Pulmonary Vascular Program

Pulmonary Vascular Program

The Pulmonary Vascular Program at Cleveland Clinic consists of a team of 7 pulmonologists, 2 cardiologists, 2 advanced practice nurses, a nurse, 2 program coordinators, and 2 research coordinators. Additionally, as part of Cleveland Clinic, the program draws on expertise in cardiology, cardiothoracic surgery, lung transplantation, hepatology, liver transplantation, sleep medicine, rheumatology, hematology, and interventional radiology to provide a comprehensive and multidisciplinary approach to patient care. The program has dedicated multidisciplinary teams to care for patients with chronic thromboembolic pulmonary hypertension, hereditary hemorrhagic telangiectasia, congenital heart disease, pulmonary hypertension associated with the scleroderma spectrum of diseases and other connective tissue diseases, pulmonary hypertension associated with interstitial lung disease and chronic obstructive lung disease, portopulmonary hypertension, and sickle cell disease. The program offers advanced hemodynamic evaluation including invasive cardiopulmonary exercise testing (ie, simultaneous right heart catheterization and cardiopulmonary exercise testing) and maintains an Institutional Review Board-approved comprehensive registry.

The Pulmonary Vascular Program is involved in a wide range of research activities, from NIH-funded basic research and translational research to clinical trials of the latest therapies. Many patients referred to the program benefit from enrollment in 1 or more of these ongoing clinical trials and research studies.

CPET = cardiopulmonary exercise test, esoph = esophageal

The number of pulmonary artery catheterizations (standard, with vaso-reactivity testing using nitric oxide, with exercise, with concomitant CPET, and with esophageal probe performed at the Respiratory Institute has increased each year and has more than doubled since 2015. In addition, an increasing number of procedures include advanced techniques such as invasive CPET.
