RIGHT VENTRICULAR PERFORATION Figure 24-19 RIGHT VENTRICULAR PERFORATION The presence of fibroadipose tissue and mesothelial lining in an endomyocardial biopsy typically indicates perforation. However, most of the time this is of no clinical consequence and heals spontaneously. More about this image found in RIGHT VENTRICULAR PERFORATION The presence of fibroadipose tissue and meso...
