Occurrence of acute right heart failure (ARHF) remains common during pulmonary hypertension
(PH). Right atrial pressure (RAP) invasive measurement is the gold standard to diagnose ARHF
in order to improve diuretic treatment management. Existence of indirect signs of ARHF on
venous Doppler ultrasound waveform has long been described, but correlation with RAP has not
been properly established yet. It is the aim of our study in order to obtain an additional
tool to manage ARHF.
Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms
An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.
An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.
Searching Both is inclusive of interventional and observational studies.
This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.
Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.
Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.
Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.
Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.
The sponsor is the organization or person who oversees the clinical study and is responsible for analyzing the study data.

Category of organization(s) involved as sponsor (and collaborator) supporting the trial.
The disease, disorder, syndrome, illness, or injury that is being studied.
Experimental: Peripheral veins Doppler ultrasound
Diagnostic Test: - Peripheral veins Doppler ultrasound
Patients undergoing a right heart catheterization for PH diagnosis or annual follow-up in the cardiological unit of the university hospital of Poitiers will be included. A venous Doppler ultrasound will be performed by a vascular physician, with experience in vascular ultrasound imaging, within 4 hours before the right heart catheterization. Morphological parameters of vena cava, and velocimetric parameters of femoral, jugular and supra-hepatic veins will be assessed in order to study their correlation with right auricular pressure value.
