Ventricles

The two chambers of the heart that are involved in pumping blood. The right ventricle pumps blood into the lungs to receive oxygen. The left ventricle pumps blood into the circulation of the body to deliver oxygen to all of the body's organs and tissues.

We show that backpropagation neural network (BPNN) can be employed to learn the robust recognition/classification of left ventricles and nonleft ventricles as positive and negative training examples, respectively.
Because of these peculiar aspects of CD cardiomyopathy, diagnostic tools capable of detecting early myocardial involvement in both ventricles can represent a first step towards an early and effective treatment of these patients before the development of more advanced fibrotic and irreversible changes.
Frontal and temporal horns of lateral ventricles are visible and enlarged.
Caption: Figure 1: (a) Nonenhanced axial section at the level of the foramen of Monro: a well-defined, round, hyperdense lesion causing mild prominence of bilateral lateral ventricles. (b) Contrast enhanced image shows no significant enhancement in the lesion.
During each semester, the students' understanding of the heart is reviewed and one concept covered is the reason for the difference in thickness of the left and right ventricles. The majority of students' explanations appear to be the misconception described above, perpetuated by biology textbooks and science teachers.
Of the total number of epidermoid occurences, there is < 1% incidence of an intraven-tricular epidermoid within the lateral ventricle. (2,3) This entity has been previously reported, but only in an adult patient.
However, conventional CRT devices use wired leads to deliver pacing pulses to the left ventricle.
They usually occur in the anterior and anterosuperior part of the third ventricle [4,5].
In complete heart block, the ventricles contract at about 40 beats per minute or less instead of the usual 60-80 beats per minute, which greatly reduces the heart's efficiency.
Children born with only one ventricle undergo surgery called a Fontan procedure, which diverts blood returning from the veins directly to the main artery leading to the lungs, instead of the blood being pumped from the heart.
There are two ventricles in a normal heart - one pumps blood to the lungs and the other pumps blood to the rest of the body.
As part of the workup, a CMRI was obtained, including a dedicated and comprehensive wall motion analysis delayed-enhancement imaging (DE) of the left and right ventricles after 0.2 mmol/kg of the contrast agent management.
