title: [Left ventriculoplasty for ischemic cardiomyopathy with a left ventricular aneurysm].
abstract: We report 3 cases of left ventriculoplasty (LVP). They were chosen according to classification of the preoperative left venticle (LV) shape; an apex type and anteroseptal type. We think that an apex type has an indication for a Dor operation and the treatment of an anteroseptal type should be chosen between the following 2 methods. One is an overlapping method. It has the advantage of having to use no intracardiac patch which would remain akinetic area. It is therefore suitable for relatively small LV aneurysms without involvement of the proximal diagonal branches. However, it has the disadvantage of having to cut some distal diagonal branches in order to perform the volume reduction. The other method is a septal anterior ventricular exclusion (SAVE) operation. It is suitable for larger LV aneurysms which involve the proximal diagonal branches due to its advantage of being able to perform the LVP without cutting the diagonal branches. However, it has the disadvantage of leaving an akinetic area that corresponds to the intracardiac patch. We believe that choice of the LVP method according to the preoperative LV shape will bring about a better postoperative LV function and shape.
