Hypertrophic Obstructive Cardiomyopathy and Takotsubo Syndrome: Could They Coexist?

Introduction: Takotsubo syndrome (TKS) is generally caused by a stressful condition, and it usually has a good prognosis after the recovery of left ventricular function. About 70% of the cases of hypertrophic cardiomyopathy may develop obstruction in the left ventricular outflow tract (LVOT), which is responsible for heart failure. Case Presentation: We present a unique case where TKS occurred in a middle-aged male patient with hypertrophic obstructive cardiomyopathy (HOCM) without a clearly identifiable initial stress trigger. Conclusions: In the setting of acute left ventricular function depression in HOCM, a comprehensive differential diagnosis should be established. Treatment should be based on hemodynamic changes. After recovery, the prognosis is related to HOCM.
