Right Ventricular Anatomy

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. The right ventricle in the normal heart is the most anteriorly situated cardiac chamber since it is located immediately behind the sternum.

The normal rv is anatomically and functionally different from the left ventricle which precludes direct extrapolation of our knowledge of left sided physiopathology to the right heart.

Right ventricular anatomy. The right ventricle is one of the hearts four chambers. It also marks the inferior border of the cardiac silhouette. 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 lv.

The point of the chordae tendineae and the papillary muscles is to prevent these cusps to prevent the tricuspid valve from being averted back into the right atrium when the ventricle contracts and the pressure increases and the back flow of blood forces against the tricuspid valve. There is increasing recognition of the crucial role of the right ventricle rv in determining functional status and prognosis in multiple conditions. The mesh surface is the left ventricle.

Septal has attachments to the interventricular septum and. It has thinner walls than the left ventricle due to lower right sided pressures compared to the left ventricle. The moderator band is located in the right ventricular apex that connects the interventricular septum to the anterior papillary muscle.

Posterior originates from the inferior wall of the right ventricle. It is located in the lower right portion of the heart below the right atrium and opposite the left ventricle. Anterior is the largest of the three muscles.

Rv remodelling in diseased hearts can result in profound shape change as in this patient b with dilated rv due to severe pulmonary regurgitation following repair of tetralogy of fallot. When looking within the heart it appears as any other trabecula would except that the moderator band does not. The other important internal features of the right ventricle are the papillary muscles of which there are three.

The right ventricle extends from the right atrium to the apex of the heart. Forms the major portion of the anterior surface of the heart.
