This laboratory is principally interested in investigation of issues related to congenital heart surgery. Because of the multidisciplinary nature of this field and in order to enhance the relevance and quality of the research performed, the laboratory benefits from the participation of faculty from pediatric cardiac surgery, pediatric cardiac anesthesiology and critical care medicine, and pediatric cardiology. Surgical residents interested in working in this laboratory will be principally under the supervision of Dr. James Jaggers in the Division of Pediatric Cardiac Surgery. More »

The Cardiovascular Function sub-unit of the Cardiothoracic Research Laboratory is devoted to the study of basic cardiopulmonary physiology in its application to clinically relevant problems. Chronically instrumented conscious animals are generally used in conjunction with a wide variety of state-of-the-art data collection and analysis techniques. Study methods include pulse transient sonmicrometry for dimensional analysis of global and regional ventricular geometry, high fidelity micromanometry, Doppler measurement of aortic, pulmonary, and coronary blood flow, 2-dimensional echocardiography for measuring left ventricular wall mass, color flow echocardiographic assessment of valvular lesions, 3-dimensional echocardiography, cardiac catheterization for coronary sinus and coronary artery instrumentation, on-line venous and arterial oxygen saturation for renal time oxygen consumption analysis, and ventricular thermo dilution calorimetry.

Both as the Mary and Deryl Hart Professor of Surgery and Chief Medical Officer of Duke University Medical Center, a major interest of Robert H. Jones is in enhancing value of healthcare. Value implies best quality for least cost. Understanding quality requires measurement of important outcomes, processes, and structure of healthcare delivery. Costs of concern relate both to resource consumption and negative outcomes of treatment. More »
