The Antiarrhythmics Versus Implantable Cardioverter-Defibrillator (AVID), Cardiac Arrest Study Hamburg (CASH) and the Canadian Implantable Defibrillator Study (CIDS) trials demonstrated that the implantable cardioverter-defibrillator (ICD) was superior to best drug therapy for prolonging survival inpatients with sustained ventricular tachycardia/fibrillation (VT/VF). Substudies of AVID demonstr...
We describe the successful implantation of a cardioverter-defibrillator (ICD) in two pregnant women with hypertrophic cardiomyopathy at high risk. The indication of ICD and the necessary care for ICD implantation during pregnancy are discussed and were the main objectives of this case report.
Objectives: To assess the incidence and electrophysiological characteristics of spontaneous ventricular tachyarrhythmias after implantable cardioverter-defibrillator (ICD) implantation for primary prevention. Design: Prospective observational study. Patients: 41 consecutive patients, who fulfilled MADIT (multicenter automatic defibrillator implantation trial) I criteria, except for suppressibil...
OBJECTIVES To assess the incidence and electrophysiological characteristics of spontaneous ventricular tachyarrhythmias after implantable cardioverter-defibrillator (ICD) implantation for primary prevention. DESIGN Prospective observational study. PATIENTS 41 consecutive patients, who fulfilled MADIT (multicenter automatic defibrillator implantation trial) I criteria, except for suppressibi...
A 50-year-old man, who underwent a procedure for an implantable cardioverter defibrillator (ICD), visited the outpatient department of our clinic after suffering multiple ICD shocks. The ICD interrogation revealed recurrent shock due to a high frequency of noise that is sensed by the device as ventricular fibrillation. Chest radiography revealed a significant split in the insulation of the lead...
The benefit of implantable cardioverter-defibrillator (ICD) therapy depends upon appropriate evaluation of a persisting risk of sudden death and estimation of the patient's overall survival. Assessment of a stable and unchangeable arrhythmogenic substrate is often difficult. Structural abnormality and ventricular dysfunction, the two major risk parameters, may recover, and heart failure symptom...
Primary prophylaxis of sudden cardiac death by implantable cardioverter-defibrillator (ICD) treatment will greatly increase ICD implant numbers. This will have major cost and infrastructure consequences. Those studies that have demonstrated the clinical need have been industry driven. Whether their conclusions should now expand ICD indications is debated, but it would be perverse to suggest tha...
BACKGROUND The impact of patient age on the risks of death or rehospitalization after primary prevention implantable cardioverter-defibrillator (ICD) placement is uncertain. METHODS AND RESULTS Data from 5 major ICD trials were merged: the Multicenter Automatic Defibrillator Implantation Trial I (MADIT-I), the Multicenter UnSustained Tachycardia Trial (MUSTT), the Multicenter Automatic Defibr...
BACKGROUND The benefit of novel implantable cardioverter defibrillator (ICD) programming in reducing inappropriate ICD therapy and mortality was demonstrated in Multicenter Automatic Defibrillator Implantation Trial-Reduce Inappropriate Therapy (MADIT-RIT). However, the cause of mortality reduction remains incompletely evaluated. We aimed to identify factors associated with mortality, with focu...
OBJECTIVES We aimed to evaluate the relationship between echocardiographic response to cardiac resynchronization therapy (CRT) and the risk of subsequent ventricular tachyarrhythmias (VTAs). BACKGROUND Current data regarding the effect of CRT on the risk of VTA are limited and conflicting. METHODS The risk of a first appropriate implantable cardioverter-defibrillator (ICD) therapy for VTA (...
