3D Echo Evaluation of the Ventricles in Sclero Associated Severe PAH

Study Purpose

The aim of the study is to document the left and right ventricular function in patients with sclerodermia associated pulmonal arterial hypertension via 3D echocardiography. The results of this study should help to generate hypothesis for further future studies. The primary hypothesis is that the increased use of modern image guided methods could provide essential aspects for the follow up.

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.

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.

Pulmonary Arterial Hypertension
Additional Details

The 3D echocardiography could provide early and detailed information about the changes in the left and right ventricle. The prediction of sclerodermia associated pulmonary arterial hypertension (PAH) is rather adverse, so it makes sense to evaluate relevant changes of the left-ventricular longitudinal strain soon to adapt the PAH specific therapy accordingly.
