Alerts to potential IABP harm in LVOT obstruction shock; single case leaves open need for validation before practice change.
Does an intra-aortic balloon pump exacerbate left ventricular outflow tract obstruction in a patient with takotsubo and hypertrophic cardiomyopathy?
An IABP should not be used in shock with LVOT obstruction as it can exacerbate the outflow tract gradients.
Griffin et al. (2023) studied this question. Intra-aortic balloon pump therapy exacerbated left ventricular outflow tract obstruction in a patient with shock due to hypertrophic cardiomyopathy and takotsubo syndrome.
