I have severe pulmonary arterial hypertension. My echo done two days ago state
Dear Susan, There are two ways to measure right ventricular dimensions. They measure from different places, and there are different cuts of values for each measurement. Most probably the last time they measured right ventricular size from apical view, so 31 mm was quite normal finding, and this time they measured from paternal view, so it is dilated, so the absolute value is small but for that view it is dilated. We shouldn't forget, that our heart is a 3D geometrical structure, that's why it depends on which diameter we take, and there are different values for different cut planes. Take fearsome back if you have any further questions
