BAHAMONDES S, Juan Carlos et al. Beating heart anterior descending coronary artery grafting with left internal mammary artery: A long term follow up experience. Rev. méd. Chile [online]. 2009, vol.137, n.1, pp.18-24. ISSN 0034-9887.  http://dx.doi.org/10.4067/S0034-98872009000100003.

Background: In recent years the use of left internal mammary artery (LIMA) as a gran to anterior descending artery (DA) with the offpump technique has been associated with similar good long term results as with the on pump technique. Aún: To repon the results of LIMA to DA bypass grafting without extracorporeal circulation (EC) for isolated DA lesions. Patients and methods: Descriptive study of 80 patients subjected to coronary surgery between 1999 and 2007. Results: Mean age ofpatients was 63 + 10 years and 60 were male. There was no operative mortality or stroke. One patient with a myocardial infarction required a reoperation. Actuarial survival was 98% at 97 months. Conclusions: In this group ofpatients the use ofLIMA as a coronary bypass gran to DA with the off pump technique is a safe surgical procedure, providing a prolonged cardiac event free survival (mortality, angina, myocardial infarction, and need for a new coronary procedure).
