First U.S. Patients Treated with Impella 5.5 with SmartAssist


Three cardiac surgeons at Cleveland Clinic, Hackensack Meridian Health and Cedars-Sinai Medical Center are the first in the United States to implant Abiomed’s (NASDAQ: ABMD) newest heart pump, the Impella 5.5 with SmartAssist. Ed Soltesz, MD, Mark Anderson, MD, and Danny Ramzy, MD, have each successfully implanted multiple pumps during cardiac procedures at their hospitals.

Dr. Mark Anderson

Mark Anderson, MD, chief of the Division of Cardiac Surgery and cardiothoracic surgeon at the Heart and Vascular Hospital at Hackensack University Medical Center and Hackensack Meridian Health said, “The Impella 5.5 is a promising new option for heart failure patients in cardiogenic shock. It is easy to implant through the axillary artery to avoid opening the chest or, if the chest is already open during a surgical procedure, it can be implanted directly into the anterior aorta. Additionally, with SmartAssist, I can monitor the left ventricle function of my patient in real time in the ICU.”

The Impella 5.5 with SmartAssist has received the U.S. Food and Drug Administration’s (FDA) highest level of approval for safety and efficacy in the therapy of cardiogenic shock for up to 14 days. It is a temporary heart pump that is:

  • Minimally invasive, eliminating the need for a sternotomy or coring of the left ventricle
  • Designed for heart surgeons, implanted via the axillary artery or the anterior aorta
  • Forward flow, to provide the patient with coronary flow and end organ perfusion
  • Fully unloading, to reduce the heart’s oxygen demand and work
  • Equipped with SmartAssist, designed to provide weaning algorithms to optimize survival and native heart recovery

Impella 5.5 with SmartAssist delivers peak flows of greater than 6 liters per minute. A motor housing that is thinner and 45% shorter than the Impella 5.0 improves ease of pump insertion through the vasculature.

“The Impella 5.5 with SmartAssist is an innovative pump designed for heart surgeons to treat heart failure patients in cardiogenic shock and optimize heart recovery with SmartAssist real-time feedback in the ICU and on surgeons’ smart phones with Impella Connect,” said Michael R. Minogue, Chairman, President and Chief Executive Officer of Abiomed.

The Impella 5.5 with SmartAssist is being introduced in the United States through a controlled rollout at hospitals with established heart recovery protocols. It received CE marking approval in Europe in April 2018 and was introduced in Germany through a similar controlled rollout.

ABOUT IMPELLA HEART PUMPS: The Impella 2.5® and Impella CP® devices are U.S. FDA PMA approved to treat certain advanced heart failure patients undergoing elective and urgent percutaneous coronary interventions (PCI) such as stenting or balloon angioplasty, to re-open blocked coronary arteries. The Impella 2.5, Impella CP, Impella CP with SmartAssist®, Impella 5.0®, Impella LD®, and Impella 5.5™ with Smart Assist® are U.S. FDA approved heart pumps used to treat heart attack or cardiomyopathy patients in cardiogenic shock, and have the unique ability to enable native heart recovery, allowing patients to return home with their own heart. The Impella RP® is U.S. FDA approved to treat right heart failure or decompensation following left ventricular assist device implantation, myocardial infarction, heart transplant, or open-heart surgery. Impella is the most studied mechanical circulatory support device in the history of the FDA with real world clinical data on more than 100,000 patients and more than 550 peer-reviewed publications.
