Abstract
Right-to-left circulatory shunts were produced in 11 mongrel dogs by anastomosis of the left atrial appendage to the pulmonary artery. When injections of Kr85 in solution were made proximal to the shunt the level of radioactivity in arterial blood drawn during the first 20 sec. after injection was always greater than 1400 cts./min. In dogs without shunts, however, similar injections resulted in arterial blood counts of 206/min. or less. The technic thus provides a new method for detection and localization of venoarterial shunts.Keywords
