Right Ventricle Anatomy
The other important internal features of the right ventricle are the papillary muscles of which there are three. It is located in the lower right portion of the heart below the right atrium and opposite the left ventricle.

The right ventricle extends from the right atrium to the apex of the heart.
Right ventricle anatomy. The right ventricle projects to the left of the right atrium and when viewed in the cardiac short axis plane is semilunar in shape wrapping around the anterolateral aspect of the left ventricle lvit has thinner walls than the left ventricle due to lower right sided pressures compared to the left ventricle. Forms the major portion of the anterior surface of the heart. As deoxygenated blood flows into the right atrium it passes through the tricuspid valve and into the right ventricle which pumps the blood up through.
Septal has attachments to the interventricular septum and. The right ventricle is one of the hearts four chambers. Not long ago the right ventricle rv was considered an unnecessary part of the normal circulation.
Right ventricle gross anatomy. The right ventricle pumps blood into the pulmonary circulation to the lungs and the left ventricle pumps blood into the systemic circulation through the aorta. Its attached at one end to the ventricular septum and at the other end to the base of the anterior papillary muscle.
The right ventricle in the normal heart is the most anteriorly situated cardiac chamber since it is located immediately behind the sternum. This is called the septomarginal trabecula. It carries the right bundle of the atrioventricular bundle to the anterior wall of the right ventricle.
It also marks the inferior border of the cardiac silhouette. Anterior is the largest of the three muscles. The right ventricle projects to the left of the right atrium and when viewed in.
Posterior originates from the inferior wall of the right ventricle. On contrast enhanced chest ct and cardiac mri. While factually correctablation or replacement of the rv free wall can be well tolerated by experimental animals without reduction in cardiac output and many surgical algorithms for congenital heart diseases culminate in a circulation devoid of a sub pulmonary ventricle a fontan.
Ventricle heart in a four chambered heart such as that in humans there are two ventricles that operate in a double circulatory system.
