Dynamic left ventricular outflow tract obstruction in apical ballooning syndrome (Takotsubo cardiomyopathy)

Perfusion. 2015 Jan;30(1):82-4. doi: 10.1177/0267659114536584. Epub 2014 May 21.

Abstract

Patients with apical ballooning syndrome may develop dynamic left ventricular outflow obstruction due to systolic anterior motion of the mitral valve leaflet and secondary functional mitral regurgitation, causing decreased cardiac output and hypotension. If suspected, bedside echocardiography will quickly confirm this complication. Positive inotropic/chronotropic agents should be avoided as they may exacerbate outflow tract obstruction, resulting in further hemodynamic compromise.

Keywords: Takotsubo; apical ballooning syndrome; dynamic outflow tract obstruction; hypotension; mitral regurgitation; systolic anterior motion.
