title: [Off pump coronary artery bypass grafting in 51 cases].
abstract: OBJECTIVE
  To study the cost-effective minimal invasive coronary bypass surgery which decreases the complication associated with cardiopulmonary bypass, alleviates postoperative pain, and promotes recovery.
  
  
  METHODS
  From August 1998 to November 1999, fifty-one patients underwent minimal invasive coronary bypass surgery with off pump technique. Age range was from 39 to 80 years (average 64). Thirty-five patients suffered from myocardial infarction and nine patients diabetes. Left ventricular ejection fraction was from 20%-72% (average 53%). All procedures were completed through medial sternotomy. Stabilizers of CTS, Octopus, and USSC were applied. The average graft was 2.7 per case.
  
  
  RESULTS
  The operative mortality was 1.9%. The average ICU and hospital stay were 1.2 and 6 days, respectively. The average chest drainage and blood transfusion were 415 ml and 160 ml, respectively. Fifty patients survived from surgery. All survived patients had no symptoms of angina during the short-term follow-up (1 to 8 months). Two patients were followed up by postoperative coronary angiography, which showed a satisfactory anastomosis rate of 100%.
  
  
  CONCLUSIONS
  Minimal invasive coronary bypass surgery is safe, cost-effective, and suitable for patients with high risk of extracorporeal circulation. It can also be used for multivessel disease.
