Cardiovascular Core Lab team member looking at cardiovascular imageThe Cardiovascular Core Laboratories at the MedStar Health Research Institute is an academic cardiovascular imaging Core Lab which provides internationally recognized expertise in an efficient and responsive environment. We recognize the demands placed on sponsors and pride ourselves on having the perfect blend of academic integrity and operational efficiency, unparalleled by any commercial lab. How do we do this? It is simple - we approach every new study as we would a new patient. We seek to understand the study, it's background and what it is trying to accomplish. Then we offer our experience and expertise in medical imaging to help guide the study to effectively and efficiently reach its endpoints.

The Cardiovascular Core Labs consists of the Echocardiography Core Lab, the Cardiac MRI Core Lab, and the Cardiac CT Core Lab. We have participated in a wide range of clinical trials on such topics as:

  • Innovative therapeutics and assessment for structural heart diseases such as aortic valve stenosis and mitral valve regurgitation. We have provided assessment for implantable cardiac devices like transcatheter aortic valve replacement (TAVR), transcatheter mitral valve replacement (TMVR) and pulmonary investigational replacement valves.
  • Ischemic cardiomyopathies studies focus on coronary plaque assessment by CTA and calcium scoring.
  • Congenital and/or genetically triggered cardiovascular diseases like Marfan’s Syndrome or other congenital connective tissue diseases.
  • Stem cells and other pharmaceutical therapy for cardiovascular diseases.

Our Laboratories 


Under the direction of Dr. Federico M. Asch and Dr. Neil Weissman, the Echocardiography Core Lab provides interpretation and analysis for all types of cardiac ultrasound images including transthoracic, transesophageal/intraoperative, intracardiac, epicardial echocardiography and 3D TEE.

Cardiac CT

Under the direction of Dr. Gaby Weissman, cardiac CT is the latest and one of the most exciting imaging modalities introduced into the cardiac arena. CT has well established role for pericardial disease, coronary pathology, calcium detection and now multi-slice CT is rapidly gaining acceptance for myocardial, coronary arterial imaging and prosthetic valve assessment.

Cardiac MRI

Under the direction of Dr. Gaby Weissman, cardiac MRI is an ideal imaging tool that provides high resolution images to assess left ventricular volumes, mass, flow and function (perfusion).
