Hydrocephalus communicating with the basilar subarachnoid cisterns may manifest itself as enlargement of these spaces. Confirmation of this finding is based on resolution of dilatation after ventricular shunting. A series of eight patients points out the CT characteristics, the differential diagnosis, and the importance of the cisternal ventricle in the transmission of CSF.

The angiocardiographic, echocardiographic, and, where available, the necropsy findings were correlated in 32 cases of primitive ventricle. Single probe echocardiography was shown to be a reliable and accurate technique for diagnosis of primitive ventricle; the ventricular and atrioventricular valve appearances were characteristic, and the outlet chamber was usually recognised when present, thou...

Single ventricle is that condition in which both atrioventricular (A-V) orifices enter a common ventricular sinus, from which the arterial trunks emerge with their coni. The following types of single ventricle were found: (1) with regular (noninverted) transposition in levocardia; (2) with inverted transposition in levocardia; (3) with normal position of arterial trunks in levocardia; (4) in de...

INTRODUCTION Glioblastoma is the most common and the most malignant type of gliomas. Cerebral hemispheres are usual locations for gliomas. Isolated third ventricular presentation is very rare for glioblastomas. A new case of isolated third ventricular glioblastoma has been presented in this report. CASE DESCRIPTION A 36-year-old woman was admitted to outpatient clinic with headache, blurred v...

UNLABELLED Between May 1974 and December 1993, 37 patients (0.75%) with a double-chambered right ventricle underwent surgical repair. The patients ranged in age from 11 months to 12 years (mean 4 +/- 1.1 years). Cardiac catheterization was performed in 36 patients. The proximal right chamber pressure was 118 +/- 10 mmHg and the mean ventricular gradient pressure was 75 +/- 10 mmHg. A ventricula...

Early transmitral flow (MiF) patterns depend strongly on the rate of fall of measured left ventricular pressure (Pm) determined by both the active decay of pressure (Pa) due to myocardial relaxation and the increase in pressure due to stretch of passive elements during filling (Pp). This study was designed to uncouple passive forces from deactivation in order to reveal the instantaneous rate an...

Abnormal development of the arterial pole of the heart underlies a significant fraction of congenital heart defects. Critical steps in arterial pole development are formation of the myocardial outflow tract (or conotruncal region) and its subsequent division into separate left and right ventricular outlets. Division of the cylindrical outflow tract is a complex morphogenetic process driven by c...
