Aortic valve replacement can be complicated by severe dynamic left ventricular outflow obstruction from mitral systolic anterior motion, causing severe postoperative hemodynamic instability.
Mitral systolic anterior motion causing severe dynamic left ventricular outflow obstruction is an under-recognized complication that should be considered in patients with severe hemodynamic instability after aortic valve replacement.

This case illustrates a severe dynamic left ventricular outflow obstruction after aortic valve replacement (AVR). This phenomenon is little recognised but probably occurs more frequently than appreciated, and should be considered when managing patients with severe haemodynamic instability after AVR. The possible mechanisms and treatment are discussed.
