At the beginning of this presentation, the pulmonary hypertension was classified into three groups as follows : 1) Pulmonary pulmonary hypertension 2) Pulmonary hypertension in congenital cardiovascular disease 3) Pulmonary hypertension due to the left heart disease This (3) pulmonary hypertension due to the left heart disorder corresponds to the passive pulmonary hypertension (Wood, P.) and is accompanied by the elevation of the pulmonary venous pressure. Pulmonary hypertension due to left to right shunt in congenital cardiovascular disease (2) is equivalent to the hyperkinetic pulmonary hypertension. And pulmonary pulmonary hypertension (1) is caused by the disease of the lung and/or thorax and has possibility to develop the pulmonary heart disease defined by WHO.
