Unusual site of origin of a non-automatic focal right ventricular tachycardia.
نویسندگان
چکیده
Focal right ventricular tachycardia is relatively uncommon. It usually arises from specific anatomic locations. A 59-year-old woman with a structurally normal heart and an automatic cardioverter-defibrillator implanted beforehand presented with drug-resistant incessant ventricular tachycardia for which 1786 anti-tachycardia pacing therapies and 119 shocks had been delivered. Electroanatomical mapping showed focal tachycardia originating from the acute margin of the right ventricle. Irrigated catheter ablation was performed successfully.

BACKGROUND The aim of this study was to investigate the different substrate characteristics of repetitive premature ventricular complexed (PVC) trigger sites by the non-contact mapping (NCM). METHODS Thirty-five consecutive patients, including 14 with arrhythmogenic right ventricular cardiomyopathy/dysplasia (ARVC) and 21 with idiopathic right ventricular outflow tract tachycardia (RVOT VT), ...
متن کاملArrhythmogenic Right Ventricle in Left Ventricular Non-compaction - In response to "Right Ventricular Ablation as a Therapeutic Option for Left Ventricular Hypertrabeculation / noncompaction"
We welcome Dr Finsterer's and Dr Stollberger's interest in our manuscript and their insightful observations. We have recently reported [1] a case of successful mapping and ablation of ventricular tachyarrhythmia in a patient with left ventricular non-compaction (LVNC). The arrhythmia proved to have a rather unusual and unexpected origin, located within a structurally normal right ventricle (RV)...
متن کاملAccuracy of the unipolar electrogram for identification of the site of origin of ventricular activation.
INTRODUCTION The purpose of this study was to determine the accuracy of the unipolar electrogram for identifying the earliest site of ventricular activation. The earliest site of ventricular activation may be identified with the unipolar electrogram by the absence of an R wave. However, the accuracy of this technique is unknown. METHODS AND RESULTS A single ventricular premature complex was i...
متن کاملRadiofrequency catheter ablation for idiopathic right ventricular tachycardia with special reference to morphological variation and long-term outcome.
OBJECTIVE To assess the long term outcome of radiofrequency (RF) catheter ablation for idiopathic ventricular tachycardia (VT) originating from the outflow tract of the right ventricle, with special reference to the morphological variation in the VT-QRS complexes. PATIENTS 13 patients whose ventricular tachycardia was treated with RF ablation were followed up more than 18 months after RF abla...
متن کاملMapping and Surgical Ablation of Focal Epicardial Left Ventricular Tachycardia
We describe a technical challenge in a 17-year-old patient with incessant epicardial focal ventricular arrhythmia and diminished LV function. Failure of ablation at the earliest activated endocardial site during ectopy suggested an epicardial origin, which was supported by specific electrocardiographic criteria. Epicardial ablation was not possible due to the localization of the origin of the v...
