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...

Since implantable cardioverter-defibrillators (ICDs) were first introduced, defibrillator threshold (DFT) testing was considered an integral part of the implant procedure. Perform‐ ing DFT testing verifies the ability of the ICD in detecting and aborting the lethal arrhythmia it was designed to treat. The process has evolved with the development of the ICD’s and the expanding indications for th...

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...

An 81-year-old man was referred with an infected cardiac resynchronization therapy defibrillator (CRT-D) system. His initial dualchamber implantable cardioverter-defibrillator (ICD) had been implanted 8 years earlier and upgraded to a CRT-D system 2 years before referral. Epicardial atrial and left ventricular (LV) leads were subsequently added after the endocardial LV lead lost capture. The en...

This report described an 81-year-old woman with severe symptomatic heart failure, reduced ejection fraction, mitral regurgitation, and an electrocardiographic QRS width of 118 ms who had ventricular dyssynchrony identified by echocardiographic tissue synchronization imaging. Because of her severe heart failure symptoms on maximal medical therapy, referral to implant a defibrillator, and mechani...

The implantable cardioverter defibrillator (ICD) has significantly improved survival in patients with an increased risk of sudden cardiac death (SCD). The wearable cardioverter defibrillator (WCD) is an alternative to the ICD in patients with a transient ICD indication or those in whom an ICD temporarily cannot be implanted. We describe here the technical details of the WCD and report three pat...

A persistent left superior vena cava (PLSVC) was present in a 74 year-old man with dilated cardiomyopathy undergoing implantation of a cardiac resynchronization therapy device with defibrillator (CRT-D). A dual-coil active-fixation defibrillator lead was positioned in the right ventricular apex, followed by a SonR active fixation lead in the right atrial free wall. The coronary sinus lead was a...

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 The factors that determine the risk for sudden death or implantable cardioverter defibrillator therapy in patients receiving cardiac resynchronization therapy (CRT) therapies are largely unknown. METHODS AND RESULTS We hypothesized that clinical measures of heart failure severity and the presence of comorbid conditions would predict the risk of malignant arrhythmias in the 1520 pat...

Introduction The subcutaneous implantable cardioverter-defibrillator (S-ICD) is a safe and effective treatment for prevention of sudden cardiac death. It is typically not used in patients who require additional therapies conferred by transvenous implantable cardioverter-defibrillator (TV-ICD) systems, such as bradycardia pacing or antitachycardia pacing (ATP) for ventricular tachycardia (VT). D...
