Clinical Interests

Thomas Smith is a specialist in cardiovascular imaging utilizing multiple techniques including echocardiography (transesophageal and transthoracic), computed tomography, nuclear medicine and magnetic resonance imaging to evaluate cardiac structure and function.

He completed his general cardiology fellowship here at UC Davis with additional, advanced training at Cedars Sinai.  Currently, he is the Director of the Adult Echocardiography Laboratory.  

His clinical interests include echocardiographic guidance of minimally invasive cardiac procedures, cardiac computed tomography,  valvular heart disease and prevention of coronary artery disease.

Research/Academic Interests

Dr. Smith is active in multiple research studies focusing on transcatheter aortic valve replacement and transcatheter mitral valve repair.  He is also involved in research studies using specialized blood tests and nuclear imaging to evaluate the heart muscle following myocardial infarctions.
