Khanna] Pulmonary hypertension is the usual sequelae of rheumatic mitral valve disease. The histological change of pulmonary vessels in the lung biopsies of 50 patients of rheumatic mitral valve disease were evaluated and correlated with clinical grading of pulmonary hypertension. Medial hypertrophy of muscular arteries was present in 40 out of 50 cases. Intimai proliferation was present in 12 cases. Necrotizing arteritis was seen in one case. Dilation and angiomatold lesions were not observed. Disparity in the histological findings of pulmonary vessels in lung biopsies and haemodynamic data was observed in large number of cases. Although it is generally believed that pulmonary hypertension in rheumatic mitral valve disease is severe in Indian population, our data suggests that histological change of pulmonary vasculature in these cases are akin to those observed in the west and do not reveal a very severe pulmonary hypertension.
