A biatrial dual‑lumen catheter to help the heart and lungs in pulmonary arterial hypertension
The Development of a Biatrial Catheter for a Cardiopulmonary Support System in Pulmonary Arterial Hypertension
A new double‑lumen catheter is being developed to unload the right side of the heart and protect the lungs for people with pulmonary arterial hypertension.

What this research studies
You would be offered a device that uses two channels and sits across the upper chambers of the heart to divert blood and reduce strain on the right ventricle. The team plans to design a way to anchor the catheter for long‑term use and build in sensors to monitor and control blood flow. Work will start with lab and animal testing and progress toward carefully monitored human use to check safety and function. The hope is this approach could keep you stable long enough for medical treatment to work or while waiting for a lung transplant.
Who could benefit from this research
Good fit: Ideal candidates would be people with severe pulmonary arterial hypertension with right‑heart strain or failure who are not well controlled by medicines and who may be awaiting lung transplant.
Not a fit: Patients whose symptoms are caused mainly by left‑sided heart disease, those with active infections, or who cannot tolerate catheter placement are unlikely to benefit.
Why it matters
Potential benefit: If successful, this device could lower pressure on the right heart and lungs, prolong survival, and give patients more time to respond to medicines or reach transplant.
How similar studies have performed: While other right‑heart support devices and interatrial approaches exist, this specific biatrial dual‑lumen catheter design is novel and largely untested in humans.
