Abstract

The left ventricular reconstruction (LVR) with endoventricular circular patch plasty (EVCPP) was reported in 1984 as a surgical method to rebuild left ventricular aneurysm or asynergy after myocardial infarction. Scarred LV wall can be dyskinetic or akinetic according to the type of infarction (transmural or not), and the progressive dilatation of LV (remodeling) depends on the size of the asynergic scar. Assessment of this extension and of LV volume and performances, is easy and reliable by magnetic resonance (CMR). The surgical technique is based on the insertion inside the ventricle on contractile myocardium, of a circular patch restoring curvature and physiological volume, and allowing exclusion of asynergic non resectable regions. The ventricular reconstruction method also has other components that include coronary revascularization (almost always), mitral repair (if needed) and endocardectomy when spontaneous or inducible ventricular tachycardia (VT) are present. The experience of the authors (> 1100 cases) and results obtained by other Centers, allows proposal of this technique as a way to treat the ischemic failing ventricle.
