Pulmonary valve echocardiography has been done in 11 cases of pulmonary hypertension, and 4 cases of right ventricular outflow tract obstruction, either at valvar, infundibular or combined level. Absence of `a' wave was noted in 6 out of 10 cases in whom dia­stolic gradient across the pulmonary valve was more than 25 mm of mercury. Accelerated 'bc' slope was found in all the 11 cases of pulmonary hypertension. Two patients had negative and 6 had flat `ef' slopes. Remaining 3 patients had normal 'ef' slope despite hav­ing moderately severe pulmonary hypertension. Only three of our patients had shown midsystolic closure and fluttering of pulmonary valve. In right ventricular outflow tract obstruction one patient with valvar and infundibular stenosis had shown presystolic opening of the pulmonary valve with fluttering of the leaflets during systole. Three other patients had no remarkable features.
