简要总结
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 or urgent high-risk percutaneous coronary intervention.
详细描述
This is a prospective, multicenter, single-arm, feasibility study evaluating the safety of the Impella ECP device in adult patients undergoing an elective or urgent 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.

入排标准
入选标准
- •Age ≥ 18 years and ≤ 90 years
- •Subject has signed the informed consent
- •Scheduled for an elective or urgent high risk percutaneous coronary intervention with hemodynamic support
排除标准
- •Aortic valve disease that is anticipated to be prohibitive to Impella ECP crossing, including greater than mild aortic stenosis
- •Previous aortic valve replacement or reconstruction
- •Thrombus in left ventricle
- •Subjects with known aortic vessel disease or with aortic dissection
- •Any contraindication that precludes placing an Impella including aortic, iliac or femoral disease such as tortuosity, extensive atherosclerotic disease or stenosis
- •Prior stroke with any permanent neurologic deficit or any prior intracranial hemorrhage or any prior subdural hematoma or known intracranial pathology pre-disposing to intracranial bleeding, such as an arteriovenous malformation or mass
- •Cardiogenic shock or acutely decompensated pre-existing chronic heart failure. Cardiogenic shock is defined as: systemic hypotension (systolic BP \<90 mmHg or the need for inotropes/pressors to maintain a systolic BP \>90 mmHg) plus one of the following: any requirement for pressors/inotropes prior to arrival at the catheterization laboratory, clinical evidence of end-organ hypoperfusion or use of IABP or any other circulatory support device
- •Infection of the proposed procedural access site or suspected systemic active infection, including any fever
- •Subject has previously been symptomatic with or hospitalized for COVID-19 unless he/she has been discharged (if hospitalized) and asymptomatic for ≥8 weeks and has returned to his/her prior baseline (pre-COVID) clinical condition
- •Known contraindication to heparin (i.e., heparin-induced thrombocytopenia), contrast media or Study-required medication(s) (i.e., aspirin)
