Temporary left ventricular support aims to decompress the left ventricle and provide adequate forward flow into the arterial circulation. This can be accomplished with endovascular devices such as the Impella with an internal motor, or with the implementation of cannulae to drain the left ventricle or left atrium and then return to the arterial circulation using an external pump. In this report, the authors describe the transesophageal echocardiography-guided placement of a single-cannula system with the Protek Duo RD (TandemLife, LivaNova) via a left ventricular apical approach to provide minimally invasive left ventricular support in a high-risk Jehovah's Witness patient.
临时左心室辅助的目的是使左心室减压并为动脉循环提供足够的前向血流。这可以通过内置电机的 Impella 等血管内装置来实现，或者通过实施引流左心室或左心房的插管，然后使用外部泵将其返回到动脉循环。在本报告中，作者描述了经食管超声心动图引导下通过左心室心尖入路放置 Protek Duo RD（TandemLife，LivaNova）单管系统，为高风险的耶和华见证会患者提供微创左心室支持。
