Atresia of the lateral ventricle.

Single Ventricle with Mitral and Aortic Atresia

Congenital cardiovascular malformations occur in about 5 to 8 of every 1,000 live births, and the percentage in stillborn infants is probably even higher. Between the 5 and 8 weeks of embryonic life, the primitive heart tube undergoes a process of folding, remodeling with the formation of valves, and septation that transforms its single lumen into the four chambers of the definitive heart. Alth...

Aortic atresia with normal sized left ventricle

Aortic atresia with an associated ventricular septal defect and adequate sized left ventricle is extremely rare. We present two cases in which an alternate diagnosis was suggested on echocardiography because the hypoplastic aortic trunk was missed due to its small caliber. The final diagnosis was, however, clinched on dual source computed tomography, which not only showed the thin aortic trunk ...

P81: Psychosocial Stress of Maternal Deprivation Enhanced Volume of Lateral Ventricle in Rat Brain

Brain areas implicated in the stress response include the amygdala, hippocampus and prefrontal cortex. Neonatal stimulation of an animal by handling or by enhanced maternal care induces at adult age a decrease of the hypothalamo-pituitary adrenal (HPA) response to stressors, a decrease of anxiety in a novel environment, and neuroanatomical changes. In this present study we demonstrated that mat...

Pedunculated gliomas in the lateral ventricle.

Coexistence of single ventricle with atresia of one atrioventricular orifice.

SUMMARY A new case of an unusual association of mitral atresia with single left ventricle is reported. The salient anatomic features include: (1) the right atrioventricular valve is atretic; (2) the left atrioventricular valve enters the large ventricle with morpho-logic characteristics of the left ventricle; and (3) this large ventricle communicates by way of an interventricular communication ...
