Rare fellowship opportunity in experimental structural heart intervention

The Organization

The Laboratory of Cardiovascular Intervention at the NHLBI Division of Intramural Research is located at the NIH Campus in Bethesda Maryland USA. Our lab conceives new image-guided structural heart and valve interventional procedures and helps to bring them into clinical practice at cooperating medical centers. Our group has created transcaval access and closure, LAMPOON and ELASTIC mitral leaflet modification; BASILICA aortic leaflet modification; mitral cerclage; TRAIPTA tricuspid annuloplasty, clinical MRI catheterization, and others currently under development. The facility has a dedicated biplane X-ray and (novel high-performance low-field) MRI interventional suite used primarily for large-animal experiments. Our dedicated team includes engineers, physicists, technologists, nurses, adult and pediatric cardiologists, and other staff. We work closely with advanced structural heart programs, especially Emory University (Greenbaum and Babaliaros) and Medstar Washington Hospital Center (Rogers), to bring our technologies into patients. However there are only limited opportunities to practice interventional cardiology during this fellowship.

Usually the lab has only one full-time fellow and a several part-time alumni. Few cardiologists ever in their lifetimes have the opportunity to participate in the conception of a new procedure and its first application to patients. Our fellows typically do this more than once, and on projects they themselves lead. Recent fellows and alumni had little prior publication record but have made remarkable contributions to medicine during their tenures: Toby Rogers, Jaffar M. Khan, Christopher G. Bruce, Kanishka Ratnayaka. Search pubmed for examples. We don’t bloviate or twit about innovation; instead we create new procedures, techniques, and devices and then we evaluate and disseminate our findings.

The Role

We seek talented individuals for extended research fellowships in developing novel image-guided structural heart interventional procedures. Effort is directed at conducting science and not applying for funding. Fellows are expected to lead comprehensive projects from concept to preclinical to early clinical.

About You

Ideal candidates are resourceful, hardworking, inquisitive, and well-read, and have advanced clinical cardiovascular catheterization training up to and including PCI, as well as training and experience in CT and CMR acquisition and processing. Candidates must be eligible for USMLE/ECFMG licensure to practice medicine in at least one US state. We take for granted that candidates are superb physicians with outstanding judgement and highest moral caliber. Ideally candidates have the support of home or other “destination” academic centers where they can return or establish independent research/clinical programs after finishing at NHLBI. Once eligible, fellows are promoted to Staff Clinician with attendant salary increase. Our laboratory is very family-friendly.


One or two positions may become available in 2022-2023. If you are interested, please identify trusted supervisors who can attest to your potential, and send your CV to Robert J. Lederman, MD,
