• Different Growth Factor Activation in the Right and Left Ventricles in Experimental Volume Overload .
• The present study was performed to investigate whether a different growth factor response is activated in the right and left ventricles in aortocaval fistula and its effects on regional myocardial adaptation. ... The left and right ventricles respond differently to aortocaval fistula, and local growth factor expression is closely related to the regional myocardial adaptation. ...

• The Ventricles contain a vascular membrane, the Choroid Plexus, that secretes CerebroSpinal Fluid. The Lateral Ventricles communicate with the cavity of the DienCephalon, the midline Third Ventricle, by way of InterVentricular Foramina.
• Its narrow cavity, the Cerebral Aqueduct connects the Third and Fourth Ventricles.
• The Ventricles Of The Brain.
• The Ventricles contain a vascular membrane, the Choroid Plexus, that secretes CerebroSpinal Fluid.
• The Lateral Ventricles communicate with the cavity of the DienCephalon, the Midline Third Ventricle, by way of the InterVentricular Foramina.
• In the MidBrain, the narrow Cerebral Aqueduct connects the Third and Fourth Ventricles.
• It is elaborated by or through the Choroid Plexuses of the Lateral, the Third and the Fourth Ventricles of the Brain.
• It occupies the InterCommunicating Ventricles and, being constantly formed, is drained from the Ventricles by minute Foramina in the roof of the Fourth Ventricle.

• © 1982 The Royal College of Psychiatrists Normal ventricles in young schizophrenics.

• You should be able to identify the four chambers of the pigs heart externally: the right and left atria(singular: atrium) and right and left ventricles. ...
•   The division between the right and left ventricles can be seen externally bythe location of a prominent groove termed the coronary sulcus that is also the path the coronary.

• Postoperative Cerebral Edema Occurring in Children With Slit Ventricles .
• Slit ventricles (SV) are collapsed or abnormally small ventricles apparent on computed tomographic (CT) or magnetic resonance imaging (MRI) scans after insertion of a ventricular shunt in a patient with hydrocephalus. ...
•   Computed tomographic scans at the level of the lateral ventricles in Case 1 show A, slit ventricles 1 year preoperatively, and B, further compresson of the ventricles with cerebral edema 22 hours postoperatively. ...
• 10 Thus, with a very compliant brain and little pressure to keep the ventricles open after shunt insertion, ventricular collapse may occur. ...
• The compliance of the growing infant brain with a shunt in place may then start to significantly decrease as myelination occurs and chronic scar formation begins to develop around narrowed ventricles. ... 10,11,13 Thus, the hydrocephalic brain with a shunt in place, especially when inserted at a young age, may have small, scarred, slit-like ventricles with limited drainage capability and very little compliance. ...
• SV, slit ventricles. ...
• Dahlerup B, Gjerris F, Harmsen A, Sørensen P Severe headache as the only symptom of long-standing shunt dysfunction in hydrocephalic children with normal or slit ventricles revealed by computed tomography. ...

• The heart has two ventricles, the right ventricle and the left ventricle. ...

• Mechanisms of differential growth of heart ventricles in newborn pigs.

• Development of the heart: (2) Septation of the atriums and ventricles .
• Keywords: heart development; septation; atriums; ventricles.
• In this second review, we discuss the processes that complete the separation of the two sides of the definitive heart, for the most part involving septation of the parts of the primary tube not themselves directly involved in formation of the chamber-specific compartments of the atriums and ventricles. ...
• The cushions are also adherent to the crest of the muscular ventricular septum, this septum itself forming as the apical trabecular components of the developing left and right ventricles balloon from the primary heart tube (see below). ...
• As explained in our first review,1 the muscular part of the ventricular septum is produced concomitant with the ballooning of the apical components of the right and left ventricles from the primary heart tube. ...
• Ballooning of the apical parts of the right and left ventricles from the ascending and descending parts of the ventricular component of the primary heart tube, respectively, has produced the primary muscular ventricular septum between them (star). ...
• These studies13,23 showed unequivocally that the primary muscular ventricular septum produced by ballooning from the primary heart tube separated not only the apical components of the ventricles, but also interposed between the entirety of the inlet of the right ventricle and the cavity of the left ventricle. ...
• Thus, as the apical parts of the ventricles balloon from the primary heart tube, the antibody to the nodose ganglion delimits a band of tissue that surrounds the primary interventricular foramen (fig 19). ... Subsequent to formation of the inlet of the right ventricle, therefore, the primary muscular ventricular septum separates the entirety of the cavities of the ventricles. The additional step then required to permit closure of the embryonic interventricular foramen, separating completely the newly formed right and left ventricles, is the "transfer" of the subaortic outlet to the left ventricle. ...

• Tbx5 specifies the left/right ventricles and ventricular septum position during cardiogenesis .
• Vertebrates exhibit different heart morphologies: fish have one ventricle/one atrium, whereas birds and mammals have two ventricles/two atria. ...
• This expression pattern strongly suggests that Tbx5 specifies the identity of the left and right ventricles and that the ventricular septum is formed at the boundary of Tbx5-positive and -negative regions (black arrowhead in Fig. ...
• The ventricular septum is formed at the boundary of the two areas (arrowheads, A,B) that give rise to the left and right ventricles. ... 5 (C) and GATA4 (D) is observed throughout the developing heart ventricles. ...
• These observations strongly suggest that the right and left ventricles are specified by the distinct Tbx genes expressed in an asymmetric fashion. ...
• 5 and GATA4 genes, are expressed ubiquitously in the developing heart ventricles (Fig. ...
• 1J indicates the boundary between the left and right ventricles. ...
• In the normal heart, the ventricular septum formed at the boundary of the left and right ventricles (Fig. ... At this stage, extensive trabecular formation was also evident in both the right and left ventricles that are connected to the pulmonary artery and aorta, respectively (Fig. ...
• The pulmonary artery and aorta are connected to the right and left ventricles, respectively. Both right and left ventricles develop normally with the extensive trabecular formation and a ventricular septum. ... The relative sizes of these two ventricles indicate a shift of the ventricular septum formation to the right, although the trabecular formation and the thickness of ventricles were not affected. ...
• The relative sizes of the two ventricles suggested that the ventricular septum was shifted to the right. ...
• Nonetheless, in the chick heart, other markers such as the dHAND and eHAND genes are expressed uniformly in both ventricles (data not shown). ...
• By contrast, dHAND genes is predominantly expressed in the prospective right, albeit expanding to the bulbus cordis, the part of the prospective left ventricles and the ventricular septum (Fig. ... Hence these three genes provide good markers to confirm the identity of the left and right ventricles. ...

• Tbx5 specifies the left/right ventricles and ventricular septum position during cardiogenesis .

• Prevalence of hibernating myocardium in patients with severely impaired ischaemic left ventricles .
• ConclusionIt is possible that up to 50% of patients with ischaemic heart disease and severely impaired left ventricles have hibernating myocardium.
• We have, therefore, used PET to study the prevalence of hibernating myocardium in a consecutive series of patients undergoing coronary angiography, who have coronary artery disease and severely impaired left ventricles. ...
• Prevalence of hibernating myocardium in patients with severely impaired ischaemic left ventricles.
