Pressure-Volume Loop During High-Risk PCI

Given the complexity of patients treated by high risk percutaneous coronary interventions (HRPCI), mechanical circulatory support (MCS) devices are increasingly used to maintain hemodynamic stability during these procedures. It is crucial to have a better understanding of the hemodynamic effects during HRPCI and of MCS devices to guide appropriate device selection and utilization for HRPCI.

Clinical studies evaluating different MCS devices are not all consistent in terms of patient selection, outcomes examined and overall findings. Therefore, the role of MCS devices in HRPCI is still widely debated. This is reflected in a variable clinical practice pattern and recommendations from professional society guidelines. The investigators believe that having a clear scientific understanding of MCS devices in terms of hemodynamic effects during different stages of these complex procedures may prove helpful in refining the process of appropriate MCS device selection in appropriate clinical setting.

One especially insightful method of examining the MCS devices effect is analyzing the left ventricular (LV) pressure-volume loops (PVL). Continuously recording PVL during HRPCI can provide valuable data on the device effects on loading conditions and contractility of the left ventricle.

In this study, the investigators will collect hemodynamic data in real-time during HRPCI being performed as standard of care and continuously recording left ventricular pressure-volume loop (PVL) throughout the procedure via the Inca® Pressure-Volume Loop System (CD Leycom, Hengelo, The Netherlands).
