Response by Friedman and Al-Khatib to Letter Regarding Article, “Ventricular Fibrillation Conversion Testing After Implantation of a Subcutaneous Implantable Cardioverter Defibrillator: Report From the National Cardiovascular Data Registry”

Implantation of the Subcutaneous Implantable Cardioverter-Defibrillator

The subcutaneous implantable cardioverter-defibrillator (S-ICD) was introduced to reduce acute transvenous leadrelated complications, such as pneumothorax, endocarditis, cardiac perforation, and lead dislodgements, as well as the complications related to chronic indwelling leads, such as lead failure, venous obstruction, and bacteremia. The standard implantation technique of the S-ICD involves ...

Cardiac perforation from implantable cardioverter-defibrillator lead placement: insights from the national cardiovascular data registry.

BACKGROUND Cardiac perforation is a feared complication of implantable cardioverter-defibrillator (ICD) lead implantation because of the potential for significant morbidity and mortality. Predictors of perforation and the severity of associated adverse events have not been well studied. We sought to identify predictors of cardiac perforation from ICD lead implantation and subsequent outcomes. ...

Development of ventricular fibrillation after implantation of a biventricular implantable cardioverter defibrillator: what is the mechanism?

Syncopal spells in heart failure patient with cardiovascular implantable electronic devices (CIED) require multiple assessments. T-wave oversensing is a well-described phenomenon that remains significant in modern implantable cardioverter defibrillators (ICD) systems. It can lead to inappropriate therapies and loss of biventricular pacing in those with cardiac resynchronization devices. Strateg...

Subcutaneous implantable cardioverter-defibrillator.

or nearly 3 decades, the implantable cardioverter-defibrillator (ICD) has been available to patients who survived life-threatening rapid heart rhythms or are at risk of experiencing them. The ICD comprises a device generator coupled with a defibrillation lead. Traditional ICDs are implanted under the skin with the generator positioned beneath the collar bone. The defibrilla-tion lead is inserte...
