Morphological analysis of the myocardial fiber architecture of ventriculus cordis in normal and malformed human hearts.
In this study, ten normal and one malformed adult human hearts obtained from the collections of Gazi University Department of Anatomy were investigated. Muscle maceration techniques of Romeis and Torrant-Guasp have been used. In the normal heart, the superficial layer of ventricular myocardium has been detected. Then, middle layer was demonstrated by lifting up the fibers of this layer. Endocardium of ventricles was dissected and inner layer was observed. Consequently, direction of muscle fibers was examined in ventricular myocardium. Sections of muscle samples from an hypertrophied heart were prepared by routine light microscopic procedures. In the normal heart, a thin middle layer was present in right ventricle. This layer was appeared to be hypertrophied in the malformed heart.
