title: Long-Term Survival After Minimal Invasive Direct Coronary Artery Bypass (MIDCAB) Surgery in Patients With Low Ejection Fraction.
abstract: OBJECTIVE
  : The long-term survival after minimal invasive direct coronary artery bypass (MIDCAB) surgery to any coronary territory in patients with ejection fraction of ≤30% was investigated for the first time in literature.
  
  
  METHODS
  : Seventy-three patients with primary MIDCAB and 89 patients with reoperative MIDCAB were studied including preoperative risk factors, operative details, early postoperative complications, and survival up to 10 years postoperatively.
  
  
  RESULTS
  : Despite the high-risk profile of the patients, the MIDCAB approach for targeted revascularization resulted in excellent short-term results. Ventricular arrhythmia contributed to four of six early deaths. Survival at 5 years postoperatively was 62.5% for primary MIDCAB and 43.2% for reoperative MIDCAB and at 10 years was 36.9% and 29.5%, respectively. Functionally complete vascularization correlates with significantly better long-term survival particularly in primary MIDCAB procedures.
  
  
  CONCLUSIONS
  : MIDCAB is a valuable option for targeted revascularization in high-risk patients with low ejection fraction and reoperation.
