2.0 Indications
The Edwards SAPIEN XT transcatheter heart valve, model 9300TFX, and accessories are indicated for
relief of aortic stenosis in patients with symptomatic heart disease due to severe native calcific aortic
stenosis who are judged by a Heart Team, including a cardiac surgeon, to be at intermediate or greater
risk for open surgical therapy
(i.e., predicted risk of surgical mortality ≥ 3% at 30 days, based on the
Society of Thoracic Surgeons (STS) risk score and other clinical co-morbidities unmeasured by the STS
risk calculator).
The Edwards SAPIEN XT transcatheter heart valve and accessories are also indicated for patients with
symptomatic heart disease due to failure (stenosed, insufficient, or combined) of a surgical bioprosthetic
aortic valve who are judged by a heart team, including a cardiac surgeon, to be at high or greater risk for
open surgical therapy (i.e., STS operative risk score ≥8% or at a ≥15% risk of mortality at 30 days).
3.0 Contraindications
The valve and delivery systems are contraindicated in patients who cannot tolerate an
anticoagulation/antiplatelet regimen or who have active bacterial endocarditis or other active infections.
4.0 Warnings
•
Observation of the pacing lead throughout the procedure is essential to avoid the potential risk of
pacing lead perforation.
•
There may be an increased risk of stroke in transcatheter aortic valve replacement procedures, as
compared to balloon aortic valvuloplasty or other standard treatments in high or greater risk patients.
•
The devices are designed, intended, and distributed for single use only.
Do not resterilize or reuse
the devices.
There are no data to support the sterility, nonpyrogenicity, and functionality of the
devices after reprocessing.
•
Care should be exercised when sizing the native annulus or surgical valve; implanting a valve that is
too small may lead to paravalvular leak, migration or embolization, whereas implanting a valve that is
too large may lead to residual gradient (patient-prosthesis mismatch) or annular rupture.
•
Accelerated deterioration of the valve may occur in patients with an altered calcium metabolism.
•
Prior to delivery, the valve must remain hydrated at all times and cannot be exposed to solutions
other than its shipping storage solution and sterile physiologic rinsing solution. Valve leaflets
mishandled or damaged during any part of the procedure will require replacement of the valve.
•
Caution should be exercised in implanting a valve in patients with clinically significant coronary artery
disease.
•
Patients with pre-existing mitral valve devices should be carefully assessed prior to implantation of
the valve to ensure proper valve positioning and deployment.
•
Do not use the valve if the tamper evident seal is broken, the storage solution does not completely
cover the valve, the temperature indicator has been activated, the valve is damaged, or the
expiration date has elapsed.
•
Do not mishandle the N delivery system or use it if the packaging or any components are
not sterile, have been opened or are damaged (e.g. kinked or stretched), or the expiration date has
elapsed.
•
Use of excessive contrast media may lead to renal failure. Measure the patient’s creatinine level
prior to the procedure. Contrast media usage should be monitored.
•
Patient injury could occur if the delivery system is not un-flexed prior to removal.
•
Care should be exercised in patients with hypersensitivities to cobalt, nickel, chromium,
molybdenum, titanium, manganese, silicon, and/or polymeric materials.
•
The procedure should be conducted under fluoroscopic guidance. Some fluoroscopically guided
procedures are associated with a risk of radiation injury to the skin. These injuries may be painful,
disfiguring, and long-lasting.
•
Valve recipients should be maintained on anticoagulant/antiplatelet therapy, except when
