Viragint

A male given to viraginity. Virchow's Method (of opening the heart). The heart is opened in situ. The first incision is made in the right ventricle (many open the right auricle first) along the ventricular ridge, from near the auriculo-ventricular groove to near the apex. The second incision opens the right auricle midway between the entrances of the venae cavje. In the left auricle the incision is carried from the left superior pulmonary vein to near the auriculo-ventricular ring. The incision through the left ventricle begins just behind the base and ends just short of the apex. It must be carried deeply through the wall of the heart. The he.irt is now removed. To do this the organ is grasped with the index finger of the left hand in the left ventricle and the thumb in the right; the heart is then raised by the apex and the venae cavse, the pulmonary veins, and the pulmonary artery, and the aorta divided, taking care that the incisions are not too close to the heart. The next step is to open the ventricles. For this purpose the heart is placed exactly in the position it occupied in the body. One blade of the sci ors is then introduced near the lower end of the incision in the right ventricle and carried outward in the direction of the pulmonary artery. The incision for the left ventricle commences at the apex of the heart and divides the anterior wall of the ventricle close to the septum, and is continued out through the aorta. These are the principal incisions; it is customary, however, to make at least two others, viz., one connecting the incision in the right auricle with that in the right ventricle, and one connecting that in the left auricle with the incision in the left ventricle.
