Perfusion Mode

Cardiac assist devices (CAD) cause endothelial dysfunction with considerable morbidity. Employment of pulsatile CAD remains controversial due to inadequate perfusion curves and costs. Alternatively, we are proposing a new concept of pulsatile CAD based on a fundamental revision of the entire circulatory system in correspondence with the physiopathology and law of physics. It concerns a double lumen disposable tube device that could be adapted to conventional cardiopulmonary bypass (CPB) and/or CAD, for inducing a homogenous, downstream pulsatile perfusion mode with lower energy losses. In this study, the device’s prototypes were tested in a simulated conventional pediatric CPB circuit for energy losses and as a left ventricular assist device (LVAD) in ischemic piglets model for endothelial shear stress (ESS) evaluations. In conclusion and according to the study results the pulsatile tube was successfully capable of transforming a conventional CPB and/or CAD steady flow into a pulsatile perfusion mode, with nearly physiologic pulse pressure and lower energy losses. This represents a cost-effective promising method with low mortality and morbidity, especially in fragile cardiac patients.

Haemodynamic Improvement

The experience and usage of percutaneous cardiac assist devices in cardiogenic shock as well as high-risk percutaneous coronary intervention have increased over the years. Nonetheless, there is still little evidence of clinical benefit of these devices other than immediate haemodynamic improvement. Despite the fact that these devices are used to treat a rather complex patient population, clinical testing remains important in order to evaluate their true impact on clinical outcome before being adopted into clinical practice. Therefore, this review shows an overview of the current experience and evidence of the available percutaneous cardiac assist devices.
