Revascularización miocárdica de la arteria descendente anterior con arteria mamaria interna izquierda con circulación extracorpórea: seguimiento a 10 años

Thirty-four patients presented with unstable angina. On angiography, the LAD had aproximal obstruction in 35 patients. Sixteen presented with a myocardial infarction of the LADterritory. Six were managed previously with angioplasty; four had a new critical obstruction, 1 wascatalogued as a procedure failure, and one was totally occluded. There was no operative mortality,myocardial infarction, stroke or need for re operation. There were two late deaths, caused by anadvanced cardiac failure at 120 months in one patient, and chronic renal failure at 61 months offollow-up in another. Actuarial survival probability was 100%, 93% and 75% at 1, 5 and 10 years.Probability of freedom from angina was 98%, and freedom of suffering a new myocardial infarctionwas 100% at more than 10 years. The probability of no need for a new coronary procedure(angioplasty or surgery) also was 100% at more than 10 years.
