Several types of pedicles containing the mammary artery were sutured to the surface of the hearts of dogs in an effort to add blood the coronary arterial system from an extracardiac source. Through this approach, the basic physiologic principles governing the formation of collateral arterial channels in the body are believed to be observed more closely than was done in other procedures for the same purpose. A pedicle containing the mammary artery, strip of the sternocostalis muscle, connective tissue, and the mammary vein was found to the most promising of the types tested. This pedicle was found to be capable of forming extensive collateral branches to surrounding adhesions. Thrombosis of the mammary artery was avoided. Very few collateral channels went to the coronary arterial system. This was probably because an adequate chronic coronary arterial hypotension was not successfully produced the animals.
