BACKGROUND The subcutaneous implantable cardioverter-defibrillator (S-ICD) is recognized as a viable alternative to the transvenous ICD. The safety and efficacy of this device has been demonstrated in Western countries, but studies with S-ICD implantation in Japanese patients have not been reported. METHODS AND RESULTS Twelve patients received an S-ICD implant in our institute between Februar...

Introduction Although transvenous pacemakers and implantable cardioverter-defibrillators (ICD) have long been the standard of care, they are not without significant drawbacks. In recent years, major advances have been achieved in leadless pacemaker technology and entirely subcutaneous ICD (S-ICD) systems that obviate intracardiac leads and hence carry the potential to reduce associated complica...

The shift from version 9 to version 10 of the ICD-code (“International Statistical Classification of Diseases and Related Health Problems”) causes enormous problems for the exploitation of medical data warehouses, since conventional data warehouses do not support the change of the structure of dimensions, i.e. the content and relationships of master data like the diagnostic codes, or other key ...

BACKGROUND Cardiac-resynchronization therapy (CRT) benefits patients with left ventricular systolic dysfunction and a wide QRS complex. Most of these patients are candidates for an implantable cardioverter-defibrillator (ICD). We evaluated whether adding CRT to an ICD and optimal medical therapy might reduce mortality and morbidity among such patients. METHODS We randomly assigned patients wi...

BACKGROUND Despite the survival benefit of implantable-cardioverter-defibrillators (ICDs), the vast majority of patients receiving an ICD for primary prevention do not receive ICD therapy. We sought to assess the role of heterogeneous scar area (HSA) identified by late gadolinium enhancement cardiovascular magnetic resonance (LGE-CMR) in predicting appropriate ICD therapy for primary prevention...

This research study examined the usefulness of the ICD-10-CM system in capturing public health diseases (reportable diseases or the nationally notifiable infectious diseases, leading causes of death, and morbidity/mortality related to terrorism), when compared to ICD-9-CM.1-3 It also examined agreement levels of coders when coding public health diseases in both ICD-10-CM and ICD-9-CM. Overall r...

AIMS There are limited data regarding the effect of diabetes mellitus (DM) on the risks of both appropriate and inappropriate implantable cardioverter defibrillator (ICD) therapy. The present study was designed to compare the outcome of appropriate and inappropriate ICD therapy in patients with or without DM. METHODS AND RESULTS The risk of a first appropriate ICD therapy for ventricular tach...

This paper outlines the approach that the WHO's Family of International Classifications (WHO-FIC) network is undertaking to create ICD-11. We also outline the more focused work of the Quality and Safety Topic Advisory Group, whose activities include the following: (i) cataloguing existing ICD-9 and ICD-10 quality and safety indicators; (ii) reviewing ICD morbidity coding rules for main conditio...

BACKGROUND Multiple clinical trials have shown that a properly functioning implantable cardioverter-defibrillator (ICD) is capable of interrupting sudden death caused by ventricular tachyarrhythmias. However, ICDs are complex medical devices, and they do not always perform as expected or they may fail completely. Exposure of ICD recipients to professional or media reports that their specific de...

BACKGROUND The aim of this study was to evaluate the overall use of implantable cardioverter defibrillators (ICD) for primary prevention of sudden cardiac arrest (SCA), among eligible patients from an outpatient cardiology clinic and to determine what factors might contribute to underutilization of ICDs. METHODS This report was a retrospective chart review of patients with ischemic or non-isc...
