2.0 Indications
The Edwards SAPIEN 3 transcatheter heart valve, Model 9600TFX, 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).
3.0 Contraindications
The valve and delivery systems are contraindicated in patients who cannot tolerate an anticoagulation/anti pla tel et r egim en 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 ma y 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.
Incorrect sizing of the valve may lead to paravalvular leak, migration, embolization and/or annul ar 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
3
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 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 contraindicated, as determined by their physician. This device has not been tested for use without anticoagulation.
Do not add or apply antibiotics to the storage solution, rinse solutions, or to the valve.
5.0 Precautions
Long-term durability has not been established for the valve. Regular medical follow-up is advised to evaluate valve performance.
Glutaraldehyde may cause irritation of the skin, eyes, nose and throat. Avoid prolonged or repeated exposure to, or breathing of, the solution. Use only with adequate ventilation. If skin contact occurs, immediately flush the affected area with water; in the event of contact with eyes, seek immediate medical attention. For more information about glutaraldehyde exposure, refer to the Mater ia l Safet y Data Sheet available from Edwards Lifesciences.
To maintain proper valve leaflet coaptation, do not overinflate the deployment balloon.
Appropriate antibiotic prophylaxis is recommended post-procedure in patients at risk for prosthetic
valve infection and endocar ditis .

Step Procedure
1
2
Set up two (2) sterile bowls with at least 500 mL of sterile physiological saline to thoroughly rinse the glutaraldehyde sterilant from the valve.
Carefully remove the valve/holder assembly from the jar without touching the tissue. Verify the valve serial identification number with the number on the jar lid and record in the patient information documents. Inspect the valve for any signs of damage to the frame or tissue.
Rinse the valve as follows: Place the valve in the first bowl of sterile, physiological saline. Be sure the saline solution completely covers the valve and holder. With the valve and holder submerged, slowly agitate (to gently swirl the valve and holder) back and forth for a minimum of 1 minute. Transfer the valve and holder to the second rinsing bowl of sterile physiological sal ine and g ently agitate for at least one more minute. Ensure the rinse solution in the first bowl is not used. The
3
valve should be left in the final rinse solution until needed to prevent the tissue from drying.
CAUTION: Do not allow the valve to come into contact with the bottom or sides of the rinse bowl during agitation or swirling in the rinse solution. Direct contact between the identification tag and valve is also to be avoided during the rinse procedure. No other objects should be placed in the rinse bowls. The valve should be kept hydrated to prevent the tissue from drying.
7.2.2 Prepare the Com p o n ents
Refer to the Edwards eSheath Introducer Set, Edwards Crimper and Edwards Balloon Catheter instructions for use for device preparation.
Step Procedure
Visually inspect all components for damage. Ensure the Edwards Commander delivery system is fully unflexed and the balloon catheter is fully advanced in the flex catheter.

lumen with heparinized saline and insert the stylet back into the distal end of the guidewire lumen. Note: Failure to insert the stylet back into the guidewire lumen may result in damage to the lumen
during crimping process. Place the delivery system into the default position and make sure that the flex catheter tip is covered
by the proximal balloon cover. Unscrew the loader cap from the loader tube and flush the lo ader cap. Place the loader cap over the proximal balloon cover and onto the flex catheter with the inside of the cap oriented towards the distal tip.
Fully advance the balloon catheter in the flex catheter. Peel off the proximal balloon cover over the blue section of the balloon shaft.
Attach a 3-way stopcock to the balloon inflation port. Partially fill a 50 cc or larger syringe with 15-20 mL diluted contrast medium and attach to the 3-way stopcock.
Fill the inflation device provided by Edwards Lifesciences with excess volume relative to the indicated inflation volume. Lock the inflation device and attach to the 3-way stopcock.
Close the 3-way stopcock to the Inflation device provided by Edwards Lifesciences and de-air the system using the 50 cc or larger syringe. Slowly release the plunger and leave zero-pressure in the system.
Close the stopcock to the delivery system. By rotating the knob of the inflation device provided by Edwards Lifesciences, transfer the contrast medium into the syringe to achieve the appropriate volume required to deploy the valve.

Set up two (2) additional sterile bowls with at least 100 mL of sterile physiological saline to thoroughly rinse the Qualcrimp crimping accessory.
Completely submerge the Qualcrimp crimping accessory in the first bowl and gently compress it to ensure complete saline absorption. Slowly swirl the Qualcrimp crimping accessory for a minimum of 1 minute. Repeat this process in the second bowl.
With the crimper in the open position, gently place the valve into the crimper aperture. Gradually crimp the valve until it fits into the Qualcrimp crimping accessory.
Place the Qualcrimp crimping accessory over the valve making sure the valve is parallel to the edge of the Qualcrimp crimping accessory.
Place the valve and Qualcrimp crimping accessory in crimper aperture. Insert the delivery system coaxially within the valve on the Valve Crimp Section (2-3 mm distal to the balloon shaft) with the inflow (outer skirt) end of th e valve towards the distal end of the delivery system.
Gently remove the Qualcrimp crimping accessory from the valve. Remove the Qualcrimp Stop from the Final Stop, leaving the Final Stop in place.
Fully crimp the valve until it reaches the Final Stop.
NOTE: Ensure that the Valve Crimp Section remains coaxial within the valve.
11 Repeat the full crimp of the valve two more times for a total of three full crimps. 12 Pull the balloon shaft and lock in the default position.
Flush the loader with heparinized saline. Immediately advance the valve into the loader until the
13
14
tapered tip of the delivery system is exposed.
CAUTION: To prevent possible leaflet damage, the valve should not remain fully crimped and/or in the loader for over 15 minutes.
Attach the loader cap to the loader, re-flush the delivery system through the flush port and close the stopcock to the delivery system.
Remove the stylet and flush the guidewire lumen of the delivery system.
CAUTION: Keep the valve hydrated until ready for implantation. CAUTION: The physician must verify correct orientation of the valve prior to its implantation;
its inflow (outer skirt) end should be oriented distally towards the tapered tip.
7.3 Valvuloplasty and Valve Delivery
Valvuloplasty and valve delivery should be performed under conscious sedation and/or general anesthesia with hemodynamic monitoring in a catheterization lab/hybrid operating room with fluoroscopic and echocardiographic imaging capabilities.
Administer heparin to maintain the ACT at ≥ 250 sec during the procedure.
CAUTION: 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.
CAUTION: Procedure may require an arterial cut-down with surgical closure of the puncture si te due to the size of the arteriotomy.

8.0 How Supplied
STERILE: The valve is supplied sterilized with glutaraldehyde solution. The delivery system is supplied sterilized with ethylene oxide gas.
8.1 Storage
The valve must be stored at 10 °C to 25 °C (50 °F to 77 °F). Each jar is shipped in an enclosure containing a temperature indicator to detect exposure of the valve to extreme temperature.
The delivery system should be stored in a cool, dry place.
9.0 MR Safety
MR Conditional
Non-clinical testing has demonstrated that the Edwards SAPIEN 3 transcatheter heart valve is MR Conditional. A patient with this device can be scanned safely, immediately after placement of this device under the following conditions:
Static magnetic field of 1.5 tesla or 3 tesla
Maximum spatial gradient field of 2500 gauss/cm (25 T/m) or less
Maximum MR system reported, whole body averaged specific absorption rate (SAR) of 2 W/kg
(Normal Operating Mode)
Under the scan conditions defined above, the SAPIEN 3 transcatheter heart valve is expected to produce a maximum temperature rise of 3.0 ºC after 15 minutes of continuous scanning.
11
In non-clinical testing, the image artifact caused by the device extends as far as 14.5 mm from the implant for spin echo images and 30 mm for gradient echo images when scanned in a 3.0T MRI system. The artifact obscures the device lumen in gradient echo images.
The implant has not been evaluated in MR systems other than 1.5 or 3.0T.
10.0 Patient Information
Patient education brochures are provided to each site and should be given to the patient to inform them of the risks and benefits of the procedure and alternatives in adequate time before the procedure to be read and discussed with their physician. A copy of this brochure may also be obtained from Edwards Lifesciences by calling 1.800.822.9837. A patient implant card request form is provided with each transcatheter heart valve. After implantation, all requested information should be completed on this form. The serial number may be found on the package and on the identification tag att ached to the t ranscathete r heart valve. The original form should be returned to the Edwards Lifesciences address indicated on the form and upon receipt, Edwards Lifesciences will provide an identification card to the patient.
11.0 Recovered Valve and Device Disposal
The explanted valve should be placed into a suitable histological fixative such as 10% formalin or 2% glutaraldehyde and returned to the company. Refrigeration is not necessary under these circumstances. Contact Edwards Lifesciences to request an Explant Kit.
Used delivery system may be disposed of in the same manner that hospital waste and biohazard ous materials are handled. There are no special risks related to the disposal of these devices.
12.0 Clinical Studies
SUMMARY OF PRIMARY CLINICAL STUDY The PARTNER II Trial Overview, SAPIEN 3 Valve
SAPIEN 3 High Risk and Inoperable Cohort: The SAPIEN 3 High Risk and Inoperable Cohort of the PARTNER II trial (PIIS3HR) was a single arm, non-randomized, historical-controlled study to compare the third generation Edwards SAPIEN 3 valve system with the first generation Edwards SAPIEN valve system in patients who either have high risk for surgery or cannot undergo surgery (inoperable). The valve sizes used in the PIIS3HR trial included only the 23, 26 and 29 mm sizes. The 20 mm valve size was introduced into the trial after enrollment was completed with the three larger sizes, thus a separate nested registry, NR7, with identical inclusion/exclusion criteria as the PIIS3HR Cohort except for the aortic annulus diameter, was created to collect data for the 20 mm valve. Data from the PIIS3HR cohort and NR7 are pooled for the statistical analyses. For convenience, this combined cohort is referred to as “PIIS3HR” hereafter.
The database included 583 eligible patients enrolled at 29 investigational sites in the U.S. The study used an independent Data Safety Monitoring Board (DSMB) that was instructed to notify
Edwards Lifesciences of any safety or compliance issues, a Clinical Events Committee (CEC) that was responsible for adjudicating endpoint related events reported during the trial per a priori established VARC 2 definitions
[1]
, an ECG core laboratory for independent analysis of rhythm, and an
echocardiographic core laboratory for independently analyzing all echocardiograms. SAPIEN 3 Intermediate Risk Cohort: The PIIS3i Cohort of the PARTNER II trial was a single arm, non-
randomized, historical-controlled study to compare TAVR with the Edwards SAPIEN 3 valve system to the surgical aortic valve replacement (SAVR) arm from the previous PARTNER II trial Cohort A (PIIA-SAVR) in patients who were judged by a heart team to be at intermediate risk for open surgical therapy. The valve sizes used in the PIIS3i study included the 20, 23, 26, and 29 mm sizes.
Patients in PIIS3i were treated between February 2014 and September 2014. Patients in PIIA-SAVR were treated between January 2012 and November 2013. The database reflected data collected through December 10, 2015 and included 1,078 patients in PIIS3i enrolled at 51 investigational sites in the U.S and 1,021 patients in PIIA-SAVR enrolled at 57 investigational sites in the U.S.

Safety and Effectiveness Results
Primary Endpoint The composite rate of all-cause mortality, all stroke, and AI ≥ moderate at 30 days was 6.7% in the
SAPIEN 3 cohort and 15.6% in the SAPIEN cohort, as shown in Table 7. The resulting proportion difference in the average treatment effect on the treated (ATT; [2]) was -6.9% (90% CI: [-13.3%, -0.5%]). Since the upper limit of the CI was < 7.5%, the non–inferiority was met.
