Use of the Impella BTR™ in Patients With Heart Failure: An Early Feasibility Study (BTR EFS)

Intervention / Treatment
Detailed Description
The objectives of this Early Feasibility Study are to evaluate the safety of the Impella BTR™ in adult patients requiring left-ventricular hemodynamic support. Additionally, to evaluate the feasibility of the Impella BTR™ in supporting patients to recovery or their next therapy. The investigational device consists of the following primary device and accessories: The Impella BTR™ Pump System (an intravascular transvalvular, micro-axial blood pump) and the Modified Automated Impella Controller™ (AIC) to allow control of the Impella BTR.
Following informed consent, subjects that meet all of the inclusion and none of the exclusion criteria, and in whom the Impella BTR™ is implanted or attempted to be implanted, will be considered enrolled into the Study. The device is inserted during a surgical procedure through a vascular graft that has been sutured onto the left or right axillary artery. After proper placement and passage through the aortic valve with the help of a guidewire, the device pumps blood from the left ventricle into the aorta. Once hemodynamic support is no longer required, the device is weaned and removed. Subjects will be followed to 90 days post-implant.
The primary and secondary endpoints will be summarized and presented without formal statistical testing. All adverse events including all Protocol-defined events, serious and non-serious, will be documented and reported from the time of subject enrollment until Study completion. Feasibility is defined as the ability of the pump to provide clinically adequate support for the duration of the implant up to 28 days. Clinically adequate support is defined as operating without device malfunctions or failures that result in device removal, replacement or use of an additional MCS device.

- Subject has signed the Informed Consent
- Subject has pre-existing heart failure, with NYHA Class IV prior to the index admission
Subject is presenting with acute heart failure and meets one of the following criteria:
- Sustained episode of systolic blood pressure ≤90 mmHg for at least 30 minutes or need for vasoactive agents to maintain such blood pressure
- Or a cardiac index (CI) <2.2 L/min/m2 determined to be secondary to cardiac dysfunction, in the absence of hypovolemia

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Subjects receiving the Impella BTR
|
Subjects will be prepared for pump insertion procedure according to clinical site standard of care.
Procedural preparations for insertion of the Impella BTR are identical to the insertion of the Impella 5.0/5.5 via the axillary artery.
The Impella BTR remains in situ until the patient is sufficiently recovered for removal or is transitioned to another form of support.
It is expected that the Impella BTR is in situ for a maximum of 28 days.
