The Potential Role of Iodine-123 Metaiodobenzylguanidine Imaging for Identifying Sustained Ventricular Tachycardia in Patients with Cardiomyopathy
Implantable cardioverter-defibrillators (ICDs) significantly reduce mortality in patients with depressed left ventricular ejection fraction (LVEF) and heart failure (HF). However, shortcomings of LVEF to accurately identify those at greatest risk of ventricular tachyarrhythmias have led to the pursuit of alternative means to refine qualification criteria for ICD implantation. It is well establi...

Patients with congenital heart disease and a systemic ventricular ejection fraction less than 30% should undergo prophylactic implantation of an implantable cardioverter defibrillator.
Areduced left ventricular (LV) ejection fraction (EF) is established as one of the strongest risk factors for sudden and total cardiac mortality in adults with ischemic and nonischemic heart disease.1,2 Based on the Multicenter Automatic Defibrillator Implantation Trial II and Sudden Cardiac Death in Heart Failure Trial (SCD-HeFT) clinical trials, patients with an LVEF 30% are at a significantl...
متن کاملCardiac 123I-MIBG Imaging for Clinical Decision Making: 22-Year Experience in Japan.
Cardiac neuroimaging with (123)I-metaiodobenzylguanidine ((123)I-MIBG) has been officially used in clinical practice in Japan since 1992. The nuclear cardiology guidelines of the Japanese Circulation Society, revised in 2010, recommended cardiac (123)I-MIBG imaging for the management of heart failure (HF) patients, particularly for the assessment of HF severity and prognosis of HF patients. Con...

Over 5 million individuals are afflicted with heart failure in the United States per year. [1] Current guidelines based on the MADITI and II, MUSTT and SCDHeFT trials recommend the use of pharmacologic as well as implantable cardioverter defibrillator (ICD) therapy as Class I indications for the prevention of sudden cardiac death (SCD) in a subgroup of patients (depending on their ejection frac...

The importance of neuronal dysfunction in the progression of heart failure and the utility of cardiac sympathetic imaging for identifying ischemic cardiomyopathy patients who are at high risk of sudden cardiac death is well established. On the basis of the results of the ADMIRE-HF (AdreView Myocardial Imaging for Risk Evaluation in Heart Failure) multicenter trial, 123I-meta-iodobenzylguanidine...
