title: [Current complications of heart catheterization. Analysis of 100 cases].
abstract: OBJECTIVE
  To analyse the impact of the new cardiac catheterization techniques on the complication profile of these procedures.
  
  
  METHODS
  One thousand consecutive patients who underwent cardiac catheterization from August through December, 1989 (739 diagnostic and 201 therapeutic procedures), who were followed up until hospital discharge. Complications were classified accordingly to their type and severity, and were related to the procedure employed and to the left ventricular ejection fraction.
  
  
  RESULTS
  There were no complications in 77.7% of the population studied. In the remaining 236 patients the incidence of mild, moderate and severe complications were, respectively: 11.2%, 7.3% and 3.8%. Severe vascular complications occurred in 0.5%, cardiac perforation requiring emergency surgical repair in 0.1%, severe arrhythmias in 1.4%, acute myocardial infarction in 0.4%, acute pulmonary edema in 0.3% and fatal events in 0.5% patients.
  
  
  CONCLUSIONS
  Despite the increasing application of interventional techniques and the greater number of acutely ill patients referred to cardiac catheterization, these procedures have proved to be safe with a low complication rate.
