Takotsubo cardiomyopathy in a patient with previously undiagnosed hypertrophic cardiomyopathy with obstruction.

Takotsubo cardiomyopathy (TCM) is usually characterized by left ventricular anteroapical dysfunction in the absence of significant coronary disease commonly precipitated by an emotional or stressful trigger. Hypertrophic cardiomyopathy (HCM) is usually diagnosed on the basis of symptoms, family history, echocardiography, or by the presence of a characteristic murmur. We report a unique case of TCM occurring in a patient with previously undiagnosed HCM with left ventricular outflow tract (LVOT) obstruction who presented with an acute coronary syndrome and ultimately underwent successful alcohol septal ablation. The potential pathophysiologic correlations are discussed.
