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

Abstract

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. Herein, we describe a 72-year-old woman in whom landiolol hydrochloride was used in the acute phase of TTS with LVOT obstruction. In this case, the dose of landiolol hydrochloride was increased to 10 μg/kg/min, resulting in improvement of LVOT obstruction, which led to hemodynamic stabilization.
