Reference Range for Tissue Motion Tracking of Mitral Annulus Displacement in Chinese Han Singleton Pregnancies

The First Affiliated Hospital of China Medical University initiated a multi-center study on the reference range of tissue motion tracking of mitral annulus displacement in Chinese Han singleton pregnancies to determine the reference range of tissue motion annular displacement (TMAD) in the pregnant population and to promote the clinical application of TMAD in the pregnant population, thereby offering new insights into the early evaluation and early diagnosis for cardiac function in the pregnant population.
