Key result
Median sternotomy for left anterior descending artery grafting resulted in a 100% 5-year survival rate compared to 86.4% for anterior minithoracotomy, alongside significantly shorter operation times.
Why the study?
Does off-pump CABG via median sternotomy compared to left anterior minithoracotomy improve long-term survival and reduce operative time in patients undergoing single-vessel LAD bypass?
Observational (n=30)
No
Does off-pump CABG via median sternotomy compared to left anterior minithoracotomy improve long-term survival and reduce operative time in patients undergoing single-vessel LAD bypass?
Absolute Event Rate: 100% vs 86.4%
Off-pump CABG via median sternotomy for single-vessel LAD disease may offer shorter operative times and excellent long-term survival compared to a minithoracotomy approach.
Sternotomy may confer survival and time advantages in single-vessel LAD grafting; leaves open need for randomized confirmation before practice change.

Iwahashi et al. (2007) conducted an observational in One-vessel disease (left anterior descending artery) (n=30). Median sternotomy (OPCAB) vs. Anterior minithoracotomy (MIDCAB) was evaluated on 5-year actuarial survival rate. Median sternotomy for left anterior descending artery grafting resulted in a 100% 5-year survival rate compared to 86.4% for anterior minithoracotomy, alongside significantly shorter operation times.
