TI  - Minimally invasive aortic valve replacement via hemi-sternotomy: a preliminary 
      report.
PG  - S134-7
AB  - OBJECTIVE: Aortic valve replacement has been approached by standard sternotomy. 
      We described a technique of aortic valve replacement where the aortic valve is 
      exposed through a hemi-sternotomy. Good exposure is obtained for aortic valve 
      surgery with standard aortic and right atrial cannulation to establish 
      cardiopulmonary bypass (CPB). METHODS: From October 1996 to April 1997, 19 
      consecutive aortic valve replacements (AVR) via hemi-sternotomy were performed by 
      one surgeon. The results were collected and analysed prospectively. Results are 
      expressed as mean +/- standard deviation. Nineteen patients (13 male, 6 female) 
      had AVR with this approach. Two cases were redo AVR. The mean age was 58+/-15 
      years. The New York Heart Association (NYHA) class was 2.8+/-0.7. RESULTS: Aortic 
      cross clamp time was 54+/-13 min. One of six patients requiring defibrillation 
      after reperfusion needed conversion to full sternotomy. Four patients were 
      extubated at the conclusion of surgery. One patient died 4 h postoperatively from 
      low cardiac output. All patients had normal valvular function demonstrated on 
      postoperative transoesophageal echocardiography. There were no neurological 
      events. CONCLUSIONS: Minimally invasive aortic valve replacement can be safely 
      performed via hemi-sternotomy with standard equipment. Less surgical trauma to 
      the sternum has the potential benefit of less pain and shorter intensive care and 
      hospital stay.
