Syncope Caused by Severe Hypotension and Intraventricular Gradient During Dobutamine Stress Echocardiography

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.
