Research Focus

  • Our group is interested in a broad array of clinical and translational investigations spanning the evaluation of basic pathophysiology in patients undergoing cardiac procedures, development and evaluation of new therapeutic strategies, and improving patient selection and outcomes following interventional procedures. We are comprised of a core group of faculty and dedicated research nurses as well as fellows, residents, and students. Projects range from investigator-initiated single-center observational studies to industry-sponsored multicenter phase 3 randomized controlled trials. We have established a database of all patients who have undergone TAVR at Johns Hopkins, which is providing the basis for several retrospective analyses and will serve as the foundation for future studies of TAVR. We are also engaged in collaborative projects with other groups from the Department of Medicine and other Departments including Cardiac Surgery, Anesthesiology, Radiology, Psychiatry, and Biomedical Engineering. Members of our group are actively involved with the Johns Hopkins Center for Bioengineering Innovation and Design (CBID) in the development of novel minimally-invasive cardiovascular devices.
