Left ventricular (LV) function may be impaired by right ventricular (RV) apical pacing. The interventricular septum is an alternative pacing site, but randomized data are limited. Our aim was to compare ejection fraction (EF) resulting from pacing the interventricular septum versus the RV apex. RV lead implantation was randomized to the apex or the...

This paper reports the results of a preliminary study evaluating the feasibility and performance of a first whole body hybrid PET/MR scanner allowing sequential acquisition of co-registered MR and PET images. Sixty-two patients underwent whole body PET/MR imaging immediately after a clinical PET/CT. The hybrid device consists of a 3T MR and a time-...

Predicting response to cardiac resynchronization therapy (CRT) remains a challenge. We evaluated the role of baseline QRS pattern to predict response in terms of improvement in biventricular ejection fraction (EF). Consecutive patients (pts) undergoing CRT implantation underwent radionuclide angiography at baseline and at mid-term follow-up. The re...

Titre : Nouvelles dimensions dans l'apprentissage interactif de l'anatomie radiologique Introduction : En général les médecins praticiens et les professionnels de la santé ont peu accès à l’anatomie dans leur pratique clinique alors que ces notions d’anatomie deviennent de plus en plus importantes aujourd’hui étant donné la place prépondérante pri...

Purpose: To measure changes in FDG uptake in different organs at two different points in time to assess variability of SUV measurements in two consecutive PET studies performed about one hour apart. Methods and Materials: In the process of evaluation of a new hybrid PET-MR scanner two consecutive PET scans were obtained after injection of FDG in 48...

Summary Background: Diagnosis of ventricular dyssynchrony may play a role in patient selection for cardiac resyn- chronisation therapy. Various imaging techniques are available for diagnosis of dyssynchrony, including echocardiography and radionuclide imaging. Whether these techniques yield concordant results is not known. Methods: We studied 31 pa...

The effect of cardiac resynchronization therapy (CRT) on right ventricular ejection fraction (RVEF) has not been well studied. Furthermore, it is unclear whether baseline RVEF influences response to CRT. To evaluate the acute and chronic effects of CRT on right ventricular systolic function, and to investigate whether baseline RVEF impacts response...

Measurement of left ventricular ejection fraction (LVEF) using real time 3D echocardiography (3DE) has been performed in subjects with preserved or modestly reduced systolic function. Our aim was to evaluate this technique in the subset of patients with severe systolic dysfunction. Consecutive patients with LVEF less than 0.35 at two-dimensional ec...

COMPARAISON DE LA FONCTION VENTRICULAIRE GAUCHE MESUREE PAR TEMP, TEP ET TDM CHEZ LE PATIENT CORONARIEN Introduction Nous avons choisi d’établir la validité des mesures de la fraction d’éjection du ventricule gauche (FEVG) obtenues par TEP synchronisée et de les comparer aux mesures obtenues par TDM et TEMP chez le patient coronarien atteint de d...

Purpose The validity of measures of left ventricular (LV) function from cardiac gated PET and CT assessment is not well established. To support feasibility, we compared the global left ventricular ejection fraction (LVEF) from gated PET and CT with gated SPECT using the QGS® software package approved method for LVEF calculation in myocardial perfu...

To assess changes in cardiac adrenergic activity with cardiac resynchronization therapy (CRT), and to investigate whether these changes are related to improvement in left ventricular ejection fraction (LVEF). Sixteen patients (13 males, age 66 +/- 7 years) were studied at baseline and after > or =6 months of CRT (mean follow-up 9.2 +/- 3.2 months)....

Purpose Our goal was to determine if left ventricular ejection fraction (LVEF) calculated from gated PET images correlates with EF obtained from MDCT images and would therefore be applicable to cardiac PET/CT in patient with severe renal insufficiency who cannot get contrast injection. Materials and Methods Thirty patients with LV dysfunction and m...

Backgound: Ventricular dyssynchrony is often measured by tissue Doppler imaging (TDI), which assesses wall motion of a limited number of wall segments and over a single heart beat. Radionuclide angiography with nuclear phase analysis (NPA) can be used to quantify dyssynchrony of the entire ventricles, with data that are averaged over several minute...

The identification of patients with a significant proximal right coronary artery (RCA) is of clinical relevance since it may direct diagnostic and therapeutic strategies. This study was performed to determine parameters of (201)Tl RV perfusion SPECT which can be used to discriminate between proximal and distal RCA stenosis in patients with inferior...

Biventricular pacemakers are usually programmed with the default setting of synchronous biventricular pacing, although the ventricles may be paced sequentially. Whether this parameter is important for optimizing resynchronization therapy is not clear. The purpose of this study was to investigate whether sequential pacing acutely improves left ventr...

Although several myocardial iodine 123 metaiodobenzylguanidine (MIBG) indices are increasingly used to detect alterations in myocardial sympathetic activity in various forms of cardiac pathology, published measurements of normal values and within-subject variability are lacking. Twenty-five healthy volunteers underwent planar and single photon emis...

Background: [123I]-meta-iodobenzylguanidine (MIBG) scintigraphy can be used to assess cardiac sympathetic activity which is related to severity and prognosis in heart failure. Although cardiac MIBG scintigraphy is increasingly used to monitor the effect of therapeutical interventions, normal values and within-subject variability are lacking. Theref...

The tomographic mode has replaced the planar mode for radióisotopic studies of myocardial perfusion but not for the study of systolic ventricular function. The aim of this study was to compare monophotonic emission tomography (MPET), the planar mode (PM) and contrast angiography (Angio). The left ventricular volumes and ejection fractions were meas...
