THE BEST STENT WE'VE EVER MADE

With XIENCE Sierra, Abbott’s life-changing heart stent offers cardiologists a new level of care and precision.

The Best Stent We've Ever Made

Aug 24 2018

Percutaneous coronary intervention, or PCI, is a minimally-invasive heart procedure.

In the simplest, here’s how it works:

  • An interventional cardiologist inserts a catheter through the leg or arm and guides it to the blockage near the heart, which is revealed through a contrasting dye. There's no need to open the chest.
  • Once there, the surgeon maneuvers a guide wire and tiny balloon through the blockage, where the balloon is inflated to open a clear path for blood to resume its flow.
  • A stent — a tiny, wire mesh tube — is inserted to keep the opening from collapsing, ensuring continued flow after the catheter and balloon are removed.

For the metal stent, it's a one-way journey.

Once in place, a stent is intended for long-term protection.

Complex PCI is what you would guess from its name: A high-degree of difficulty where a person has heavy hardening of the arteries (considered “calcified”), long or multiple blockages (also known as "lesions") or the need for multiple stents. More than 70 percent of cases fit some or all of this description.1

About those multiple stents that are there for the long term?

With a highly specialized coating that lowers the likelihood of the artery becoming re-blocked, our XIENCE stents have an unparalleled safety record2 from more than 100 clinical trials3 and 10 years of real-world experience. They're helping more than 8 million people worldwide live their best lives.4

And now, with XIENCE Sierra, our life-changing heart stent has taken another step forward. Thanks to Food and Drug Administration approval, this stent is now available to people suffering from complex cases of blocked arteries in the U.S. For interventional cardiologists and the people under their care, XIENCE Sierra brings unparalleled safety to even the most complex cases.

"We developed XIENCE Sierra so that physicians can more easily deliver the stent even in challenging cases," said Chuck Brynelsen, senior vice president of Abbott's vascular business. "The updated design and improved deliverability mean doctors can access and unblock difficult-to-treat lesions with more flexibility and precision while having confidence in the outcomes and safety they expect from XIENCE."

XIENCE Sierra was approved in Europe in 2017 and recently received regulatory approval and reimbursement in Japan.

Javier Escaned, head of the International Cardiology Section at Hospital Clinico in San Carlos, Madrid, has first-hand experience with XIENCE Sierra.

"It was a reliable stent because it allowed me to perform a tough technique with a lot of ease," Dr. Escaned said. It was a stent that was able to face the challenges of having brisk changes in vessel diameter. It’s a very reassuring stent in the sense that we know that the long-term results with XIENCE are very good." very reassuring stent in the sense that we know that the long-term results with XIENCE are very good."

"With its unparalleled and well-known safety record, XIENCE Sierra is a critical part of our strategy to combat coronary artery disease," Brynelsen said. "But our strategy is not just a new stent. It's ensuring we provide technologies that help doctors optimally implant stents to give patients the best chances for good outcomes. Our diagnostic and imaging tools provide everything an interventional cardiologist needs to treat complex PCI."

IMPORTANT SAFETY INFORMATION

Caution: This product is intended for use by or under the direction of a physician. Prior to use, reference the Instructions for Use provided inside the product carton (when available), at eifu.abbottvascular.com or at medical.abbott/manuals for more detailed information on Indications, Contraindications, Warnings, Precautions and Adverse Events.

The XIENCE V®, XIENCE nano®, XIENCE PRIME®, XIENCE PRIME® LL, XIENCE Xpedition®, XIENCE Xpedition® SV and XIENCE Xpedition® LL, XIENCE Alpine®, and XIENCE SierraTM (XIENCE Family) of Everolimus Eluting Coronary Stents on the MULTILINK VISION® or MULTI-LINK MINI VISION® Delivery System

INDICATIONS
The XIENCE Sierra stent system is indicated for improving coronary artery luminal diameter in patients, including those with diabetes mellitus, with symptomatic heart disease due to de novo native coronary artery lesions (length £ 32 mm) with reference vessel diameters of ≥ 2.25 mm to ≤ 4.25 mm. In addition, the XIENCE Sierra stent system is indicated for treating de novo chronic total coronary occlusions.

CONTRAINDICATIONS
The XIENCE Sierra stent system is contraindicated for use in:

  • Patients who cannot tolerate, including allergy or hypersensitivity to, procedural anticoagulation or the post-procedural antiplatelet regimen.
  • Patients with hypersensitivity or contraindication to everolimus or structurally related compounds, or known hypersensitivity to stent components (cobalt, chromium, nickel, tungsten, acrylic, fluoropolymers), or with contrast sensitivity.

WARNINGS

  • It is not recommended to treat patients having a lesion that prevent complete inflation of an angioplasty balloon.
  • Judicious patient selection is necessary because the use of this device carries the associated risk of stent thrombosis, vascular complications, and/or bleeding events.
  • This product should not be used in patients who are not likely to comply with the recommended antiplatelet therapy.

PRECAUTIONS

  • Ensure that the inner package sterile barrier has not been opened or damaged prior to use.
  • Stent implantation should only be performed by physicians who have received appropriate training.
  • Stent placement should be performed at hospitals where emergency coronary artery bypass graft surgery (CABG) is accessible.
  • Subsequent restenosis may require repeat dilatation of the arterial segment containing the stent. Long-term outcomes following repeat dilatation of the stent are presently unknown.
  • Care should be taken to control the guiding catheter tip during stent delivery, deployment and balloon withdrawal. Before withdrawing the stent delivery system, visually confirm complete balloon deflation by fluoroscopy to avoid guiding catheter movement into the vessel and subsequent arterial damage.
  • When DES are used outside the specified Indications for Use, patient outcomes may differ from the results observed in the SPIRIT family of trials.
  • Compared to use within the specified Indications for Use, the use of DES in patients and lesions outside of the labeled indications may have an increased risk of adverse events, including stent thrombosis, stent embolization, MI, or death.
  • Orally administered everolimus combined with cyclosporine is associated with increased serum cholesterol and triglycerides levels.
  • A patient's exposure to drug and polymer is proportional to the number and total length of implanted stents. See Instructions for Use for current data on multiple stent implantation.
  • Safety and effectiveness of the XIENCE Family of stents have not been established for subject populations with the following clinical settings:

Patients with prior brachytherapy of the target lesion or the use of brachytherapy for treated site restenosis, patients in whom mechanical atherectomy devices or laser angioplasty catheters are used in conjunction with XIENCE Family stents, women who are pregnant or lactating, men intending to father children, pediatric patients, unresolved vessel thrombus at the lesion site, coronary artery reference vessel diameters < 2.25 mm or > 4.25 mm or lesion length > 32 mm, lesions located in saphenous vein grafts, unprotected left main coronary artery, ostial lesions, lesions located at a bifurcation or previously stented lesions, diffuse disease or poor flow (TIMI < 1) distal to the identified lesions, excessive tortuosity proximal to or within the lesion, recent Acute Myocardial Infarction (AMI) or evidence of thrombus in target vessel, multivessel disease, and in-stent restenosis.

  • Everolimus has been shown to reduce the clearance of some prescription medications when administered orally along with cyclosporine (CsA). Formal drug interaction studies have not been performed with the XIENCE Family of stents because of limited systemic exposure to everolimus eluted from the stent.
  • Everolimus is an immunosuppressive agent. Consideration should be given to patients taking other immunosuppressive agents or who are at risk for immune suppression.
  • Oral everolimus use in renal transplant patients and advanced renal cell carcinoma patients was associated with increased serum cholesterol and triglycerides, which in some cases required treatment.
  • Non-clinical testing has demonstrated that the XIENCE Sierra stent, in single and in overlapped configurations up to 71 mm in length, is MR Conditional. It can be scanned safely under the conditions in the Instructions for Use.
  • The XIENCE Family of stents should be handled, placed, implanted, and removed according to the Instructions for Use.
