From June, 1977, to December, 1978, 14 children had intraaortic balloon support after open-heart operation. There were 6 long-term survivors. Four of 5 children more than 10 years old and 2 of 5 children between 5 and 10 years old survived. All 4 children less than 5 years old died. In the youngest group, it was difficult to use the balloon successfully because of their very low cardiac output coming off bypass and their greater aortic elasticity. The smallest sizes of balloon available were found to be too long, extending well below the diaphragm in younger patients. In 7 out of 10 patients 5 years old or more, augmentation was obtained.
