title: [Doppler echocardiography in the diagnosis of mechanic complications of acute myocardial infarction].
abstract: OBJECTIVE
  To evaluate the ability of bedside emergency Doppler/Echocardiographic (ECOCG/DP) studies in the diagnosis of mechanic complications during acute myocardial infarction (AMI).
  
  
  METHODS
  Retrospective analysis of 44 fatal AMI cases, studied by ECOCG/DP and with diagnostic confirmation by surgery and/or necropsy.
  
  
  METHODS
  Patients (pts) with AMI admitted to an Intensive Care Unit of a tertiary Hospital (UCIM), Hospital de Santa Maria.
  
  
  METHODS
  44 fatal AMI cases were analysed (24 men and 20 women; mean age +/- SD: 72 +/- 9 years) and were divided in two groups according to Killip classification in Group 1 (III/IV): 35 pts and Group 2 (I/II): 9 pts.
  
  
  METHODS
  ECOCG/DP was performed in a routine basis at admission, using all standard views and by subcostal view when in an emergency scenario.
  
  
  RESULTS
  In 20 pts with bad left ventricular function (LVF) (Group 1) at admission, ECOCG/DP monitoring showed that death was due to worsening of LVF, which was confirmed by necropsy. In the other 15 pts of this group, ECOCG/DP documented the clinical diagnosis of cardiac rupture (free wall: 4 pts; papillary muscle: 4 pts; interventricular septum: 7 pts) which was confirmed by surgery and/or necropsy. In the 9 pts of Group 2, ECOCG/DP disclosed, at admission, good LVF in all. In 5 pts there was a sudden worsening clinical status, and ECOCG/DP showed a severe pericardial effusion with right chambers collapse, highly suggestive of free wall rupture also confirmed at necropsy. In the other 4 pts, ECOCG/DP showed aggravation of wall motion abnormalities and of LVF without rupture, once again in agreement with necropsy. Five clinical cases are presented for illustration of this issue.
  
  
  CONCLUSIONS
  In the 44 fatal AMI cases of our study there was complete agreement between the ECOCG/DP and necropsy studies. In AMI patients, ECOCG/DP monitoring can in a routine basis, evaluate wall motion abnormalities and LVF. In an emergency setting ECOCG/DP can diagnose all the mechanic complications with a great certainty.
