The funnel consisted of myocardium that formed a continuity between the right wall of the atrioventricular canal and the ventricular septum.
The myocardium of the rudimentary right ventricle is separated by the atrioventricular groove from the muscular floor of the blind-ending right atrium.
As discussed above, the immature contractile apparatus of the fetal myocardium does not tolerate increased afterload.
In the heart, tissue cysts were in the pericardium, myocardium, endocardium and in the mitral valves.
Many large tortuous vessels with continuous flow patterns, which were thought to be collaterals were seen throughout the myocardium.
The wall of this chamber had viable myocardium and communicated with the main body of the left ventricle through a large fibrous orifice.
The glucose-based cardioplegic solutions have been used clinically with protective effects on adult myocardium at concentrations ranging from 2.5 to 5.0% glucose.
Macroscopically visible myocardium may be confined to the base of the heart in the region of the tricuspid orifice.
