Radiofrequency catheter ablation for ventricular tachycardia.
Radiofrequency energy was used for the ablation of chronic recurrent ventricular tachycardia (VT) in 58 patients who were divided into two groups: 44 cases with structural myocardial disease (36 men and 8 women: mean age 55 years; range: 14 to 85 years) with an average left ventricular ejection fraction of 38% (range: 15 to 80%): these patients had myocardial infarction (28 cases), arrhythmogen...
متن کاملRadiofrequency catheter ablation of ventricular tachycardia guided by intracardiac echocardiography.
AIMS Ventricular tachycardia (VT) frequently has an anatomical substrate. Identification of areas prone to arrhythmogenicity facilitates radiofrequency catheter ablation (RFCA). Furthermore, direct monitoring of complications potentially increases safety of RFCA. The aim of this study was to evaluate the feasibility of guiding RFCA of VT with intracardiac echocardiography (ICE), in order to imp...
متن کاملCatheter ablation for ventricular tachycardia.
Sustained ventricular tachycardia (VT) is an important cause of morbidity and sudden death in patients with heart disease.1 Implantable cardioverter-defibrillators (ICDs) terminate VT episodes, reducing the risk of sudden death. Recurrent VT develops in 40% to 60% of patients who receive an ICD after an episode of spontaneous sustained VT. A first episode of VT occurs in 20% of patients within ...
متن کاملRadiofrequency catheter ablation of ventricular tachycardia after myocardial infarction.
BACKGROUND Patients with ventricular tachycardia (VT) after myocardial infarction often have multiple morphologies of inducible VT, which complicates mapping and is viewed by some as a relative contraindication to ablation. Attempting to identify and target a single "clinical" VT is often limited by inability to obtain 12-lead ECGs of VTs that are terminated emergently or by defibrillators. Thi...
متن کاملRadiofrequency Catheter Ablation for Supraventricular Tachycardia
C atheter ablation for nonpharmacological management of pediatric patients with tachyarrhythmias has evolved during the past approximately 10 years. Direct-current energy ablation was initially used in some patients with drug-refractory, life-threatening tachyarrhythmias such as junctional ectopic-focus tachycardia and also for some children with left ventricular dysfunction due to incessant ta...
