An aneurysm of the left ventricle (LV)can develop after a severe myocardial infarction.The affected area of the myocardium is replaced by thin scar tissue that can rupture.The LV undergoes remodeling when the scar stretches as a result of the left ventricular pressure and forms an aneurysm.Left ventricular aneurysmectomy (LVA)is the excision of an aneurysmal portion of the left ventricle.LVA is a form of left ventricular reconstruction undertaken to optimize cardiac function.Select the appropriate nursing actions in preparation for LVA surgery.

The patient is placed in the supine position.The setup is the same as that described for open-heart surgery,with the addition of synthetic patch material,Teflon felt pledgets,and 0,3-0,and 4-0 cardiovascular sutures.Occasionally,Teflon felt strips are required to bolster the suture lines.Patch closure of the ventriculotomy (endoaneurysmorrhaphy)is performed more often than the traditional excision,plication,and oversewing of the ventricular tissue.Patch closure better preserves the geometry of the left ventricle.A circular cuff of scar tissue is left,through which a purse-string suture with felt pledgets is placed through the rim of the scar.A patch of woven Dacron is sewn to the rim with interrupted sutures.A second (internal)patch of pericardium may be placed for hemostasis.
