INDICATIONS The majority of ERNA studies are performed for assessment of LV volume and function at rest, with serial evaluation for monitoring of medical or surgical therapy, or to diagnose chemotherapy-associated cardiotoxicity (Table 1). In general
Equilibrium radionuclideangiography compared with tissue doppler imaging for detection of right ventricular dyssynchrony and prediction of acute response to cardiac resynchronization therapy. The aim of this study was to compare tissue doppler imaging (TDI) and equilibrium radionuclideangiography (ERNA) for detection of right ventricular (RV) dyssynchrony and prediction of the acute response
Right ventricular functional analysis utilizing first pass radionuclideangiography for pre-operative ventricular assist device planning: a multi-modality comparison Advanced heart failure treated with a left ventricular assist device is associated with a higher risk of right heart failure. Many advanced heart failures patients are treated with an ICD, a relative contraindication to MRI, prior to assist device placement. Given this limitation, left and right ventricular function for patients with an ICD is calculated using radionuclideangiography utilizing planar multigated acquisition (MUGA) and first pass radionuclideangiography (FPRNA), respectively. Given the availability of MRI protocols that can accommodate patients with ICDs, we have correlated the findings of ventricular functional
Utility of Equilibrium RadionuclideAngiogram-Derived Measures of Dyssynchrony to Predict Outcomes in Heart Failure Patients Undergoing Cardiac Resynchronization Therapy. undefined Sixty-six advanced heart failure patients referred for CRT with an LV ejection fraction (EF) of < 35% and QRS ≥ 120 ms were studied. We performed equilibrium radionuclideangiography (ERNA) before and 6 mo after CRT
Comparison of radionuclideangiographic synchrony analysis to echocardiography and magnetic resonance imaging for the diagnosis of arrhythmogenic right ventricular cardiomyopathy. Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a heritable arrhythmia syndrome entailing a high risk of sudden cardiac death. Discernment from benign arrhythmia disorders, particularly right ventricular outflow tract ventricular tachycardia (RVOT VT), may be challenging, providing an impetus to explore alternative modalities that may facilitate evaluation of patients with suspected ARVC. We evaluated the role of equilibrium radionuclideangiography (ERNA) as a diagnostic tool for ARVC. ERNA measures of ventricular synchrony-synchrony (S) and entropy (E)-were examined in patients with ARVC (n = 16
Evaluation of Whole-body CZT Camera in Gated Tomographic RadionuclideAngiography Tomographic radionuclideangiography (or blood pool) is a reproducible method to evaluate left ventricular ejection fraction that is needed during oncological treatments or to evaluate cardiopathies.Cardiac-dedicated CZT systems allowed dose or time reduction. Multipurpose CZT cameras have not yet been evaluated in this indication. Moreover, the impact of attenuation correction is not known. Tomographic radionuclideangiography is a simple, rapid and reproducible method of cardiac function measurement, including left (LVEF) and right (RVEF) ventricular ejection fractions.In addition to cardiological indications, this examination is often performed as part of cardiac toxicity screening during the various oncological
Equilibrium radionuclideangiography for evaluating the effect of facilitated percutaneous coronary intervention on ventricular synchrony in patients with acute myocardial infarction. It is unclear whether facilitated percutaneous coronary intervention (PCI) via a transradial approach therapy is preferable to primary PCI, with improved ventricular synchrony performance (VS), in Chinese patients . The 152 patients with their first anterior acute myocardial infarction (AMI) were randomized to a primary PCI group or facilitated PCI group. In the 1(st) week and 6(th) month after AMI onset, the parameters of VS were measured by equilibrium radionuclideangiography with ventricular phase analysis. The rate of TIMI grade-3 flow in the infarct-related artery pre-PCI in the facilitated PCI group
Right ventricular systolic function for risk stratification in patients with stable left ventricular systolic dysfunction: comparison of radionuclideangiography to echoDoppler parameters. Previous studies have demonstrated that the radionuclide right ventricular (RV) ejection fraction (RVEF), tricuspid annular plane systolic excursion (TAPSE), and tissue Doppler peak systolic tricuspid annular evaluation (clinical data, biological data, radionuclideangiography, echoDopplercardiography, cardiopulmonary exercise test). Tricuspid annular plane systolic excursion and STr were weakly correlated with RVEF (r = 0.20). During a follow-up period of 1268 days (802-1830), there were 121 cardiovascular deaths. Best cut-off values were 37%, 9.7 cm/s, and 18.5 mm for RVEF, STr, and TAPSE, respectively. Right

Normal LVEF is approximately 60%. Management of HF is based upon
initiation of oncologic therapy in the setting of cardiac symptoms. Nuclear Medicine Ventriculography Radionuclide ventriculography, also known as multigated radionuclideangiography, has been commonly used for the assessment of LVEF with good accuracy and reproducibility [20]. However, a recent study of 75 patients with cancer comparing radionuclide ventriculography EFs and cardiac MRI demonstrated
scintigraphy allows for the assessment of differential pulmonary blood flow in patients with TOF and branch pulmonary artery stenosis or hypoplasia [12]. SPECT/CT MPI Rest and Stress Radionuclideangiography may be performed to assess LV function but has been replaced by MRI in this setting. Its use to assess RV function is limited by the confounding effect of counts from other chambers. In addition
