5. Study Description
Brief Summary
The purpose of this Trial is to demonstrate the safety and effectiveness of the use of Impella 5.5 in high-risk cardiac surgery patients, with the overall aim to evaluate if using Impella 5.5 with SmartAssist (Impella 5.5) peri-operatively improves early hemodynamics, end-organ function and clinical outcomes in patients with severely reduced LV function undergoing cardiac surgery.
Detailed Description
This is a prospective single-armed Trial to demonstrate the safety and effectiveness of the use of Impella 5.5 in high-risk cardiac surgery patients. A concurrent Registry will also be performed to collect information on patients meeting Exclusion Criteria and those not approached for enrollment. The overall aim is to evaluate the safety and effectiveness of using Impella 5.5 preemptively in high-risk cardiac surgery patients with severe LV dysfunction. This Trial will determine whether using the Impella 5.5 in this setting will result in an acceptable device-related safety profile.
