Harvi Cardiovascular Modeling Accurately Predicts Hemodynamic Improvements Produced by a New Direct Cardiac Compression Device.

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.
