Study Finds 84% Survival Rate in Patients in Cardiogenic Shock and Other Challenging Cardiac Conditions with the New Impella 5.5 with SmartAssist
The first published United States experience of patients who received Abiomed’s newest heart pump, Impella 5.5 with SmartAssist, finds 84% of the patients survived to explant with 76% native heart recovery. The study was published in the July edition of the American Society for Artificial Internal Organs (ASAIO) Journal.

The study examined the outcomes of the first 55 patients treated with Impella 5.5 with SmartAssist at Cleveland Clinic, Hackensack University Medical Center/Hackensack Meridian Health and Cedars-Sinai Medical Center. Study authors and cardiac surgeons Ed Soltesz, MD, Mark Anderson, MD, and Danny Ramzy, MD, conclude Impella 5.5 with SmartAssist is safe and effective for a number of challenging clinical scenarios, including AMI cardiogenic shock.
“This report demonstrates the benefit of unloading cardiogenic shock patients and it is encouraging to see real-world data demonstrate improved survival rates with use of Impella 5.5 with SmartAssist,” said Danny Ramzy, MD, assistant professor, surgical director of the lung transplant program, and director, robotic and minimally invasive cardiac surgery at Cedars-Sinai Medical Center. “The continued use of best practices, techniques and innovative technology like Impella allows us to provide better patient care that improves outcomes and quality of life.”
In September 2019, Impella 5.5 with SmartAssist received FDA pre-market approval (PMA) for safety and efficacy in the therapy of cardiogenic shock for up to 14 days. It is a micro-axial, surgically implanted, temporary heart pump that unloads the left ventricle, reduces ventricular work, and provides the circulatory support necessary to allow native heart recovery and early assessment of residual myocardial function. Its benefits include:
- Ease of insertion through the axillary artery or the anterior aorta
- Designed for long-duration support with durable ceramic bearings, no pigtail to minimize adhesions, and ability for patient ambulation
- Forward flow with maximum unloading, to provide end organ and coronary perfusion, while allowing the heart to rest
- Better patient management with intelligent device positioning, management, and weaning with SmartAssist technology
- Equipped with Impella Connect, a cloud-based monitoring and collaborative patient management platform that allows for remote monitoring of the Impella console. During the COVID-19 crisis, this online, HIPAA-compliant monitoring service is being provided at no cost to help medical providers manage patients 24/7.
The 55 patients in the study were implanted with Impella 5.5 with SmartAssist between October 16, 2019 and March 4, 2020. Specifically, the study authors determined:
- 35 patients (63.6%) were successfully weaned off the technology.
- 11 patients (20.0%) went on to receive another therapy, two patients (3.6%) expired while on support, and seven patients (12.7%) had care withdrawn.
- 76.1% of survivors recovered native heart function.
- There were no device-related strokes, hemolysis, or limb ischemia observed.
- The results demonstrate Impella provides dependable acute mechanical circulatory support for patients who need it by stabilizing their hemodynamics during treatment.

ViiV Healthcare Announces US FDA Approval for Rukobia (fostemsavir), a First-in-Class Treatment for HIV in Adults With Few Treatment Options Available2.7.2020 22:39:00 CEST | Press release
ViiV Healthcare, the global specialist HIV company majority owned by GSK, with Pfizer Inc. and Shionogi Limited as shareholders, today announced that the US Food and Drug Administration (FDA) has approved Rukobia (fostemsavir), 600 mg extended-release tablets. Rukobia is a novel attachment inhibitor for the treatment of HIV-1 infection indicated for use in combination with other antiretroviral (ARV) therapies in heavily treatment-experienced (HTE) adults with multidrug-resistant HIV-1 infection, who are failing their current ARV regimen due to resistance, intolerance or safety considerations. Significant advances over the past few decades have dramatically improved HIV treatment and for many, HIV is considered a manageable life-long condition. However, HTE adults – which account for approximately 6% of adults living with HIV who are on treatment – have little to no options left due to resistance, tolerability or safety considerations.1 HTE adults are at risk of progressing to AIDS and
