Identification of patients with cardiogenic shock and right ventricle (RV) dysfunction who may require biventricular rather than isolated left ventricular (LV) support remains challenging. In this setting, rigorous hemodynamic evaluation of biventricular contractility and load during initiation of LV support guides therapy. We now report a novel approach to assess biventricular pressure-volume loops in a patient receiving Impella 5.5 support for heart failure and shock.

Impella 5.5 左心室支持对双心室血流动力学的急性影响

识别可能需要双心室而不是孤立的左心室 (LV) 支持的心源性休克和右心室 (RV) 功能障碍患者仍然具有挑战性。在这种情况下，在 LV 支持开始期间对双心室收缩力和负荷进行严格的血流动力学评估以指导治疗。我们现在报告了一种新方法，用于评估接受 Impella 5.5 支持的心力衰竭和休克患者的双心室压力容积环。
