Impella ECP Early Feasibility Study — ECP EFS  

High-risk Percutaneous Coronary Intervention Clinical Trial

Official title: Use of the Impella ECP in Patients Undergoing an Elective High-Risk Percutaneous Coronary Intervention: An Early Feasibility Study

Status Active, not recruiting

Clinical Trial Summary

The Impella ECP EFS is a prospective, multicenter, single-arm, feasibility study evaluating the safety of the Impella ECP device in adult patients undergoing an elective high-risk percutaneous coronary intervention.

Clinical Trial Description

This is a prospective, multicenter, single-arm, feasibility study evaluating the safety of the Impella ECP device in adult patients undergoing an elective high-risk percutaneous coronary intervention (HRPCI). Additionally, this study will evaluate the feasibility of placing the ECP pump across the aortic valve without the use of a guidewire and assess the ability of the pump to provide sufficient hemodynamic support during a HRPCI. Investigational device products include: Impella ECP pump system (a percutaneous transvalvular micro-axial blood pump), 9Fr introducer sheath, and the automated Impella controller with revised console software to allow control of the Impella ECP.

Following informed consent, subjects eligible for a HRPCI that meet all of the inclusion and none of the exclusion criteria will be enrolled into the study. The intended coronary intervention is then carried out under mechanical circulatory support by the Investigational Device. This device is inserted through a sheath that has been deployed through a femoral puncture, following crimping of the Impella ECP. After proper placement and wireless passage of the aortic valve, the device pumps blood from the left ventricle into the aorta. Once the interventional procedure is completed, the device is weaned and removed. Subjects will be followed up until 30 days post intervention.

The primary and secondary end points will be summarized and presented without formal statistical testing. Safety will be assessed by the rate of composite Major Device-Related Adverse Events, evaluated at the end of the HRPCI procedure. Feasibility is defined as the successful delivery, initiation and maintenance of sufficient hemodynamic support to increase in or maintenance the MAP at physiologic levels (> 60 mmHg), evaluated up to the end of procedure. ;
