"Incompatible Housemates": Hypertrophic Obstructive Cardiomyopathy and Takotsubo Syndrome.


ABSTRACT: This case report concerns an 81-year-old woman with previously well-controlled hypertrophic obstructive cardiomyopathy (HOCM). She was referred to our hospital because of the acute onset of takotsubo syndrome. Echocardiography revealed basal hyperkinesis due to takotsubo syndrome superimposed on septal hypertrophy, which resulted in the reappearance of prominent left ventricular outflow tract obstruction (LVOTO). Although she developed cardiogenic shock triggered by atrial fibrillation, LVOTO was successfully mitigated by aggressive fluid resuscitation, rhythm control, and the administration of ?-blocker. We herein report a rare case with catastrophic hemodynamics due to the incidental combination of HOCM and takotsubo syndrome.
