The<unk>  was created by Alfred<unk>  and C. Rollins<unk> . It was described in 1950. Alfred<unk>  was an American Surgeon most known for his work on the Blue Baby syndrome. C. Rollins<unk>  was also an American Surgeon but was best known for his work in cardiology. The procedure that these two men created, known as the<unk> , was a new concept within atrial spectroscopy. This procedure had been experimented on the right atrium of dogs before Dr.<unk>  and Dr.<unk>  had performed it on humans. It involves the intentional creation of a septal defect in order to alter the flow of oxygenated blood. It was devised as a palliative correction for transposition of the great vessels. The<unk>  was a cardiothoracic procedure created in the 1950s. The<unk>  was created to enhance intracardiac combinations. A majority of the surgeries using this procedure were performed in pediatrics on infants ranging from one day to five months of age. Of all the children who had this surgery, only one had to undergo a second operation to repair damage not fixed during the<unk> . According to Behrendt, Orringer, and Stern, there were only ten early deaths out of the forty-eight children the operation was performed on. The deaths were of children that were less than one month old due to extensive measures taken during the operation. The procedure also had a relatively high mortality rate of only twenty-one percent while it was performed however, because of the excessive mortality rate it is no longer used in today's medical society. This procedure was a combination of two circulations (Pulmonary and Systematic). Due to the intracardiac mixing, the procedure can cause postoperative arrhythmias, cerebral thrombosis, adhesions develops in the pericardial space, and many infants will face death between the septectomy. It was developed by Vivien Thomas at the Hunterian Laboratory ("the dog house") of Johns Hopkins and described by Alfred<unk>  and C. Rollins<unk> . __TOC__
