Rate, Time Course, and Predictors of Implantable Cardioverter Defibrillator Infections: An Analysis From the SIMPLE Trial.

Background: The number of implantable cardioverter defibrillator (ICD) infections is increasing due to an increased number of ICD implants, higher-risk patients, and more frequent replacement procedures, which carry a higher risk of infection. Reducing the morbidity, mortality, and cost of ICD-related infections requires an understanding of the current rate of this complication and its predictors.

Methods: The hock ant valuation Trial (SIMPLE) trial randomized 2500 ICD recipients to defibrillation testing or not.

[Interruption of cardiac resynchronization therapy after a ventricular premature beat : What is the mechanism?].

The present case report illustrates a mechanism that can interrupt cardiac resynchronization therapy (CRT) and lead to recurrence of dyspnea during exercise. It points out that CRT requires a regular cardiac history, analysis of device-stored data and profound knowledge about function and especially timing intervals of these systems in order to utilize the full potential of this therapy.

Effectiveness of a percutaneous left ventricular assist device in preventing acute hemodynamic decompensation during catheter ablation of ventricular tachycardia in advanced heart failure patients: A retrospective single-center analysis.

Introduction: Acute hemodynamic decompensation during catheter ablation of ventricular tachycardia is associated with increased mortality. We assessed the effectiveness of mechanical circulatory support using a micro-axial percutaneous assist device in preventing acute hemodynamic decompensation.

Methods And Results: Twenty-six consecutive patients with structural heart disease undergoing 28 ventricular tachycardia ablations between May 2013 and October 2017 were included.

Effectiveness of single- vs dual-coil implantable defibrillator leads: An observational analysis from the SIMPLE study.

Introduction: Dual-coil leads (DC-leads) were the standard of choice since the first nonthoracotomy implantable cardioverter/defibrillator (ICD). We used contemporary data to determine if DC-leads offer any advantage over single-coil leads (SC-leads), in terms of defibrillation efficacy, safety, clinical outcome, and complication rates.

Methods And Results: In the Shockless IMPLant Evaluation study, 2500 patients received a first implanted ICD and were randomized to implantation with or without defibrillation testing.
