BACKGROUND Due to an aging population the incidence of both cardiac and tumor-related illnesses is increasing. A problem may arise if radiotherapy is necessary in close anatomic proximity to an implantable cardioverter-defibrillator (ICD). These highly precise devices may respond to ionizing radiation with a loss of function or uncontrolled stimulation, with both effects being potentially life ...

Introduction Catheter ablation is used to control ventricular arrhythmias (VT/VF) in a multitude of substrates. MR can delineate regions of scar and may guide ablation procedures, however the presence of an ICD has been an issue both for safety and MR image quality. Recent studies have demonstrated acceptable safety for scanning of device patients in certain circumstances, but efficacy has not ...

A 75 year-old man with a Biotronik Lumax VR-T540 uncommitted implantable cardioverter-defibrillator (ICD) received a shock during general anesthesia for the resection of a basal cell carcinoma on the nose. The surgeon who was unaware of the ICD, used unipolar electrocautery during the procedure. No ICD parameters were reprogrammed preoperatively and the device remained programmed as follows: Lo...

AIMS With improved survival of patients with congenital and inherited heart disease, there is now a younger cohort of patients with an implantable cardioverter defibrillator (ICD) for the prevention and treatment of ventricular dysrrhythmias. Young women with such disorders often wish to embark on pregnancy, but pregnancy outcome data for this group is sparse. We therefore evaluated pregnancy o...

A 39-year-old Caucasian female with hypertrophic obstructive cardiomyopathy and with history of syncope and other high-risk features for sudden cardiac death underwent implantation of St Jude Photon DR dual chamber cardioverter-defibrillator (ICD). Two years later she was found to be in atrial fibrillation and anticoagulated with warfarin. Three years after the ICD was implanted, it delivered a...

BACKGROUND Coronary artery disease (CAD) patients are at risk for life-threatening ventricular arrhythmias (VA) related to scar tissue. Late gadolinium enhancement cardiovascular magnetic resonance (LGE-CMR) can accurately identify myocardial scar extent. It has been shown that scar extent, particularly scar transmurality, percent scar and scar mass, are associated with the occurrence of approp...

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...

Subcutaneous implantable cardioverter defibrillators (S-ICD) are safe and effective for the prevention of sudden cardiac death. To compare safety efficacy S-ICD with transvenous (TV) ICD. Database search was performed all RCTs and/or propensity score-matched (PSM) studies comparing against TV-ICD. The primary outcome lead-related complications. Secondary outcomes included device-related complic...

BACKGROUND Device implant pocket hematoma is a recognized complication after permanent pacemaker (PM) and implantable cardioverter-defibrillator (ICD) implantation. Pocket hematoma is associated with local discomfort, an increased risk of infection, and may require surgical intervention or lead to lengthier hospital stays. The purpose of the study was to identify the clinical factors associated...
