OBJECTIVES The goal of this study was to examine the relative impact of QRS morphology and duration in echocardiographic responses to cardiac resynchronization therapy (CRT) and clinical outcomes. BACKGROUND At least one-third of all patients treated with CRT fail to derive benefit. Patients without left bundle branch block (LBBB) or patients with smaller(More)
AIM In analogy with sepsis, current post-cardiac arrest (CA) guidelines recommend to target mean arterial pressure (MAP) above 65 mmHg and SVO2 above 70%. This is unsupported by mortality or cerebral perfusion data. The aim of this study was to explore the associations between MAP, SVO2, cerebral oxygenation and survival. METHODS Prospective,(More)
BACKGROUND Post-cardiac arrest (CA) patients are at risk of secondary ischemic damage in the case of suboptimal brain oxygenation during an ICU stay. We hypothesized that elevated central venous pressures (CVP) would impair cerebral perfusion and oxygenation (venous cerebral congestion). The aim of the present study was to investigate the relationship(More)
Bilateral visual impairment, associated with amenorrhea, diabetes insipidus and mental deterioration were observed in a 28 year old woman. CT scan revealed bilateral symmetrical infiltrative processes surrounding the ventricular system, which was confirmed by postmortem examination. Histologically the lesion was a germinoma.
The images obtained by computed tomography constitute a new and interesting approach to lesions of the craniovertebral region. The criteria of basilar invagination must be systematically checked in routine examination. The main interest of CT scanning is the simultaneous view of the bony structures as well as the central nervous system in a completely(More)
The CT features of cerebellar lesions with von Hippel-Lindau's disease are analyzed. The use of CT scanning for associated spinal hemangioblastomas is discussed in the light of a case with a low cervical lesion. The role of computed tomography in the neuroradiological investigations is discussed.
The use of coronal tomograms for CT scanning of the orbits is emphasized and the technic for patient positioning is described. Normal tomographic images are described and the contribution of coronal scans to a correct diagnosis is stressed in the light of 16 pathological cases. Coronal tomograms are especially valuable to show the regions of the orbital(More)
