the usage of implantable cardiac defibrillator (icd) since 1980s is becoming more popular these days. the rate of both, endocarditis and constrictive pericarditis are low but it still needs attention. we are reporting a rare case of icd endocarditis as a result of toe infection in a diabetic patient. this was followed by infectious pericarditis after device removal by open heart surgery and the...

Several technologies developed for the Transit Navigation System were later transferred to implantable medical devices. These devices include pacemakers, the Automatic Cardiac Implantable Defibrillator, and the Programmable Implantable Medication System for the treatment of diabetes. All of these applications employ Transit-derived telemetry and command systems for programming and data retrieva...

Among 58 consecutive patients who underwent electrophysiologic testing for risk assessment and who subsequently received a third-generation implantable cardioverter-defibrillator, 39 had ventricular tachycardia induced in the baseline state and 19 had ventricular tachycardia induced only after administration of intravenous procainamide, increasing the yield of electrophysiologic risk assessment...

Sarcoidosis is a granulomatous disease of unknown pathogenesis that can affect virtually any organ system. Cardiac involvement results in significant morbidity and mortality, with some studies reporting that cardiac involvement accounts for up to 25% of all deaths from sarcoidosis in the United States and more than half of all deaths in Japan. Many deaths seem to be arrhythmic in nature and are...

BACKGROUND A conceptualized model may be useful for understanding risk stratification of primary prevention implantable cardioverter defibrillators considering the competing risks of appropriate implantable cardioverter defibrillator shock versus mortality. METHODS AND RESULTS In a prospective, multicenter, population-based cohort with left ventricular ejection fraction ≤35% referred for prim...

BACKGROUND A negative electrophysiology study (EPS) may delineate a subgroup of patients with severely impaired left ventricular ejection fraction (LVEF) whose care can be safely managed long-term without an implantable cardioverter-defibrillator. METHODS AND RESULTS Consecutive patients treated with primary percutaneous coronary intervention for ST-segment-elevation myocardial infarction und...

Long QT syndrome (LQTS) can present with syncope and seizure-like activity in the setting of torsades de pointes (TdP) with hemodynamic instability. Electrolyte abnormalities and medications can predispose to TdP in the setting of latent LQTS. An implantable cardioverter defibrillator (ICD) is needed if patients with TdP continue to be symptomatic despite medical treatment. We report a case of ...

Sudden cardiac death (SCD) is the most important cause of death in the industrialised world. Treatment with antiarrhythmic drugs (AAD), however, proved disappointing in preventing SCD. From drugs with electrophysiological properties, only treatment with beta-blockers has been shown to improve clinical outcome. This lack of efficiency of AADs heralded a new era of secondary and primary preventio...
