Basic Anatomy of the Normal and Diseased Heart
Conventional chest roentgenography, angiocardiography, and cast corrosion preparation studies of the heart have been supplemented by anatomical sections of cadavers in the horizontal, sagittal, and coronal planes. The heart is the most important anatomical structure of the middle mediastinum. The ventral coronal section of the heart (Figure 1) exhibits, from left to right, the superior vena cava (above), the right atrium (below) the ascending aorta (in the middle), the pulmonary trunk (to the right), and the right ventricle (below the aorta and pulmonary trunk). The dorsal coronal section of the heart (Figure 2) shows the bifurcation of the trachea (above) with the right and left primary divisions of the pulmonary trunk (in front of the main bronchi) and the pulmonary veins and left atrium (below). Above the right main bronchus one sees the arch of the azygos vein and above the left main bronchus, the arch of the aorta.
