ANGIOCARDIOGRAPHY IN INFANTS AND CHILDREN New Technic

An apparatus is described which permits taking four roentgenograms/sec. Its use in angiocardiography is demonstrated by a series of cases with congenital cardiac anomalies. This method of investigation has proved most useful in studying the cyanotic group and in demonstrating shunts from right to left. A variety of different technics may, however, yield useful information in the noncyanotic group also. The procedures outlined are most valuable in the newborn period where congenital cardiac anomalies are so commonly encountered and where their differentiation is particularly difficult. The information collected in this manner has been, in many instances, a help to the surgeons in planning suitable surgery.
