Temporary right ventricular support with Impella Recover RD axial flow pump

Area of Science:

• Cardiology
• Medical Devices
• Cardiovascular Surgery

Background:

• Post-cardiotomy right ventricular failure is a significant complication with poor outcomes.
• Temporary mechanical circulatory support is crucial for managing this condition.
• The Impella Recover RD is a percutaneous ventricular assist device.

Purpose of the Study:

• To evaluate the safety and efficacy of the Impella Recover RD for temporary right ventricular support.
• To assess the outcomes of patients receiving the Impella Recover RD after cardiac surgery.
• To report preliminary clinical experience with this device.

Main Methods:

• Retrospective review of 7 patients receiving the Impella Recover RD from January 2007 to December 2007.
• Device implantation for temporary support after heart transplantation, mitral valve replacement, or with a left ventricular assist device.
• Analysis of hemodynamic parameters, duration of support, and patient outcomes.

Main Results:

• Effective hemodynamic support was achieved in all patients, with significant reduction in central venous pressure.
• Mean duration of support was 4.9 days; 3 patients were successfully weaned and explanted.
• Complications included pump dysfunction in 2 patients and mortality due to recurrent failure or sepsis.

Conclusions:

• The Impella Recover RD demonstrates effectiveness in providing temporary right ventricular support.
• The device is easily implanted and explanted, often without cardiopulmonary bypass.
• Improvements in mechanical reliability are necessary for wider clinical adoption.
