title: Knowledge management in cardiac surgery: the second tehran heart center adult cardiac surgery database report.
abstract: BACKGROUND
  The Adult Cardiac Surgery Databank (ACSD) of Tehran Heart Center was established in 2002 with a view to providing clinical prediction rules for outcomes of cardiac procedures, developing risk score systems, and devising clinical guidelines. This is a general analysis of the collected data.
  
  
  METHODS
  All the patients referred to Tehran Heart Center for any kind of heart surgery between 2002 and 2008 were included, and their demographic, medical, clinical, operative, and postoperative data were gathered. This report presents general information as well as in-hospital mortality rates regarding all the cardiac procedures performed in the above time period.
  
  
  RESULTS
  There were 24959 procedures performed: 19663 (78.8%) isolated coronary artery bypass grafting surgeries (CABGs); 1492 (6.0%) isolated valve surgeries; 1437 (5.8%) CABGs concomitant with other procedures; 832 (3.3%) CABGs combined with valve surgeries; 722 (2.9%) valve surgeries concomitant with other procedures; 545 (2.2%) surgeries other than CABG or valve surgery; and 267 (1.1%) CABGs concomitant with valve and other types of surgery. The overall mortality was 205 (1.04%), with the lowest mortality rate (0.47%) in the isolated CABGs and the highest (4.49%) in the CABGs concomitant with valve surgeries and other types of surgery. Meanwhile, the overall mortality rate was higher in the female patients than in the males (1.90% vs. 0.74%, respectively).
  
  
  CONCLUSIONS
  Isolated CABG was the most prevalent procedure at our center with the lowest mortality rate. However, the overall mortality was more prevalent in our female patients. This database can serve as a platform for the participation of the other countries in the region in the creation of a regional ACSD.
