OBJECTIVES: Clinical difficulty to discriminate between the Alzheimer disease (AD) and dementia with Lewy bodies (DLB) has led researchers to focus on highly sensitive functional imaging modalities. The aim of the present study was to assess (131)I-MIBG cardiac imaging to distinguish between AD and DLB. PATIENTS AND METHODS: Seventeen patients who were known cases of dementia underwent (131)I-MIBG myocardial scintigraphy to differentiate AD from DLB. Planar and (131)I-MIBG SPECT were obtained 2h after the injection of 1mCi (131)I-MIBG on a dual head gamma camera...

Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital heart disease usually diagnosed during the first months of life. Without surgical treatment, ALCAPA carries a high mortality risk, and disease presentation in adulthood is rare. We describe the diagnosis and management of patients presenting with ALCAPA in adulthood. This multicenter French nationwide retrospective study included adult patients diagnosed from 1980 to 2014. Eleven adult patients (mean age: 38 ± 17 years) were analyzed...

Background: Selegiline enhances the patient's endogenous dopamine by inhibiting dopamine metabolism. The efficacy of selegiline monotherapy for drug-naïve Parkinson's disease (PD) patients may depend on the degree of dopaminergic neuronal degeneration. (123)I-Ioflupane single photon emission computed tomography (SPECT) and (123)I-meta-iodobenzylguanidine (MIBG) myocardial scintigraphy are diagnostic methods to assess the pharmacological and pathological changes in PD. Objective: We examined the utility of these imaging methods to predict the efficacy of selegiline monotherapy for motor symptoms in drug-naïve PD patients...

A 76-year-old man who had been diagnosed with long-QT syndrome type 2 had frequent syncopal attacks. The electrocardiogram was monitored, and frequent torsades de pointes (TdP) was detected despite administration of conventional medications: oral propranolol, verapamil, intravenous magnesium sulfate, verapamil, and lidocaine. In contrast, 2 μg/kg/min landiolol could completely suppress TdP. Subsequently, an implantable cardioverter defibrillator was placed, and he was diagnosed with silent myocardial ischemia using myocardial perfusion scintigraphy and coronary angiography...

REVIEW
Babak Tousi
Proper diagnosis of dementia with Lewy bodies (DLB) in clinical practice remains suboptimal as many cases are misdiagnosed, usually as Alzheimer disease (AD) or Parkinson's disease (PD) and, in rare cases, psychosis. Therefore, it is important for patients with dementia to be thoroughly evaluated by a specialist who is familiar with current diagnostic tests and treatment options. New diagnostic criteria from the Dementia with Lewy Bodies Consortium have been developed to increase diagnostic sensitivity for DLB (Diagnosis and management of dementia with Lewy bodies: fourth consensus report of the DLB Consortium; McKeith et al...

The objective of this study was to systematically investigate cardiac and peripheral vasomotor autonomic functions in late-onset transthyretin Val30Met familial amyloid polyneuropathy (FAP ATTR Val30Met) patients from non-endemic areas. The coefficient of variation of R-R intervals (CVR-R), responses to the Valsalva manoeuvre, head-up tilt test with impedance cardiography, noradrenaline infusion test, and (123)I-metaiodobenzylguanidine (MIBG) myocardial scintigraphy were assessed in eight patients. Although only four patients manifested orthostatic hypotension during the head-up tilt test, CVR-R, responses to the Valsalva manoeuvre, and myocardial MIBG uptake indicated a higher prevalence of cardiac sympathetic and parasympathetic dysfunction...

BACKGROUND: There is a consensus that overactivation of the cardiac sympathetic nervous system (CSN) proportionately increases the severity of heart failure and is accompanied by worse prognosis. Because it is unknown whether patients with aortic valve stenosis (AS) have similar CSN activation, we investigated the effect of transcatheter aortic valve implantation (TAVI).Methods and Results:We enrolled 31 consecutive patients with AS treated by TAVI. (123)I-metaiodobenzylguanidine (MIBG) myocardial scintigraphy was performed at baseline and at 2 weeks after TAVI...

The definition, presentation, and management of myocardial infarction (MI) have changed substantially in the last decade. Whether these changes have impacted on the presence, severity, and localization of necrosis at myocardial perfusion imaging (MPI) has not been appraised to date. Subjects undergoing MPI and reporting a history of clinical MI were shortlisted. We focused on the presence, severity, and localization of necrosis at MPI with a retrospective single-center analysis. A total of 10,476 patients were included, distinguishing 5 groups according to the period in which myocardial perfusion scintigraphy had been performed (2004 to 2005, 2006 to 2007, 2008 to 2009, 2010 to 2011, 2012 to 2013)...
