    Abstract:
    Dobutamine stress echocardiography is widely used for the evaluation of coronary artery disease. This form of stress echocardiography is safe but not without complications. We report a case of hypotension and syncope during dobutamine stress echocardiography in which a severe intraventricular gradient of over 200 mmHg and systolic anterior movement of the mitral valve were observed.
