摘  要: Trabeculae carneae are considered embryologic remnants that play no functional role in the adult heart. Thickening of the ventricular wall and the trabeculae carneae as well as fibrosis of trabeculae carneae occurs in LV hypertrophy but its role in cardiac function remains unclear. The objectives of our study are to characterize the mechanical properties of trabeculae carneae and determine the contribution of trabeculae carneae to the LV diastolic compliance. Our results demonstrated that trabeculae carneae is softer than the myocardium and cutting trabeculae carneae increases the LV compliance in human hearts. These results suggest that cutting LV trabeculae carneae could be a potential approach to treat patients with diastolic heart failure.

Information about graduate programs and opportunities at UTSA for graduate student exchange will be discussed.

Short Bio.

Dr. Han is the Zachry Endowed Chair Professor and Department Chair of Mechanical Engineering at the University of Texas at San Antonio (UTSA). He received his Ph.D. degree in Solid Mechanics/Biomechanics in 1991 from Xi’an Jiaotong University in China with joint training from the University of California at San Diego under the tutelage of Professor YC Fung. Dr. Han was an Associate Professor at Xi’an Jiaotong University and a Research Engineer II at Georgia Institute of Technology before joining UTSA in 2003.

Dr. Han’s research interests are in the area of cardiovascular biomechanics with focus on arterial wall mechanical and instability, cardiac mechanics, and tissue remodeling. He has published over 100 peer-reviewed journal papers. He received a CAREER award from NSF in 2007. He is a Fellow of American Heart Association (AHA), College of Fellows of American Institute for Medical and Biological Engineering (AIMBE), and American Society of Mechanical Engineers (ASME). He is an Associate Editor of the ASME Journal of Biomechanical Engineering and a member of editorial boards of a number of journals.
