Implantable Cardioverter-Defibrillator Leads

Implantable cardioverter-defibrillator in a patient with dextrocardia situs inversus

Background: Dextrocardia is a congenital anomaly, which may have coexistent coronary artery disease (CAD), arrhythmias and conventional indications for device therapy. However, the implantation of transvenous leads can be technically challenging and the approach needs to be tailored to the patient's individual anatomy. Case presentation: A 54-year-old male with dextrocardia situs inversus and i...

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...

Learning from implantable cardioverter-defibrillator leads in children.

I f you want something broken, give it to your kid. That truism applies to many items, from toys to technology. The article describing the results of the Pediatric Lead Extractability and Survival Evaluation (PLEASE) study by Atallah et al 1 in this issue of Circulation provides sobering but important evidence that this also applies to implantable cardioverter-defibrillator (ICD) leads. Most IC...

Risk of failure of transvenous implantable cardioverter-defibrillator leads.

BACKGROUND Despite the positive effect on mortality in selected patients, implantable cardioverter-defibrillator therapy is also associated with potential malfunction of the implanted system. The present study provides the long-term lead failure rate in a large single-center cohort. METHODS AND RESULTS Since 1992, a total of 2068 implantable cardioverter-defibrillator patients with 2161 defib...
