3D Imaging: Prognostic Role in Pulmonary Arterial Hypertension

Study Purpose

Pulmonary hypertension is a rare and severe disease, affecting a young population. Survival is very poor and has been closely related to right ventricular dysfunction. Current prognostic equations rely mostly on right heart catheterization data. The identification of simple echocardiographic prognostic factor is urgently needed. It could help identifying with a non invasive method, high risk patients who could benefit from an intensive specific therapy. 3D right ventricular imaging is a new echocardiographic tool which provides RV volumic analysis, RV ejection fraction, overcoming the classical limits of 2D ultrasound. The aim of this study is to validate a new software for 3D analysis of the right ventricle and assess its prognostic role in pulmonary hypertension. To do so, the investigators will realize a prospective monocentric longitudinal cohort study, including 100 pulmonary hypertension patients. Echocardiographic data will be collected at baseline and after 6 months.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Study Type

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.

Eligible Ages 18 Years and Over
Gender All
More Inclusion & Exclusion Criteria

Inclusion Criteria:

- Patients > 18 years old - Pulmonary hypertension diagnosed by right heart catheterization - Informed consent obtained - Affiliation to the French national health insurance

Exclusion Criteria:

- Associated significant left heart disease - Sub-optimal acoustic windows - Patient unable to attend follow-up visits

Trial Details

Trial ID:

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.
