[Beating heart anterior descending coronary artery grafting with left internal mammary artery: a long term follow up experience].
BACKGROUND
In recent years the use of left internal mammary artery (LIMA) as a gran to anterior descending artery (DA) with the off pump technique has been associated with similar good long term results as with the on pump technique.


OBJECTIVE
To report the results of LIMA to DA bypass grafting without extracorporeal circulation (EC) for isolated DA lesions.


METHODS
Descriptive study of 80 patients subjected to coronary surgery between 1999 and 2007.


RESULTS
Mean age of patients 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 of patients the use of LIMA 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).
