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 with 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 considerable histological changes were part of right ventricular dysplasia or not. The present case indicates that even with normal LV shape and function in patients with right ventricular dysplasia, histological examination of LV may provide additional information on its pathogenesis and prognosis.
