
It has become increasingly apparent in recent years that there are important differences of many cardiovascular disorders including ventricular tachycardias in men and women. Nevertheless, so far just few studies have addressed possible gender differences in electrophysiological characteristics of idiopathic ventricular tachycardia from right ventricular outflow tract (RVOT-VT), other than epid...
متن کاملRadiofrequency catheter ablation of premature ventricular contractions originating in the right ventricular outflow tract.
OBJECTIVES To evaluate if radiofrequency catheter ablation is an effective procedure for the treatment of right ventricular outflow tract premature ventricular contractions (RVOT-PVC) and ascertain if it results in an improvement of symptoms. METHODS A prospective study with 30 consecutive patients (mean age 40 +/- 13 years, 25 females), with no apparent structural cardiopathy, with very freq...
متن کامل[Ablation of premature ventricular contractions originating in the right ventricular outflow tract using non-contact mapping].
Premature ventricular contractions originating in the right ventricular outflow tract may respond poorly to pharmacological treatment, and ablation using conventional fluoroscopically-guided systems may be complicated by the difficulty in inducing arrhythmias. We describe the use of a non-contact mapping system to ablate difficult-to-induce premature ventricular contractions originating in the ...
متن کاملCatheter Ablation of Idiopathic Premature Ventricular Contractions and Ventricular Tachycardias Originating from Right Ventricular Septum
BACKGROUND Idiopathic premature ventricular contractions (PVCs) and ventricular tachycardias (IVTs) originating from the subtricuspid septum and near the His bundle have been reported. However, little is known about the prevalence, distribution, electrocardiographic characteristics and the efficacy of radiofrequency catheter ablation (RFCA) for the ventricular arrhythmias arising from the right...
