Right ventricular assist device (RVAD) implantation is one type of surgical treatment used for right heart failure. It is important to assess right ventricular (RV) function precisely when RVAD withdrawal is considered. Although assessment of RV function is difficult due to its complicated shape and contraction pattern, the volumetric analysis method of three-dimensional (3D) transesophageal echocardiography (TEE) has been developed and is useful for this task. We report the case of a 79-year-old man who successfully underwent RVAD withdrawal and evaluation using 3D TEE. 3D TEE had an important role in determining the timing of withdrawal from RVAD in this case.
右心室辅助装置（RVAD）植入是用于治疗右心衰竭的一种外科治疗方法。在考虑撤除RVAD时，准确评估右心室（RV）功能非常重要。尽管由于RV形状复杂和收缩模式，评估RV功能具有挑战性，但三维（3D）经食管超声心动图（TEE）的容积分析方法已被开发出来，并且对于这项任务很有用。我们报告了一例79岁男性患者成功撤除RVAD并使用3D TEE进行评估的病例。在该病例中，3D TEE在确定撤除RVAD的时机方面发挥了重要作用。
