Abstract

Dynamic Left Ventricular Outflow Tract Obstruction: Comparison between Dobutamine and Exercise Stress-Echo

A 62 years old man with high cardiovascular risk profile underwent dobutamine stress echocardiography for suspected silent myocardial ischemia; the test showed severe dynamic intraventricular obstruction (maximum gradient 210 mmHg) and was prematurely stopper for high intraventricular gradient. A maximal exercise stress-echo, performed according to Bruce protocol, showed the same response, in absence of any new asynergic area.
