Cardiac 123I-MIBG scintigraphy and arrhythmic risk in left ventricular noncompaction.
Left ventricular noncompaction is an unusual but increasingly recognized cardiomyopathy, the etiology of which is still not definitely established. Clinical presentation includes a wide spectrum of scenarios, including heart failure, thromboembolism and malignant arrhythmias, with half of deaths occurring suddenly. Early detection of LVNC is therefore essential to prevent sudden cardiac death. ...

Iodine-123-metaiodobenzylguanidine ((123)I-MIBG) scintigraphy is a nuclear medicine technique which describes the functional status of the cardiac sympathetic nervous system. It is well known that an autonomic dysfunction is present in heart failure setting as a neuronal uptake of norepinephrine is impaired in the failing myocardium. Reduction in sympathetic nervous function in the heart, measu...
متن کاملThe utility of ADMIRE-HF risk score in predicting serious arrhythmic events in heart failure patients: incremental prognostic benefit of cardiac 123I-mIBG scintigraphy.
BACKGROUND A minority of heart failure (HF) patients who undergo implantable cardioverter defibrillator (ICD) implantation for primary prevention of sudden cardiac death (SCD) receive device therapy. Whether the addition of mIBG scintigraphy to conventional markers of arrhythmic risk can provide incremental risk stratification in HF patients has not been investigated. METHODS We identified 77...
متن کامل‘ICD in Primary Prevention: Potential Role of Sympathetic Nerve Imaging’
Patients with chronic heart failure (CHF) and left ventricular ejection fraction (LVEF) ≤ 35% are at increased risk for sudden cardiac death (SCD). These patients are likely to receive an implantable cardioverter defibrillator (ICD), effective in reducing the occurrence of SCD in primary prevention. The decision to use an ICD in CHF, according to the current guidelines, is based on New York Hea...
متن کاملImprovement of cardiac function and neurological remodeling in a patient with tachycardia-induced cardiomyopathy after catheter ablation.
Incessant ventricular tachycardia and long-standing ectopic beats lead to tachycardia-induced cardiomyopathy. Catheter ablation eliminates ventricular tachycardia and reverses left ventricular (LV) dysfunction. 201-Thallium ((201)Tl) scintigraphy demonstrates perfusion defects with ischemic cardiomyopathy. Reversible perfusion defects are observed even in non-ischemic cardiomyopathy, related to...
