A case of ultrashort-acting beta-blocker landiolol hydrochloride for takotsubo syndrome with left ventricular outflow tract obstruction.

Takotsubo syndrome (TTS) has been known to have a favorable prognosis. Beta-blockers are reported to be effective for TTS patients with cardiogenic heart failure due to left ventricular outflow tract (LVOT) obstruction. However, there is no report on ultrashort-acting beta-blockers being used for treating TTS, and there are no clear guidelines for their dosages or applications.
