Abstract:
Left ventricular outflow tract obstruction is now recognized as a common complication of takotsubo syndrome, resulting in more serious acute and long-term outcomes. We describe a case of takotsubo syndrome where a transient sigmoid septum produced left ventricular outflow obstruction and explore the mechanisms leading to this occurring. This phenomenon has not been previously described. <Learning objective: Left ventricular outflow tract (LVOT) obstruction is a complication of takotsubo syndrome. A sigmoid septum is a risk factor for LVOT obstruction occurring. This case highlights that a sigmoid septum can be transient and may be secondary to surge in catecholamines and inflammatory markers.>.
