HISTOLOGICAL ABNORMALITIES IN A BIOPSY SPECIMEN OBTAINED FROM THE LEFT-VENTRICLE WITHOUT REDUCED FUNCTION IN A PATIENT WITH RIGHT-VENTRICULAR DYSPLASIA

Left ventricular histological examination was performed in a patient w ith right ventricular (RV) dysplasia. Although the left ventricle (LV) appeared to have a normal shape and function, the LV biopsy specimen revealed apparent myocyte hypertrophy and substantial fibrotic changes without fatty infiltration. It was not clear whether these considerab le histological changes were part of right ventricular dysplasia or no t. The present case indicates that even with normal LV shape and funct ion in patients with right ventricular dysplasia, hitological examinat ion of LV may provide additional information on its pathogenesis and p rognosis.
