Right ventricular (RV) volumetric and morphological analysis is complicated by the trabeculations and geometric configuration of the RV chamber. To improve RV analysis, custom computer-aided design programs were employed to obtain RV volumes and three-dimensional models from biplane ventriculograms. Biplane RV ventriculograms were analyzed from 14 anesthetized dogs and 22 RV casts. Computed volumes were highly correlated with reference RV volumes (r = 0.98, n = 36, P less than 0.01) with a range of 5-73 ml. Three-dimensional wire-frame and solid models constructed from the ventriculographic images provided excellent detail and a new perspective in chamber shape. This modeling technique was then used to examine RV volumes, geometric conformation, and regional shortening in 10 pigs during inotropic stimulation and preload reduction. Changes in RV volumes, ejection fraction, and regional motion were detected as well as alterations in chamber conformation. In summary 1) computer-aided design offers an accurate and simplified means to compute RV volumes using basic microcomputer equipment, and 2) three-dimensional reconstruction provided a unique view of RV geometry and a means to examine regional RV function.
What else can I help you with?
What are the functions of the right ventricle?
recieves blood from the right atrium and pumps it into the main pulmonary artery
Why does The right ventricle have a less muscular wall than the left ventricle because the right ventricle?
The right ventricle has a less muscular wall than the left ventricle because it pumps blood to the lungs, which are located nearby, requiring less force. In contrast, the left ventricle must generate much higher pressure to pump blood throughout the entire body, necessitating a thicker, more muscular wall. This structural difference reflects the distinct functions and pressure requirements of each ventricle.
Which ventricle of the heart ejects blood towards the lungs?
right ventricle
Interventricular septum separates the left ventricle from what side?
right ventricle
What are the 4 chambers of the heart?
Right Atrium , Left Atrium , Right Ventricle , Left Ventricle
What are four functions of the heart?
There are 4 chambers of the heart and here are what they do. The Right atria is where blood comes into this part from the vena cava and is pumped to the right ventricle The Right ventricle pumps blood to the lungs Left atria is where the blood returns to the heart through the left atria Left ventricle is where the blood is pumped from the aorta to the rest of the body
What wall separates the right ventricle from the left ventricle of the heart called?
The intraventricular septum separates the right ventricle from the left ventricle.
What are the four ventricles of the ventricular system?
the different types of ventricles are the left ventricle and the right ventricle.
How many chambers does the hearts contain?
The heart contains 4 chambers The Right Atrium The Left Atrium The Right Ventricle and the Left Ventricle
In sheep heart the right atrium is what from right ventricle?
It is superior to the right ventricle Inferior <
What are the four chambers of the heart are called?
The four chambers are; Left atrium Right atrium Left Ventricle Right Ventricle The two upper chambers are called atria (singular: atrium) and the two lower chambers are called ventricles. There are four chambers of the heart - the right atrium, left atrium, right ventricle and left ventricle.
What are the four chambers of the heart and their functions?
The heart is made up of 4 chambers. Each side has an atrium and a ventricle. The right atria collects de-oxygenated blood from two major veins in the body; this blood is then pumped into the right ventricle, where it is then ejected into the pulmonary arteries, where is goes to the lungs to collect oxygen. Upon returning to the heart, the blood enters the left atrium; it is then pumped into the left ventricle, where it is then ejected into the aorta and distributed throughout the body.
