AIMS Previous studies on biventricular (BIV) pacing and cardiac resynchronization therapy-defibrillator (CRT-D) efficacy have used arbitrarily chosen BIV pacing percentages, and no study has employed implantable cardioverter defibrillator (ICD) patients as a control group. METHODS AND RESULTS Using Kaplan-Meier plots, we estimated the threshold of BIV pacing percentage needed for CRT-D to be ...

The implantable cardioverter-defibrillator (ICD) has become a cornerstone in the prevention of sudden cardiac death in patients with ischaemic and non-ischaemic cardiomyopathy, as well as in survivors of idiopathic ventricular arrhythmias and carriers of a genetic arrhythmia syndrome. Current guidelines recommend ICD implantation in patients with a left ventricular ejection fraction 35%, despit...

Background—Outcome data for patients receiving implantable cardioverter-defibrillator (ICD) and cardiac resynchronization therapy– defibrillator (CRT-D) devices treated outside of clinical trials are lacking. No clinical trial has evaluated mortality after device implantation or after shock therapy in large numbers of patients with implanted devices that regularly transmit device data over a ne...

Cardiac sarcoidosis is a rare complication of pulmonary sarcoidosis, causing granulomatous inflammation the myocardium, ultimately resulting in infiltrative cardiomyopathy. Through fibrotic inflammation, cardiac predisposes patients to multiple complications, such as conduction abnormalities, ventricular arrhythmias, heart failure, and sudden death. Due adverse prognosis abnormalities these pat...

P lease implant a defibrillator in my patient, read the letter from the referring physician. "He was resuscitated from a cardiac arrest resulting from ventricular fibrillation. He had no myocardial infarction, and he has no evidence of acute ischemia, although he has extensive inoperable coronary artery disease." The implantable cardioverter-defibrillator (ICD) is one of the most revolutionary ...

background: permanent pacemakers provide effective relief of symptoms and are life-saving in patients with symptomatic heart block. implantable cardioverter defibrillators (icd) are also increasingly recognized as life-saving tools in various groups of patients with malignant ventricular tachyarrhythmias. methods: as part of the “world survey on pacemaker and icd implantations”, a survey of all...

BACKGROUND The implanted cardioverter defibrillator (ICD) improves survival in high-risk cardiac patients. This analysis from the MADIT-II trial database examines the long-term clinical course and subsequent mortality risk of patients after termination of life-threatening ventricular tachyarrhythmias by an ICD. METHODS AND RESULTS Life-table survival analysis was performed, and proportional h...

Implantable cardioverter defibrillator (ICD) can be a crucial therapeutic modality for pediatric patients with congenital heart disease, Brugada syndrome, long QT syndrome and cardiomyopathy. Because transvenous implantation of ICD is mostly unfeasible for pediatric patients due to anatomical and technical limitations, epicardial patch type or subcutaneous type ICD have been used. Implantation ...

AIMS The primary aim of this retrospective study was to determine the proportion of patients with myocardial infarction (MI) who fulfil the criteria of the Multicenter Automatic Defibrillator Implantation Trial (MADIT) II and the implications of MADIT II criteria in practice. METHODS We performed a retrospective analysis of three hundred and ninety four admissions to the Coronary Care Unit (C...
