The ventricle aneurysms are severe complications of the miocardium infarctions decreasing the ventricle function and increasing the morbi-mortality rate. The surgical correction proposed by Cooley, in 1958, has changed the evolution of this complication. In 1985, Jatene gave a worldwide contribution to the Geometrical Reconstruction of the left ventricle, showing superior functional results and low mortality rate. We present a technique modification of the aneurysmectomy with geometrical reconstruction utilizing semi-rigid prosthesis double-coated with bovine pericardium with an implantation stent made of Dacron out of which the flap is projected, also made of bovine pericardium. They are available with their 19 up to 27 mm wide diameter with the corresponding sizer and they have a radiopaque stent for radiological identification. Once the aneurysm has been opened, the transition are between contractile tissue and the fibrous zone is delimited. Polyester 2-0 stitches are passed separately in inverted U shape supported by "pledgets" of Teflon all around the venticle circle and with the diameter sizer we evaluate the aneurysm original transaction which enlarged with the time, setting the right size of the prosthesis. The Dacron stent is then shown reducing the aneurysm transition to the size of the ring so that it gives the ventricle its original shape with no loss of noble tissue, remodellign its cavity. Then with a continuous suture from the bovine pericardium flap, projected from the stent and the fibrous tissue, the hemostasia is completed. From 16 patients submitted to the technique, 11 patients studied by the 100-shortening-chordae computerized system. The average ejection fraction (Dodge/Kennedy N = 0.55 - 0.81) of the pre-operative was 0.37 and 0.53 for the post-operative showing a 43% improvement in the miocardium function.
