AB KEY  POINTSCatecholamine  toxicity  seems  to  be  the  key  mechanism  of  takotsubo.Emotional  or  physical  triggers  are  almost  always  present  in  the  history  of  takotsubo.The  dominant  pattern  is  the  apical  ballooning  form.Takotsubo  is  a  diagnosis  of  exclusion:  myocardial  infarction  and  myocarditis  should  be  ruled  out,  generally  requiring  coronary  angiography.  MRI  may  also  be  useful.Echocardiography  is  the  main  tool  to  diagnose,  follow,  and  detect  complications.Severe  cardiac  failure  and  cardiogenic  shock  are  the  main  causes  of  ICU  hospitalization.Left  ventricular  outflow  tract  obstruction  is  frequent  in  patients  with  takotsubo.Management  is  based  in  very  little  evidence:  anticoagulants,  beta-blockers  (in  case  of  obstruction),  levosimendan,  and  mechanical  hemodynamical  support  have  been  advocated.
