A study published on April 9 in Journal of Interventional Cardiology examined complex high-risk patients with multivessel disease who were considered unsuitable for surgery and received an Impella-supported Protected PCI. The study found six months after the Protected PCI, the number of patients with left ventricular ejection fraction (LVEF) greater than or equal to 35% increased by 205%, from 22% to 67% (n=79, p ≤ 0.001).

A study published on April 9 in Journal
of Interventional Cardiology examined complex high-risk patients
with multivessel disease who were considered unsuitable for surgery and
received an Impella-supported Protected PCI. The study found six months
after the Protected PCI, the number of patients with left ventricular
ejection fraction (LVEF) greater than or equal to 35% increased by 205%,
from 22% to 67% (n=79, p ≤ 0.001). The study also found more complete
revascularization was associated with significant LVEF improvement and
During a Protected PCI, the Impella heart pump is implanted minimally
invasively prior to an elective or urgent high-risk percutaneous
coronary intervention (PCI) to support the heart and provide hemodynamic
stability. This technology enables interventional cardiologists to treat
patients with severe coronary artery disease, the majority of whom have
been turned down for open heart surgery.
Impella is the only hemodynamic support device that is FDA PMA approved
as safe and effective for use during high-risk PCI. High-risk PCI is a
first-of-its-kind FDA indication and recognizes an appropriate patient
The original FDA
PMA approval for Impella-supported high-risk PCI in March 2015 was
based on the PROTECT
I FDA Trial and PROTECT
II FDA Randomized Controlled Trial, as well as clinical and
scientific supporting evidence from more than 215 publications, totaling
1,638 Impella patients. Further data was provided from 637 high-risk
patients enrolled in the U.S. Impella registry, now called the cVAD
Study. The submission also incorporated a medical device reporting
analysis from approximately 14,000 Impella patients at the time. In
February 2018, Impella’s
FDA PMA was expanded to include patients with mild or moderately
reduced ejection fraction. The data submitted to the FDA in support of
the expanded PMA indication included an analysis of 230 consecutive
patients with mild to moderately reduced ejection fraction from the cVAD
Abiomed is an industry
leader in tracking real-world evidence and identifying and
validating best practices. Abiomed achieves this insight through FDA
post-approval studies (PAS) embedded in the IRB-approved, prospective
cVAD Study at select hospitals, and by collecting real-world data on
nearly 100% of U.S. Impella patients in the Impella Quality (IQ)
The IQ Database includes data on more than 36,000 Protected PCI patients
who were treated from April 2009 to March 2019. New data, announced
today, shows the mean and median LVEF remains below the ≤35% threshold
that is considered depressed, even after Impella received its expanded

Impella is the only FDA approved therapy for the estimated 121,000 U.S.
high-risk PCI patients3 who qualify each year for the FDA’s
definition of a high-risk PCI. Currently, Abiomed treats approximately
10% of the eligible population. Furthermore, a 2016 study by Doshi, et
al. that published in the Journal
of the American College of Cardiology found, “it can be
estimated that every year more than 325,000 patients with new-onset HF
(heart failure) and CAD (coronary artery disease) might not be
adequately assessed for ischemic CAD4.”
The charts below show patient populations which include patients who are
appropriate for Protected PCI.
Impella enables experienced interventional cardiologists to achieve
complete revascularization and improved patient quality of life as
demonstrated in multiple studies and publications:
of Cardiovascular Medicine, 2008 -Impella patients
studied by Burzotta et al., had an improved LVEF at one year (from 31
± 7% to 41% ± 13%, p=0.02).
of the American College of Cardiology, 2009 - The PROTECT I
trial found patients who had a Protected PCI with Impella had a 31%
improvement in LVEF at 30 day follow up. (from 26 ± 6% to 34 ± 11%, p
2012 -The PROTECT II Randomized Controlled Trial found
Protected PCI with Impella led to a 58% improvement in NYHA class III
and IV heart failure symptoms at 90 days (p<0.001). The trial also
found, during follow-up after Protected PCI with Impella, patients had
a 22% improvement in LVEF (p<0.001).
Cardiovascular Interventions, 2012 – Maini, et al., found a
17% improvement in LVEF at follow up, after a Protected PCI with
Journal of Cardiology, 2014 - An analysis of the PROTECT II
Randomized Controlled Trial by Dangas, et al., found Impella use led
to a 29% reduction in major adverse cardiac and cerebrovascular events
(MACCE) at 90 days, compared to the use of the intra-aortic balloon
pump (IABP) (p=0.042).
of Interventional Cardiology, 2015 - Kovacic, et al., found
Impella maintains patient hemodynamics, allowing for more complete
revascularization and improved outcomes. For example, when three
vessels were treated, the procedural decrease in arterial pressure
from baseline was -18.8% for IABP, compared to -7.6% for Impella
American Journal of Cardiology, 2018 – Alaswad, et al.,
compared patients with LVEF > 35% to patients with LVEF ≤ 35% and
found, despite high-risk features, MACCE rates were favorable, with no
differences between the two groups (3.48% vs 4.54%; p=0.574).
of Interventional Cardiology, 2019 – Burzotta, et al., found
Protected PCI with Impella is associated with LVEF improvement in
complex high-risk patients. The authors also found more complete
revascularization is associated with increased LVEF and survival.
Acute kidney injury (AKI) is lower in Impella patients undergoing
2012 -The PROTECT II Randomized Controlled Trial found,
despite higher levels of contrast in the Impella arm, acute renal
dysfunction was lower in the Impella arm at 30 days and 90 days
(p=0.792 and p=0.776, respectively).
Research, 2017 - Flaherty, et al., identified a six-fold
reduction in AKI requiring dialysis when Impella support was used,
compared to without Impella support (p=0.031).
of the American College of Cardiology, 2019 – Flaherty et al.,
found, compared to a predicted rate of 22%, only 7% of
Impella-supported patients developed AKI at 72 hours, representing a
70% lower AKI risk (p<0.0001).
Impella is cost effective:
Drug & Health Benefits, 2013 - Gregory, et al., found
Impella had a 52% reduction in readmissions from repeat
revascularization (p=0.024) and a 22% reduction in length of stay
(p=0.008), compared to IABP use.
of the American College of Cardiology, 2014 – Stretch, et al.,
found in cases of cardiogenic shock in coronary atherosclerosis and
other heart disease, percutaneous ventricular assist devices (pVADs)
reduced costs by $54,000 per case (p=0.015) and reduced mortality by
Review of Pharmacoeconomics & Outcomes Research, 2014 – An
evaluation of six studies of the economic impact and relative value of
pVADs finds they are cost effective in the long-term.
Patients who have benefited from Protected PCI with Impella include Mongin
Smyly, whose constant fatigue and weakness left him feeling
hopeless. That’s when he was identified as an appropriate candidate for
a Protected PCI with Impella. Following his procedure, Mr. Smyly
experienced an improved quality of life and was able to return to work.
He said, “Following the Protected PCI procedure, I felt better than I
had in a long time. Today, I am back to enjoying life with my wife and
family and I am beyond grateful.”
"The scientific evidence clearly demonstrates the advantages of
conducting a Protected PCI in patients who have compromised
hemodynamics, complex coronary artery disease and comorbidities. In the
past, these patients would have had minimal to no other treatment
options,” said Ayaz Rahman, MD, the interventional cardiologist at
Parkwest Medical Center who treated Mr. Smyly. “Protected PCI with
Impella allows for more complete revascularization and better long-term
outcomes. It also improves the patient’s quality of life and reduces

1Patients with ejection fraction values
February 14, 2018, Impella’s FDA PMA indication was expanded to read:
The Impella 2.5®, Impella CP® and Impella CP®
with SmartAssist® Systems are temporary (≤ 6 hours)
ventricular support devices indicated for use during high-risk
percutaneous coronary interventions (PCI) performed in elective or
urgent, hemodynamically stable patients with severe coronary artery
disease, when a heart team, including a cardiac surgeon, has determined
high-risk PCI is the appropriate therapeutic option. Use of the Impella
2.5, Impella CP, and Impella CP with SmartAssist Systems in these
patients may prevent hemodynamic instability, which can result from
repeat episodes of reversible myocardial ischemia that occur during
planned temporary coronary occlusions and may reduce peri- and
post-procedural adverse events.
