Key result
A 78-year-old woman with takotsubo syndrome developed transient biventricular dysfunction with pressure gradients of 60 mmHg in the left ventricle and 28 mmHg in the right ventricle, which resolved within 16 days.

No
This case report demonstrates transient biventricular dysfunction with pressure gradients in Takotsubo-like cardiomyopathy, which resolved but could be provoked by dobutamine stress.

Transient biventricular gradients may occur and resolve in takotsubo; single case leaves open clinical relevance and need for prospective study.
A 78-year-old woman was admitted to our hospital due to chest oppressive sensation. Admission electrocardiography revealed ST-segment elevation in I, II, III, aV(F) and V(2-6) leads. Left ventriculography showed apical akinesis and basal hyperkinesis with a pressure gradient of 60 mmHg between the left ventricular apex and the base. Right ventriculography also showed similar abnormal wall motion with a pressure gradient of 28 mmHg. Follow-up cardiac catheterization after 16 days showed normal wall motion with no pressure gradients. However, dobutamine stress (10 microg/kg/min) caused a pressure gradient of 60 mmHg between the left ventricular apex and the aorta.

Kurisu et al. (2005) conducted a case report in Takotsubo syndrome (n=1). Takotsubo syndrome was evaluated. A 78-year-old woman with takotsubo syndrome developed transient biventricular dysfunction with pressure gradients of 60 mmHg in the left ventricle and 28 mmHg in the right ventricle, which resolved within 16 days.
