High Prevalence of Occult Pulmonary Venous Hypertension Revealed by Fluid Challenge in Pulmonary Hypertension Robbins et al: Fluid Challenge in Pulmonary Hypertension

Assessment of pulmonary valve echogram in normal subjects and in patients with pulmonary arterial hypertension.

To assess the validity of ultrasound criteria for pulmonary arterial hypertension, we studied pulmonary valve motion in 28 patients and 20 normal subjects. In the latter group, we categorised normal movement of the posterior leaflet of the pulmonary valve in a fashion not previously described. Of the 28 patients, 19 had pulmonary arterial hypertension (pulmonary artery mean pressure more than 2...

High prevalence of occult pulmonary venous hypertension revealed by fluid challenge in pulmonary hypertension.

BACKGROUND Determining the cause for pulmonary hypertension is difficult in many patients. Pulmonary arterial hypertension (PAH) is differentiated from pulmonary venous hypertension (PVH) by a wedge pressure (PWP)>15 mm Hg in PVH. Patients undergoing right heart catheterization for evaluation of pulmonary hypertension may be dehydrated and have reduced intravascular volume, potentially leading ...

Evaluation of Pulmonary Hypertension In First Degree Relatives Of Patients With Primary Pulmonary Hypertension

Background: Pulmonary hypertension (PH) was defined for the first time in 1951 as primary pulmonary hypertension (PPH). Some studies emphasized on the role of genetics in the development of pulmonary hypertension in family members of affected patients. So, in this study we evaluated the prevalence of pulmonary hypertension in first degree family of patients with documented PPH. Methods: In thi...
