Cirugía de revascularización miocárdica de la arteria descendente anterior con arteria mamaria interna izquierda sin circulación extracorpórea: Experiencia en el largo plazo

Resumen

Background: In recent years the use of left internal mammary
artery (LIMA) as a graft 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 graft 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)
