What is moderator band composed of?
The moderator band is covered externally by the endocardium that is mainly consisting of the endothelial layer of simple squamous epithelium, subendothelial layer of loose connective tissue and the subendocardial layer that connects the endocardium with myocardium.
What heart chamber contains the moderator band?
Location: The moderator band is located in the right ventricular apex that connects the interventricular septum to the anterior papillary muscle.
What is a moderator band in left ventricle?
Location: Also called false tendons, false chordate and left ventricular moderator bands among other names, left ventricular bands are fibromuscular structures in the left ventricle crossing the cavity or simply joining nearby trabeculations or papillary muscles left ventricle.
Does the left ventricle have a moderator band?
Moderator bands, seen in the right ventricle, are rarely seen in the left ventricle. Rarely, chordae tendinae or other fibrous bands may attach to the left ventricular wall, usually the interventricular septum.
What is the moderator band for?
The moderator band, also called the septomarginal trabecula, is a consistent structure in the morphologic right ventricle and can be helpful as a landmark in situations where the ventricles may be ambiguous (i.e. in some forms of congenital heart disease).
What would happen if the moderator band was severed?
The moderator band is a muscular band of heart tissue found in the right ventricle of the heart. If the moderator band was damaged, the AV valves would prolapse into the atria.
Why is left ventricle the thickest chamber of the heart?
The left ventricle of your heart is larger and thicker than the right ventricle. This is because it has to pump the blood further around the body, and against higher pressure, compared with the right ventricle.
What is the most muscular chamber of the heart?
The left ventricle, the most muscular chamber of the heart, then contracts with enough pressure to send the blood through the aortic valve and into the aorta.
What is apex of heart?
The tip of the left ventricle, opposite the base of the heart. The apex of the heart moves considerably with each heartbeat, and the point of maximal impulse (PMI) can be felt on the chest wall above the apex.
What is a left ventricle?
Left ventricle (VEN-trih-kul): one of the four chambers of the heart. The left ventricle pumps blood full of oxygen out to the body.
Does the left ventricle have Trabeculae Carneae?
There is one anterior and one posterior papillary muscle in the left ventricle of canines (1). The posterior papillary muscle, supporting the mitral valve, and the trabeculae carneae are also visible.
Which chamber of the heart does blood leave to go to the lungs?
The right ventricle pumps the blood to the lungs where it becomes oxygenated. The oxygenated blood is brought back to the heart by the pulmonary veins which enter the left atrium. From the left atrium blood flows into the left ventricle.
What is a false tendon in the heart?
Background: The left ventricular false tendon (FT) is an anomalous fibrous or fibromuscular band stretching across the left ventricle. The false tendons extend from the septum to the left ventricular free wall or, more rarely, from the septum to a papillary muscle.
Is the moderator band is found on both the right and left side of the heart?
The tricuspid valve is the atrioventricular valve located on the right side of the heart. It separates the right atrium from the right ventricle. The moderator band is found on both the right and left side of the heart.
What is a cardiac band?
The moderator band is an important anatomic landmark that is used to characterize the morphologic RV in congenital heart diseases. It provides support to the anterolateral papillary muscle, guides blood from the RV inflow tract to the outflow tract, and prevents RV overdistention, especially in cases of RV infarction.
