ABSTRACT
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. AIM: To report 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 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).
