Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion criteria:

  • Age > 18 years
  • Diagnosis of Group 1 or Group 4 PAH based on PAPm > 25 mmHg, PAWP <15 mmHg, PVR >3 WU and consistent clinical history. Note: for logistical reasons, patients at high suspicion for Group 1 or Group 4 PAH will sign informed consent to have the USCOM system applied during right heart catheterization before the procedure; if it is found that the patient does not meet the definition of Group 1 or Group 4 PAH during right heart catheterization, he/she will be excluded.
  • Willingness and ability to comply with study procedures.
  • No known hypersensitivity to the components of USCOM electrodes

Exclusion criteria:

  • Unwillingness to sign informed consent or inability or unwillingness to comply with study procedures
  • Evidence of postcapillary pulmonary hypertension on right heart catheterization
