Antiarrhythmic Drug Therapy to Avoid ICD Shocks
Author(s): Jaber Abboud , Joachim R Ehrlich Added: 3 years ago
Implantable cardioverter defibrillators (ICDs) have been used for over 30 years to prevent sudden cardiac death (SCD). The first indications for ICD placement were secondary prevention; later trials demonstrated a primary prevention benefit of ICD therapy in patients at risk of SCD. ICD therapy prolongs life in both patient populations.1 However, the efficacy of an ICD depends on its ability to… View more

Significance of Shocks in Implantable Cardioverter Defibrillator Recipients
Author(s): Anthony C Li , Amit Kaura , Nicholas Sunderland , et al Added: 3 years ago
Since the 1990s, the publication of several large randomised controlled trials (RCTs) have established the efficacy of implantable cardioverter defibrillator (ICD) therapy in reducing the risk of sudden cardiac death (SCD) in high-risk patients. Collectively these trials have demonstrated a significant all-cause mortality reduction compared with medical therapy alone, for both the primary and… View more

EHRA 2019: Internal vs. External Electrical Cardioversion of Atrail Arrhythmias in Patients With an Implantable Cardioverter-Defibrillator (ICD)
Author(s): Jakob Luker Added: 5 years ago
Dr Jakob Lüker (University Hospital Cologne, DE) discusses internal vs. external electrical cardioversion of atrail arrhythmias in patients with an implantable cardioverter-defibrillator (ICD). Filmed on site by Radcliffe Cardiology. Questions: 1. What is the concern with atrial conversions in patients with AICDs (automated implantable cardioverter defibrillator)? (00:10) 2. How does… View more

Electrophysiology & Arrhythmia
Author(s): Angelo Auricchio Added: 3 years ago
Despite the fact that more than 20 years have passed since the clinical introduction of cardiac resynchronisation therapy (CRT), one of the key questions – do we need an ICD for primary prevention of sudden cardiac death (SCD) in CRT patients? – is still unanswered. Prospective Randomised Controlled Trials Multiple prospective randomised controlled trials have been conducted to establish the… View more

Numerous large clinical trials have demonstrated the benefit of implantable cardioverter-defibrillators (ICDs) to prevent sudden cardiac death (SCD) in selected populations.1,2 These results and advances in defibrillation therapies have led to an impressive expansion of ICD implants and indications in recent decades. Although initially focusing on secondary prevention, current ICD indications… View more

Defibrillation Threshold Testing: Current Status
Author(s): Justin Hayase , Duc H Do , Noel G Boyle Added: 3 years ago
The ICD is an important therapy for both primary and secondary prevention of sudden cardiac death in selected patients. The role for defibrillation threshold (DFT) testing either intraoperatively or postoperatively has changed significantly over the past few decades, and it is no longer routinely recommended in patients undergoing left-sided transvenous ICD implantation.1–7 The definition of the… View more

Author(s): Dietmar Bänsch Added: 3 years ago
For more than three decades, the implantable cardioverter defibrillator (ICD) has proven to be a well-established, main therapeutic tool for the primary and secondary prevention of sudden cardiac death due to malignant ventricular arrhythmias.1 One of the standard practice concepts is defibrillation (DF) testing. Defibrillation testing has been considered a mandatory part at the time of… View more

Contemporary ICDs: What Does the Latest Data Say?
Author(s): Angelo Auricchio , Anne B Curtis Added: 4 months ago
Prof Anne Curtis (University of Buffalo, US) and Prof Angelo Auricchio (Fondazione Cardiocentro Ticino, CH) discuss contemporary clinical data of Implantable Cardioverter Defibrillators (ICDs) from real world populations. The discussion is focused on the importance and impact of ICD therapy on prevention of sudden cardiac death by analysing the latest presented data.In context, the data analysed… View more
