Background. Intraaortic balloon pumping (IABP) is useful for support in patients with moderate left ventricular dysfunction. IABP is usually timed with the R wave of the electrocardiogram. We have utilized M-mode echocardiography timed IABP in children with left-side heart failure since 1994. Electrocardiogram timing seems inappropriate for children, who have much higher heart rates. We describe our experience with children who underwent IABP therapy before and after 1994, when echocardiographic timing was instituted.

Methods. We reviewed records of 29 children who underwent IABP for all indications at Primary Children’s Medical Center since 1988.

Results. Overall survival was 62.1% (18 of 29) in this series. Survival was similar for infants (odds ratio = 2.0, 95% confidence interval = 0.29 to 14.31, p = 0.43) and older children. Survival was similar in the echocardiography era when compared with the electrocardiogram era (odds ratio = 2.4, 95% confidence interval = 0.56 to 10.4, p = 0.44).

Conclusions. IABP is a useful means of support in children with left ventricular dysfunction. M-mode echocardiography is effective in triggering IABP. The sample size in this study is too small to detect a mortality rate difference.
