ABSTRACT
Hypertrophic cardiomyopathy (HCM) with hypertrophy of the basal septum is the most common etiology of left ventricular outflow tract (LVOT) obstruction. In this article, we report the case of a patient with a structurally normal heart who developed hemodynamic deterioration due to severe LVOT obstruction following treatment with catecholamines. Hypovolemia accompanied with a hyperdynamic condition, resulting from catecholamine treatment, may cause dynamic LVOT obstruction due to the systolic anterior motion of the mitral valve leaflet. The solution for this is early recognition and correction of aggravating factors such as, withdrawal of catecholamine therapy and volume replacement.
