Goal 2: Reduce Human Disease

How can we non-invasively, but still accurately, measure blood pressure in the pulmonary arteries?

Pulmonary hypertension (PH) is a complex, progressive condition characterized by high blood pressure in the lungs. The gold standard for measuring pressures in the pulmonary arteries is a right heart catheterization, where a special catheter is guided through the right side of the heart and into the pulmonary artery, the main vessel carrying blood to the lungs. This measurement is essential, as it allows physicians and patients to accurately diagnose the disease and to select the most appropriate treatment. Other, less invasive methods—such as echocardiography, CT scan, and MRI—do not yet indirectly measure pulmonary artery pressure as accurately as the right heart catheterization.
