Radiofrequency 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 کاملClinical and electrophysiological spectrum of idiopathic ventricular outflow tract arrhythmias.
OBJECTIVES This study sought to compare and contrast the clinical and electrophysiological characteristics of outflow tract arrhythmias. BACKGROUND Idiopathic ventricular outflow tract arrhythmias manifest clinically in 3 forms: 1) paroxysmal sustained monomorphic ventricular tachycardia (SMVT), 2) repetitive nonsustained ventricular tachycardia (NSVT), or 3) premature ventricular contraction...
متن کاملIdiopathic ventricular outflow tract tachycardia.
Although the pathogenesis of ventricular outflow tract tachycardia has not been fully elucidated, recent findings suggest that defects in cAMP signalling may be involved.
متن کامل10-year follow-up after radiofrequency ablation of idiopathic ventricular arrhythmias from right ventricular outflow tract
BACKGROUND The aim of this study was to examine the effect of radiofrequency ablation (RFA) of ventricular arrhythmias from right ventricular outflow tract (RVOT) during long-term follow-up. METHODS A follow-up analysis was conducted using an in-house questionnaire, as well as a qualitative assessment of the patients' medical records. The study population of 34 patients had a previous diagnos...
متن کاملGender Difference in Idiopathic Right Ventricular Outflow Tract-Ventricular Tachycardia.
BACKGROUND Few studies have discussed gender differences in idiopathic right ventricular outflow tract-ventricular tachycardia (RVOT-VT). This study explored possible gender differences in electrophysiological characteristics and catheter ablation for idiopathic RVOT-VT in Taiwan. METHODS Ninety-three patients (mean age 38.7 ± 15.5years, 30 males) were diagnosed as having idiopathic RVOT-VT b...
