Held as part of the Pulmonary Hypertension Association’s International PH Conference, the Scientific Sessions bring together clinicians and researchers to share the latest in pulmonary hypertension, improve patient care and earn CME/CE credit. Open to health care professionals across disciplines and career stages, the sessions focus on practical, evidence-based approaches and foster cross-disciplinary collaboration.

The program features expert-led presentations, debates, poster sessions and interactive discussions on the latest in PH research and treatment, including:

  • Pathophysiology and disease mechanisms.
  • Diagnosis, risk assessment and screening.
  • Therapeutic strategies and emerging treatments.
  • Pediatric PH.
  • Health disparities and social determinants of health.
  • Registries and real-world evidence.

The research poster hall showcases basic science, clinical science and case reports from PH professionals. Selected abstracts may be published in Advances in Pulmonary Hypertension, PHA’s peer-reviewed journal.

Session proposals and abstract submissions

Health care professionals are invited to share their expertise by submitting session proposals or research abstracts.

  • Session proposals: The Scientific Sessions Committee seeks proposals that explore current topics in clinical practice, interdisciplinary care and innovation in PH.
  • Abstract submissions: Abstracts are accepted in basic science, clinical science or case reports.

Abstracts and session proposals for the 2026 Scientific Sessions are now being accepted. The target audience will be a mixture of new and experienced PH-treating health care professionals of varying disciplines.

Session Proposals: The 2026 Scientific Sessions Subcommittee invites session proposal submissions to present during CME/CE accredited sessions during the 2026 Scientific Sessions. Potential topics may include, but are not limited to:
•    Sotatercept use and response in PAH
•    Remote monitoring and wearables in PH
•    Novel phenotyping approaches in PH
•    Integrative physiology in PH: Beyond the heart and lungs
•    Novel treatment approaches for PAH and other PH subtypes

If your proposal is accepted by the 2026 Scientific Sessions Subcommittee, you will be invited to present it during one of the Scientific Sessions. Session proposals are due by Monday, December 8, 2025.

Poster abstracts: The Conference will feature a poster hall in conjunction with its medical education activities.
