Have you or a family member been diagnosed with CTEPH?

CTEPH is a condition that may develop in patients who have had a pulmonary embolism (PE). About five percent of patients who have experienced PE develop chronic blood clots in the lungs, also known as CTEPH. These chronic blood clots can lead to complications including heart failure and pulmonary hypertension, however, CTEPH can be managed with proper diagnosis and treatment. 

At Northwestern Medicine, patients with CTEPH have access to our multidisciplinary CTEPH program, the largest program of its kind in Illinois. We are also one of the few programs in the nation to offer both of the leading treatment options for CTEPH: pulmonary thromboendarterectomy surgery (PTE) and balloon pulmonary angioplasty (BPA).

How is CTEPH treated?

Medical Management: Blood thinning medications help prevent new blood clots from forming in the lungs. Additional medications are available to help manage CTEPH symptoms. 

Balloon Pulmonary Angioplasty (BPA): BPA is a minimally invasive, catheter-based procedure. BPA moves blood clots out of the way to help restore normal blood flow to the lung.

CTEPH clinical trial options 
Researchers at Northwestern Medicine conduct clinical trials that provide access to innovative therapies for the treatment of CTEPH. Participating in a clinical trial is an opportunity to evaluate the effectiveness and safety of medications or study devices. The following clinical trials are investigational (experimental), which means they are not approved for commercial use by the U.S. FDA. 

Right Ventricular Ischemia and Fibrosis in Chronic Thromboembolic Pulmonary Hypertension (CTEPH): This project is enrolling participants diagnosed with CTEPH who are scheduled for a PTE or BPA procedure for treatment. Eligible participants will undergo a cardiac magnetic resonance imaging (MRI) stress test (also known as stress CMR) before treatment and 6 months after treatment to look at changes in heart function and blood flow.

Pulmonary Thromboendarterectomy Surgery (PTE): PTE is an open surgical procedure. PTE removes blood clots to help restore normal blood flow to the lung. This surgery is considered to be the gold standard for restoring blood flow to the lung.
