Thomas John Ryan
Instructor in the Department of Medicine
The research activities of the Echo Lab focus on clinical application of ultrasound techniques in a variety of situations. While we have an interest in several areas of clinical echocardiography, much of the focus of the laboratory is placed in the areas of 3-dimensional imaging, contrast echocardiography, endocarditis, and stress echo.
The specific approach of our research goals deals with the application of newer echocardiographic techniques to clinical diagnosis. For example, we are currently working on the use of real-time 3-dimensional echocardiography for the assessment of left ventricular function and for quantitation of various parameters of myocardial performance.
In the area of clinical trials, we are actively involved in several ongoing studies examining the use of left heart contrast agents for evaluating left ventricular function and myocardial perfusion, in conjunction with stress echocardiography. We are also beginning a multicenter trial on the use of pharmacologic stress testing for preoperative evaluation of patients undergoing noncardiac surgery.
My primary area of expertise involves stress echocardiography. I have published extensively in this area and lecture widely on these topics. I have, over the part few years, written several book chapters in cardiology textbooks on the topic of stress echocardiography.
Key words: Echocardiography, Stress Echocardiography, 3-Dimensional Echocardiography, Contrast Echocardiography
