Cirugía de revascularización miocárdica de la arteria descendente anterior con arteria mamaria interna izquierda sin circulación extracorpórea: Experiencia en el largo plazo / Beating heart anterior descending coronary artery grafting with left internal mammary artery: A long term follow up experience

ABSTRACT

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).
