Abstract

Background

Takotsubo cardiomyopathy can occur at the early phase of severe acute brain injuries. In the case of cardiac output decrease or shock, the optimal treatment is still a matter of debate. Due to massive stress hormone release, the infusion of catecholamines may have limited effects and may even aggravate cardiac failure. Other inotropic agents may be an option. Levosimendan has been shown to have potential beneficial effects in this setting, although milrinone has not been studied.

Methods

We report a case of a young female presenting with inverted Takotsubo cardiomyopathy syndrome after severe traumatic brain injury.

Results

Due to hemodynamic instability and increasing levels of infused norepinephrine, dobutamine infusion was begun but rapidly stopped due to tachyarrhythmia. Milrinone infusion stabilized the patient's hemodynamic status and improved cardiac output without deleterious effects.

Conclusion

Milrinone could be a good alternative when inotropes are required in Takotsubo cardiomyopathy and when dobutamine infusion is associated with tachyarrhythmia.
