Systolic Anterior Movement

In the perioperative setting, norepinephrine is used to increase blood pressure, an effect mediated mostly via arterial and venous vasoconstriction. Thus, norepinephrine is, allegedly, less likely to cause or worsen left ventricular outflow tract obstruction (LVOTO) than other inotropes. We report a case of norepinephrine-associated dynamic LVOTO and systolic anterior movement in a predisposed patient. This report highlights that unrecognised dynamic LVOTO may worsen shock parameters in patients treated with norepinephrine who have underlying myocardial hypertrophy.
