Despite advancements in mechanical circulatory support (MCS) technology, persistent critical complications related to blood contact remain unresolved. To provide a safer alternative therapy, CorInnova is developing a non-blood contacting direct cardiac compression (DCC) device for MCS. To support product development toward clinical trials, a simulation platform has been developed to predict clinical outcomes under patient-specific conditions, guiding patient selection for clinical trials. The Harvi simulation was validated using preclinical in vivo data from experimental studies with the CorInnova device, with n = 28 hemodynamic samples simulated from animal data (n = 4 ovine). After confirming validation, further simulation was performed to predict additional hemodynamic outcomes not captured in animal studies. The simulated effects of CorInnova device therapy were not significantly different from animal data for cardiac output, systemic arterial blood pressure, mean pulmonary artery pressure, central venous pressure, or left ventricular pressure ( p > 0.050). Harvi accurately predicts the effects of the CorInnova device in heart failure conditions and can be used in preparation for future clinical trials.
尽管机械循环支持(MCS)技术取得了进展,但与血液接触相关的持续性严重并发症仍未得到解决。为了提供一种更安全的替代疗法,CorInnova公司正在开发一种用于MCS的非血液接触式直接心脏按压(DCC)设备。为了支持产品向临床试验方向发展,已开发了一个模拟平台,以预测特定患者条件下的临床结果,指导临床试验的患者选择。使用来自CorInnova设备实验研究的临床前体内数据对Harvi模拟进行了验证,从动物数据(n = 4只绵羊)模拟了n = 28个血流动力学样本。在确认验证后,进行了进一步模拟,以预测动物研究中未捕获的其他血流动力学结果。CorInnova设备治疗的模拟效果与动物数据在心输出量、体动脉血压、平均肺动脉压、中心静脉压或左心室压力方面无显著差异(p > 0.050)。Harvi能够准确预测CorInnova设备在心力衰竭情况下的效果,可用于为未来的临床试验做准备。
