myocardium

the muscular tissue of the heart

Myocardium

 

the muscular layer that constitutes most of the heart. It consists of striated muscle tissue made up of a dense aggregation of muscle cells. A functional characteristic of the myocardium is rhythmic, automatic contraction alternating with relaxation, which continues without interruption throughout the life of the organism.

The histological pattern observed ranges from normal myocardium to acquired fibrotic changes superimposed on the background of normal myocardium.
In the mid- and basilar-inferior septum, inferior wall, and posterior-lateral wall RCA territory (Figure 6), thin linear < 50% subendocardial DHE is demonstrated, consistent with subendocardial myocardial scar, but with viable myocardium.
The engineered myocardium could then be used to engraft the mice that had contributed the eggs for parthenogenesis.
Several cardiac abnormalities may be associated with noncompaction of the myocardium, including congenital right or left ventricular outflow tract abnormalities, such as pulmonary atresia with intact ventricular septum (14).
Also called myocardium, this type is found only in the heart.
In the present study, we reported for the first time that intravenous administration of polydatin before I/R significantly limited the infarct size, creatine phosphokinase (CPK) and lactate dehydrogenase (LDH) leakage from the damaged myocardium after I/R.
This study suggests that low-level cumulative exposure to lead could be associated with diminished future cardiac conductivity in the ventricular myocardium.
In an effort to answer this question a porcine model was developed in which a segment of myocardium and its coronary supply could be isolated from the remainder of the cardiac tissue.
Various image sequences can be used, either rendering 'dark blood imaging' where the blood pool is darker than the myocardium, or 'bright blood imaging' where the myocardium is darker than the blood pool.
Antioxidant therapy after I/R may help the myocardium recover from reactive oxygen species (ROS) induced damage.
Cardiac visualisation involves maximising the difference between myocardium and blood pools.
