Lateral Suture. The lateral border zone between fibrotic and normal tissue of the ventricular wall is secured to the superior (lateral) rim of the patch (patch-tissue mismatch). Panels A and B depict the stretching of the suture that approaches and fits the lateral wall to the patch. The arrow in panel B shows how the suture redirects fiber orientation, approaching a farer point of the myocardial wall to a nearer point on the patch.
