A 63-year-old man with a newly placed left ventricular assist device (LVAD) was emergently taken to the operating room for mediastinal exploration secondary to worsened LVAD output, hemodynamic instability, and organ hypoperfusion. Intraoperative transesophageal echocardiography showed the LVAD inflow cannula intermittently aspirating the atrial septal wall, resulting in occlusion of the inflow cannula. Upon gradual withdrawal of the inflow cannula by several centimeters, dramatic improvements in LVAD output, hemodynamics, and tissue perfusion occurred. Clinical implications of a patient who has a malfunctioning LVAD are discussed.
一名63岁男性患者，新植入左心室辅助装置（LVAD），因LVAD输出量恶化、血流动力学不稳定和器官灌注不足，紧急送往手术室进行纵隔探查。术中经食管超声心动图显示LVAD流入插管间歇性抽吸房间隔壁，导致流入插管堵塞。将流入插管逐渐回撤几厘米后，LVAD输出量、血流动力学和组织灌注得到显著改善。本文讨论了LVAD出现故障的患者的临床意义。
