Given the unique interventional emphasis in our specialty, Teaching Rounds in Cardiac Electrophysiology has frequently centered on the pearls and pitfalls associated with electrogram analysis and complications of lead implant extraction or ablation and in mapping complex arrhythmia circuits. In this issue of Circulation: Arrhythmia and Electrophysiology, Fabrizio et al, in a refreshing departur...

Sudden cardiac death (SCD) from arrest is a major international public health problem accounting for an estimated 15%-20% of all deaths. Implantable cardioverter defibrillators (ICD) have been demonstrated to improve survival in high-risk populations. While 500,000 patients experience SCD annually, there are only 75,000 ICDs implanted annually suggesting significant treatment gap. To determine ...

As one of the most common neurological disabilities in young adults, Multiple sclerosis (MS) has characteristics of inflammation, demyelination, neuro-axonal damage, and progressive prolonged disability. The disease is clinically divided into three general categories according to response to treatment: Relapsing-Remitting MS (RRMS), Primary Progressive MS (PPMS) and Secondary Progressive MS (SP...

Auckland City Hospital provides electrophysiology (EP) procedures for people residing in the Northern Region and is a national service paediatric congenital cardiac patients. Electrophysiology are primarily therapeutic typically undertaken with view to ablation. When ablation not delivered, these considered diagnostic. This retrospective study was explore clinical characteristics outcomes of pa...

OBJECTIVES The purpose of this study was to evaluate a new technique for sterilizing nonlumen electrophysiology catheters that uses hydrogen peroxide gas plasma. BACKGROUND The reuse of electrophysiology catheters may potentially result in a significant cost savings. While ethylene oxide sterilization appears to be safe and effective from a clinical standpoint, toxic ethylene oxide residuals,...
