BACKGROUND The Multicenter Automatic Defibrillator Implantation Trial-Reduce Inappropriate therapy (MADIT-RIT) trial showed a significant reduction in inappropriate implantable cardioverter defibrillator (ICD) therapy in patients programmed to high-rate cut-off (Arm B) or delayed ventricular tachycardia therapy (Arm C), compared with conventional programming (Arm A). There is limited data on th...

Introduction In cases of patients who have contraindications to transvenous pacing leads but still require pacing, surgically placed epicardial pacing leads are often used. If such a patient warranted implantable cardioverter-defibrillator (ICD), a subcutaneous ICD (S-ICD) system would be ideal from the standpoint of avoidance of transvenous leads, but devicedevice interaction with the epicardi...

Fro of D Re Hu an Me rec Me rel Ma OBJECTIVES This study aims to conduct a meta-analysis comparing efficacy and safety outcomes between subcutaneous implantable cardioverter-defibrillator (S-ICD) and transvenous implantable cardioverter-defibrillator

The implantable cardioverter-defibrillator (ICD) is effective to prevent sudden cardiac death (SCD) in selected patients with heart disease known to be at high risk for ventricular arrhythmia. Nevertheless, this invasive and definitive therapy is not indicated in patients with potentially transient or reversible causes of sudden death, or in patients with temporary contra-indication for ICD pla...

Current guidelines for implantable cardioverter-defibrillator (ICD) therapy in heart failure patients were established by multiple device trials; however, very few geriatric patients (patients ≥ 65 years old) were included in these studies. This article explores the controversies of ICD implantation in the geriatric population, management of delivered ICD therapy in this age group, and the end ...

Ever since its development by Dr. Michel Mirowski in the 1970s and its use in clinical practice in 1980, the implantable cardioverter-defibrillator (ICD) has improved survival in patients presenting with sustained ventricular tachycardia and ventricular fibrillation. Three recent randomized studies—Antiarrhythmic Drugs versus Implantable Defibrillator (AVID) (1), Canadian Implantable Defibrilla...

The implantable cardioverter-defibrillator (ICD) has been shown to improve survival in patients at high risk for sudden cardiac arrest (SCA). However, there remain situations in which an ICD may be inappropriate: the high risk for SCA is temporary, there is need for interruption of implanted ICD therapy (e.g. for infection), there is temporary inability to implant an ICD, there is bridge period...

UNLABELLED Catecholaminergic polymorphic ventricular tachycardia (CPVT) is an electrophysiological disorder of a physically normal heart that occurs in children when the body is subjected to intense emotional or physical stress that causes adrenergic discharge. This troubling disease can be sporadic (spontaneous) or familial (genetic/inherited). Unfortunately, its associated ventricular tachyca...
