Transthoracic Doppler echocardiography continues to play a predominant role in the evaluation of patients with valvular heart disease. Current efforts in the research arena have been focused on improving the accuracy of techniques, as well as in further describing the shortcomings. Accurate quantitation of valvular regurgitation continues to be a major stumbling block. However, more sophisticated techniques are being successfully applied to obviate some of the limitations of color flow imaging. Transesophageal echocardiography has provided a new window and clarity of resolution that greatly facilitates evaluation of valvular heart disease in cases where the transthoracic approach is limited, particularly in patients with prosthetic valves.
经胸多普勒超声心动图在心脏瓣膜病患者的评估中仍发挥着主要作用。目前研究领域的工作重点是提高技术的准确性，并进一步描述其缺点。瓣膜反流的准确量化仍然是一个主要障碍。然而，更复杂的技术正在成功应用，以消除彩色血流成像的一些局限性。经食管超声心动图提供了一个新的窗口和更高的分辨率，在经胸途径受限的情况下，极大地促进了心脏瓣膜病的评估，特别是在人工瓣膜患者中。
