Clinical Trials

Has your doctor recommended right heart cardiac catheterization for you? This study is investigating new magnetic resonance imaging (MRI) techniques that use a guidewire to help position a heart catheter within the heart. MRI fluoroscopy shows pictures of the heart so that doctors can watch while they work. Using the guidewire during MRI may improve the procedure of heart catheterization. To participate in this study, you must be at least 18 years old, and your doctor must have recommended right heart catheterization for you. This study is located in Bethesda, Maryland.

The purpose of this study is to see if adding a drug called Regadenoson to the EVLP circulation reservoir during perfusion of marginal donor lungs will help increase the likelihood that the donor lungs will become usable for transplantation.

This project will determine the health impact of parenthood on people with cystic fibrosis (CF). The study team will use retrospective data to provide relatively immediate evidence on parenthood's effect on pulmonary health.

Do you or your child have a lung disease? This study will investigate the genes involved in the breathing process and in the development of lung diseases such as asthma or sarcoidosis to improve understanding of the role they play. To participate in this study, you or your child must be between 2 and 90 years old. This study is located in Bethesda, Maryland, at the NIH Clinical Center.

Are you in need of a heart or lung transplant or have you had one in the past 3 months? Have you undergone a lung or heart transplant in the past 3 months or are you a candidate for heart or lung transplant? Some people with advanced heart and lung disease have heart and lung transplants but these new organs are often rejected. When this happens, patients must have repeated biopsies, which are invasive and expensive. Researchers in this clinical study want to see if a blood test can predict organ rejection and take the place of biopsies. To participate, you must be 18 to 80 years old and be a candidate for heart or lung transplant or have had a heart or lung transplant no more than three months ago. The study is taking place in Bethesda, Maryland, at the NIH Clinical Center, as well as in Baltimore, Maryland, and Falls Church, Virginia.

Did you develop atrial fibrillation after coronary artery bypass graft (CABG) surgery? Did you develop atrial fibrillation after a coronary artery bypass grafting (CABG) surgery? This study is looking at how well oral anticoagulation medicines work to prevent complications, such as blood clots and heart attack, for patients who experience post-operative atrial fibrillation (POAF). This study is in multiple locations around the country.
