    PATIENT COUNSELING INFORMATION

    Physicians should review the following information when counseling patients about the AmplatzerTM TalismanTM PFO Occluder and the implant procedure:

    • The safety and effectiveness of PFO closure withthe AmplatzerTM TalismanTM PFO Occluder in combination with the required post- implant antiplatelet therapy.
    • PFO closure with the AmplatzerTM TalismanTM PFO Occluder can only reduce the risk for a recurrent stroke due to a paradoxical embolism through a PFO.
      • With aging, there is an increased likelihood that non-PFO related risks for stroke may develop and cause a recurrent ischemic stroke independent of PFO closure.
    • The procedural risks associated with AmplatzerTM TalismanTM PFO Occluder.
    • The need for adherence to a defined adjunctive antithrombotic therapy following implantation of the AmplatzerTM TalismanTM PFO Occluder.
    • Patients with a history of DVT or PE may benefit from continuation or resumption of anticoagulation therapy following implantation of the AmplatzerTM TalismanTM PFO Occluder to reduce the risk of recurrent DVT or PE.

    It is recommended that the medical team (neurologist and cardiologist) and the patient engage in a shared decision-making process and discuss the risks and benefits of PFO closure in comparison to using antithrombotic therapy alone, while taking into account the patient’s values and preferences.

  • SJM™ MASTERS SERIES
    MECHANICAL HEART VALVE


    The SJM™ Masters Series Mechanical Heart Valve is intended for use as a replacement valve in patients with a diseased, damaged, or malfunctioning aortic or mitral heart valve. This device may also be used to replace a previously implanted prosthetic heart valve.

    CONTRAINDICATIONS

    The SJM™ Masters Series Mechanical Heart Valve is contraindicated for individuals unable to tolerate anticoagulation therapy.

    WARNINGS

    • For single use only. Attempts to reuse the valve may result in valve malfunction, inadequate sterilization, or patient harm.
    • Do not use if:
      • The valve has been dropped, damaged, or mishandled in any way.
      • The expiration date has elapsed.
      • The tamper-evident container seal or inner/outer tray seals are damaged, broken or missing.
    • Remove any residual tissue that may impair valve size selection, correct seating of the valve, rotation of the valve, or leaflet motion.
    • Proper valve size selection is crucial. Do not oversize the valve. If the native annulus measurement falls between two SJM™ Masters Series Mechanical Heart Valve sizes, use the smaller size SJM™ Masters Series Mechanical Heart Valve.
    • Use only St. Jude Medical™ mechanical heart valve sizers.
    • The outer tray is not sterile, and should not be placed in the sterile field.
    • To minimize direct handling of the valve during implantation, do not remove the holder/rotator until the valve has been seated in the annulus.
    • Do not use hard or rigid instruments to test leaflet mobility, as this may result in structural damage to the valve or thromboembolic complications. Use a St. Jude Medical™ leaflet tester to gently test valve leaflet mobility.
    • Place sutures in the outer half of the valve sewing cuff.
    • Never apply force to the valve leaflets. Force may cause structural damage to the valve.
    • Use only SJM™ Valve Holder/Rotators to perform valve rotation. Use of other instruments could result in structural damage. The valve holder/ rotator is intended for single use only and should be discarded after surgery.
    • The two retention sutures on the valve holder/ rotator must be cut and removed before the SJM™ Masters Series Mechanical Heart Valve can be rotated.
    • Do not pass catheters or other instruments through St. Jude Medical™ mechanical heart valves. This could result in scratched or damaged valve components, or leaflet fracture or dislodgment.
    • Cut suture ends short, especially in the vicinity of the pivot guards, to prevent leaflet impingement.
    • Three cases of impeded leaflet motion not satisfactorily explained were reported in a survey of 149 centers reporting on 4,934 patients implanted over a period of three (3) years. A number of other cases occurred early in the investigation of this prosthesis; however, the rates of occurrence are not statistically determinable.

    PRECAUTIONS

    • Do not touch the prosthetic valve unnecessarily, even with gloved hands. This may cause scratches or surface imperfections that may lead to thrombus formation.
    • Be careful not to cut or tear the valve sewing cuff when removing the identification tag and the holder/rotator from the SJM™ Masters Series Mechanical Heart Valve.
    • Before placing sutures in the valve sewing cuff, verify that the valve is mounted correctly on the valve holder/rotator.
    • To avoid structural damage, the valve must be rotated in the fully closed position.
    • To minimize rotational torque, verify that the valve holder/rotator is properly seated in the valve, and that the valve holder handle is perpendicular to the valve (Figures 15a and 15b).
    • Remove any loose suture or thread, which may be a source of thrombus or thromboembolism.

    POTENTIAL ADVERSE EVENTS

    Complications associated with replacement mechanical heart valves include, but are not limited to:

    hemolysis; infections; thrombus; or thromboembolism; valve dehiscence; unacceptable hemodynamic performance; hemorrhagic complications secondary to anticoagulation therapy; prosthetic failure; and heart failure or death.

    Any of these complications may require reoperation or explantation of the device.

    • Requiring left ventriculotomy or an extensive right ventriculotomy.
    • With a failed previous VSD closure.
    • With multiple apical and/or anterior muscular VSDs (“Swiss cheese septum”).
    • With posterior apical VSDs covered by trabeculae.

    CONTRAINDICATIONS

    The AMPLATZER™ Muscular VSD Occluder is contraindicated for the following:

    • Patients with defects less than 4 mm distance from the semilunar (aortic and pulmonary) and atrioventricular valves (mitral and tricuspid)
    • Patients with severely increased pulmonary vascular resistance above 7 Wood units and a right-to-left shunt and documented irreversible pulmonary vascular disease
    • Patients with perimembranous (close to the aortic valve) VSD
    • Patients with post-infarction VSD
    • Patients who weigh less than 5.2 kg. (Patients smaller than 5.2 kg were studied in the clinical trial, but due to poor outcome, these patients have been contraindicated for device placement. Data from these patients has not been included in the overall analysis.)
    • Patients with sepsis (local/generalized)
    • Patients with active bacterial infections
    • Patients with contraindications to antiplatelet therapy or agents

    WARNINGS

    • The AMPLATZER™ Muscular VSD Occluder and delivery system should only be used by those physicians trained in transcatheter defect closure techniques.
    • Physicians must be prepared to deal with urgent situations, such as device embolization, which require removal of the device. This includes the availability of an on-site surgeon. 
    • Embolized devices must be removed. Embolized devices should not be withdrawn through intracardiac structures unless they have been adequately collapsed within a sheath.
    • Use on or before the last day of the expiration month noted on the product packaging.
    • The device is sterilized using ethylene oxide and is for single use only. Do not reuse or resterilize. Attempts to resterilize the device may result in device malfunction, inadequate sterilization, or patient harm.
    • Do not use the device if the packaging sterile barrier is open or damaged.
    • Do not release the AMPLATZER™ Muscular VSD Occluder from the delivery cable if the device does not conform to its original configuration or if the device position is unstable. Recapture the device and redeploy. If still unsatisfactory, recapture the device and replace with a new device.
    • Device closure in patients who have suffered a previous thromboembolic stroke should be discussed with the patient or family. In addition, consultation with a neurologist and hematologist is suggested to determine if the benefit of device closure outweighs the risk.

    PRECAUTIONS

    Handling
    Store in a dry place.

    Sizing
    Accurate defect sizing is crucial and mandatory for AMPLATZER™ Muscular VSD Occluder device selection. The VSD should be assessed and sized at end diastole by transesophogeal echocardiography (TEE) or angiography to determine the appropriate device size. Device selection should be 2 mm larger than the defect size.

    Procedural

    • This device contains nickel-titanium alloy, which is generally considered safe. However, in vitro testing has demonstrated that nickel is released from this device for a minimum of 60 days. Patients who are allergic to nickel may have an allergic reaction to this device, especially those with a history of metal allergies. Certain allergic reactions can be serious; patients should be instructed to seek medical assistance immediately if they suspect they are experiencing an allergic reaction. Symptoms may include difficulty in breathing or swelling of the face or throat. While data is currently limited, it is possible that some patients may develop an allergy to nickel if this device is implanted.
    • The physician should exercise clinical judgment in situations that involve the use of anticoagulants or antiplatelet drugs before, during, and/or after the use of this device.
    • This device should only be used by physicians who have been trained in transcatheter techniques and who should determine which patients are suitable candidates for procedures using this device.
    • Aspirin (eg, 81 mg or 325 mg) or an alternative antiplatelet/anticoagulant is recommended to be started at least 24 hours prior to the procedure. Cephalosporin therapy is optional. 
    • Maintain a recommended minimum active clotting time (ACT) of 200 seconds prior to device insertion and throughout the procedure.
    • If TEE is used, the patient’s esophogeal anatomy must be adequate for placement and manipulation of the TEE probe.
    • Patients requiring multiple devices and/or concomitant catheterization procedures might require prolonged fluoroscopy times and multiple cineangiograms. The risks of radiation exposure (eg, increased cancer risk) should be discussed in detail with the patient or family and alternatives which do not involve radiation exposure should be reviewed.

    Post-implant

    • Patients should be treated with antiplatelet/anticoagulation therapy (such as aspirin) for 6 months post-implant. The decision to continue antiplatelet/anticoagulation therapy beyond 6 months is at the discretion of the physician.
    • Endocarditis prophylaxis should be followed according to the American Heart Association recommendations.
    • Any patient who has a residual shunt should undergo an echocardiographic evaluation of the residual shunt every 6 months until complete closure of the defect has been confirmed.
    • Patients should be instructed to avoid strenuous activity for 1 month. Strenuous activities such as contact sports prior to 1 month after implant may cause the device to dislodge and embolize.

    Use in Specific Populations

    • Pregnancy - Care should be taken to minimize the radiation exposure to the fetus and the mother.
    • Nursing mothers - There has been no quantitative assessment of the presence of leachables from the device/procedure in breast milk, and the risk to nursing mothers is unknown.

    MR Conditional1
    Through non-clinical testing, AMPLATZER™ devices have been shown to be MR Conditional. A patient with an implanted AMPLATZER™ device can be scanned safely immediately after placement of the device under the following conditions:

    • Static magnetic field of 3 tesla or less
    • Spatial gradient magnetic field of 720 G/cm or less
    • Maximum MR system-reported, whole-body-averaged specific absorption rate (SAR) of 3 W/kg for 15 minutes of scanning

    During testing, the device produced a clinically non-significant temperature rise at a maximum MR system-reported, whole-body-averaged specific absorption rate (SAR) of 3 W/kg for 15 minutes of scanning in a 3 tesla MR system using a transmit/receive body coil.

    MR image quality may be compromised if the area of interest is in the exact same area or relatively close to the position of the device. Therefore, optimization of MR imaging parameters to compensate for the presence of this device may be necessary.

    POTENTIAL ADVERSE EVENTS

    Potential adverse events may occur during or after a procedure using this device may include, but are not limited to:

    Air embolus; Allergic drug reaction; Allergic dye reaction; Anemia; Anesthesia reactions; Apnea; Arrhythmia; Arterial pulse loss; Atelectasis; Bacterial endocarditis; Blood loss requiring transfusion; Brachial plexus injury; Cardiac arrest; Cardiomyopathy; Chest pain; Cyanosis; Death; Device embolization; Device fracture; Fever; Headache/migraine; Heart block; Hypotension; Myocardial infarction; Perforation of the vessel or myocardium; Peripheral embolism; Stridor; Stroke; Subaortic stenosis; Thrombus formation on device; Vascular access site injury; Venous thrombosis; Vomiting

    1. MR Conditional as defined in ASTM F 2503-05.
