The benefit of implantable cardioverter-defibrillator (ICD) therapy depends upon appropriate evaluation of a persisting risk of sudden death and estimation of the patient's overall survival. Assessment of a stable and unchangeable arrhythmogenic substrate is often difficult. Structural abnormality and ventricular dysfunction, the two major risk parameters, may recover, and heart failure symptom...
OBJECTIVES We hypothesized that reductions in left atrial volume (LAV) with a cardiac resynchronization therapy-defibrillator (CRT-D) would translate into a subsequent reduction in the risk of atrial tachyarrhythmias (AT). BACKGROUND There is limited information regarding the effect of CRT-D on the risk of AT. METHODS Percent reduction in LAV at 1 year following CRT-D implantation (pre-spec...
BACKGROUND Implantable cardioverter-defibrillator indications in Brugada syndrome remain controversial, especially in asymptomatic patients. Previous outcome data are limited by relatively small numbers of patients or short follow-up durations. We report the outcome of patients with Brugada syndrome implanted with an implantable cardioverter-defibrillator in a large multicenter registry. METH...
The traditional transvenous defibrillator has been one of the greatest advancement in Cardiology in the last 30 years and has demonstrated to reduce arrhythmic and total mortality in selected patients. However the traditional defibrillator can have a high price to pay in terms of complications, the "weakest link" being the transvenous/endocardial leads. The entirely subcutaneous defibrillator (...
Sir, As arrhythmias occur when thrombolytics are administered, it is advised by Rawles (editorial, April Journal, p.l71) and by Hannaford and colleagues (April Journal, p.175) and elsewhere' that every doctor carrying thrombolytics outside hospital should also carry a defibrillator. I was not aware of this in 1992 when I considered participating in Hannaford and colleagues' study and it is not ...
Coagulase-negative staphylococci and Staphylococcus aureus are the commonest pathogens involved in infections of pacemaker-defibrillator systems. Among causative Gram-negative bacteria, infections due to Klebsiella, Serratia, Pseudomonas, Acinetobacter and other species have been reported. We report herein a unique case of an automatic implantable cardioverter defibrillator infection due to Pro...
An increasing number of patients have a coexisting implantable cardioverter defibrillator (ICD) and left ventricular assist device (LVAD) to treat ventricular arrhythmias and refractory heart failure, respectively. To date, there have been no published reports of negative interactions between these devices that have impacted appropriate ICD or LVAD function. In this case report, we describe a p...
OBJECTIVE Although sudden cardiac death is rare in children, an intracardiac defibrillator system is indicated in children with various types of cardiomyopathy, primary electrical diseases, and after surgical repair of congenital heart defects. The use of transvenous defibrillator lead systems is limited in pediatric patients because of a small body size and/or limited vascular access. Subcutan...
BACKGROUND Management of antithrombotic agents after implantable cardioverter defibrillator implantation is challenging, particularly among patients with atrial fibrillation and coronary artery disease. METHODS AND RESULTS Using data from National Cardiovascular Data Registry(®) Implantable Cardioverter Defibrillator Registry(™) linked with Medicare claims data, we identified 25 180 patients ...
A pacemaking system consists of an impulse generator and lead or leads to carry the electrical impulse to the patient's heart. Pacemaker and implantable cardioverter defibrillator codes were made to describe the type of pacemaker or implantable cardioverter defibrillator implanted. Indications for pacing and implantable cardioverter defibrillator implantation were given by the American College ...
