The Amplatzer™ portfolio of structural interventions occluders provides minimally invasive treatment options for the closure of congenital heart defects. These closure devices are performed through a transcatheter approach, which prevents the need for heart surgery and enables faster recovery times.

Amplatzer™ Septal Occluders

Amplatzer™ Septal Occluders are the standard of care for minimally invasive ASD closure. These double-disc occluders are comprised of Nitinol mesh with polyester fabric. They are designed to securely appose the septal wall on each side of the defect and create a platform for tissue in-growth after implantation.

Amplatzer™ Muscular VSD Occluders

Ventricular septal defects are the most commonly found congenital heart defect.1 If left untreated it can lead to pulmonary hypertension and/or congestive heart failure.2 The Amplatzer™ Muscular VSD Occluders are designed for complete closure of these type of defects.

Amplatzer™ Duct Occluders

The Amplatzer™ Family of Duct Occluders offers an extensive line of devices and a simple treatment option for the closure of PDA. Each duct occluder has been designed to occlude PDAs of various shapes and sizes. With an easy-to-perform deployment procedure, the implanting physician can be confident in placing the device with precision.

Amplatzer™ PFO Occluder

The Amplatzer™ PFO Occluder set the standard, pioneering treatment with a device developed specifically for PFO closure. It’s the leading PFO closure device to date, with over 100,000 devices implanted worldwide.3

Important Safety Information

rx-only-logo AMPLATZER™ SEPTAL OCCLUDER

 

Indications for Use
The AMPLATZER™ Septal Occluder is a percutaneous, transcatheter, atrial septal defect closure device intended for the occlusion of atrial septal defects (ASD) in secundum position or patients who have undergone a fenestrated Fontan procedure and who now require closure of the fenestration. Patients indicated for ASD closure have echocardiographic evidence of ostium secundum atrial septal defect and clinical evidence of right ventricular volume overload (such as, 1.5:1 degree of left-to-right shunt or RV enlargement).

Contraindications

  • The AMPLATZER™ Septal Occluder is contraindicated for the following:
  • Any patient known to have extensive congenital cardiac anomaly which can only be adequately repaired by way of cardiac surgery.
  • Any patient known to have sepsis within 1 month prior to implantation, or any systemic infection that cannot be successfully treated prior to device placement.
  • Any patient known to have a bleeding disorder, untreated ulcer, or any other contraindications to aspirin therapy, unless another antiplatelet agent can be administered for 6 months.
  • Any patient known to have a demonstrated intracardiac thrombi on chocardiography (especially left atrial or left atrial appendage thrombi).
  • Any patient whose size (such as, too small for transesophageal echocardiography probe, catheter size) or condition (active infection, etc.) would cause the patient to be a poor candidate for cardiac catheterization.
  • Any patient where the margins of the defect are less than 5 mm to the coronary sinus, inferior vena cava rim, AV valves, or right upper lobe pulmonary vein.

Warnings

  • 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 as they may disrupt critical cardiac functions. Embolized devices should not be withdrawn through intracardiac structures unless they have been adequately collapsed within the sheath.
  • Use on or before the expiration date noted on the product packaging.
  • This 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™ Septal Occluder from the delivery cable if the device does not conform to its original configuration, or if the device position is unstable or if the device interferes with any adjacent cardiac structure (such as Superior Vena Cava (SVC), Pulmonary Vein (PV), Mitral Valve (MV), Coronary Sinus (CS), aorta (AO)). Recapture the device and redeploy. If still unsatisfactory, recapture the device and either replace with a new device or refer the patient for alternative treatment.
  • Implantation of this device may not supplant the need for Coumadin‡ in patients with ASD and paradoxical emboli.
  • The use of echocardiographic imaging (TTE, TEE, or ICE) is required.
  • Balloon sizing should be used to size the atrial septal defect using a stop-flow technique. Do not inflate the balloon beyond the cessation of the shunt (such as, stop-flow). DO NOT OVERINFLATE.
  • Patients with a retro-aortic rim of less than 5 mm in any echocardiographic plane, or patients in whom the device physically impinges on (i.e. indents or distorts) the aortic root, may be at increased risk of erosion.
  • Do not select a device size greater than 1.5 times the echocardiographic-derived ASD diameter prior to balloon sizing.

Precautions

  • The use of this device has not been studied in patients with patent foramen ovale.
  • Use standard interventional cardiac catheterization techniques to place this device.
  • Placement of the AMPLATZER™ Septal Occluder may impact future cardiac interventions, for example transeptal puncture and mitral valve repair.

High-risk anatomical factors for transatrial or transarterial surgical closure include patients:

  • 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

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.

  • 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 1month 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.

Some forms of nickel have also been associated with carcinogenicity (ability to cause cancer) in animal models. In humans, carcinogenicity has been demonstrated only through an inhalation route (breathing nickel in) which will not occur with this procedure.
  • 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.

Post-implant

  • Endocarditis prophylaxis is carried out for 6 months according to the recommendation of the American Heart Association. The decision to continue endocarditis prophylaxis beyond 6 months is at the discretion of the physician.
  • Any patient who has a residual shunt will undergo an echo cardiographic evaluation of the residual shunt until complete closure of the defect has been confirmed.
  • Lung perfusion scan should be completed if flow through is greater than 3 m/s, or if the Z-score is -2 for the left pulmonary artery diameter.
  • MR Conditional to 3.0 Tesla
  • Through nonclinical testing, the AMPLATZER™ device has been known to be MR Conditional at field strengths of 3.0 tesla or less with a maximum whole-body-averaged specific absorption rate (SAR) of 3.83 W/kg at 1.5 tesla and 5.57 W/kg at 5.0 tesla for a 20-minute exposure to a B1 of 118μ tesla. The AMPLATZER™ device should not migrate in this MR environment. Nonclinical testing has not been performed to rule out the possibility of migration at field strengths higher than 3.0 tesla.
  • In this testing, the device produced a temperature rise of 1.1°C at 1.5 tesla and 1.6°C at 5.0 tesla.
  • 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.

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 in breast milk

MR Conditional

  • Abbott Medical's AMPLATZER™ Duct Occluder II device is manufactured of chemically etched nitinol wire, 80% platinum 20% iridium marker band and a 316L end screw
  • Non-clinical testing has demonstrated that the AMPLATZER™ Duct Occluder II device is MR-Conditional. Patients can be scanned safely immediately after implantation under the following conditions:
    • Static magnetic field of 1.5 Tesla (1.5T) or 3.0-Tesla (3.0T).
    • Maximum spatial gradient field less than or equal to 30 T/m.
    • Maximum whole-body-averaged specific absorption rate (SAR) of 2.0 W/kg (normal operating mode) for 15 minutes of scanning
  • In non-clinical testing with body coil excitation, the AMPLATZER™ Duct Occluder II device produced a differential temperature rise of less than or equal to 3.65ºC when exposed to a maximum average whole body specific absorption rate (SAR) of 3.35 W/kg for 15 minutes of scanning in a 3.0-Tesla MR system (Siemens MAGNETOM Trio‡, SYNGO‡ MR A35 4VA35A software, Erlangen, Germany). Scaling of the SAR and observed heating indicates that average whole body SAR of 2.0 W/kg would be expected to yield a localized temperature rise of less than or equal to 1.0ºC in Normal Operating Mode.
  • In non-clinical testing with body coil excitation, the AMPLATZER™ Duct Occluder II device produced a differential temperature rise of less than or equal to 1.91ºC when exposed to a maximum average whole body specific absorption rate (SAR) of 2.80 W/kg for 15 minutes of scanning in a 1.5-Tesla MR system (Siemens‡ MAGNETOM Espree‡, SYNGO‡ MR B17 software, Erlangen, Germany).Scaling of the SAR and observed heating indicates that average whole body SAR of 2.0W/kg would be expected to yield a localized temperature rise of less than or equal to approximately 1.0 ºC in Normal Operating Mode.

rx-only-logoAMPLATZER™ PFO OCCLUDER

Indications and Usage

The AMPLATZER™ PFO Occluder is indicated for percutaneous transcatheter closure of a patent foramen ovale (PFO) to reduce the risk of recurrent ischemic stroke in patients, predominantly between the ages of 18 and 60 years, who have had a cryptogenic stroke due to a presumed paradoxical embolism, as determined by a neurologist and cardiologist following an evaluation to exclude known causes of ischemic stroke.

Contraindications

  • Patients with intra-cardiac mass, vegetation, tumor or thrombus at the intended site of implant, or documented evidence of venous thrombus in the vessels through which access to the PFO is gained.
  • Patients whose vasculature, through which access to the PFO is gained, is inadequate to accommodate the appropriate sheath size.
    Patients with anatomy in which the AMPLATZER™ PFO device size required would interfere with other intracardiac or intravascular structures, such as valves or pulmonary veins.
  • Patients with other source of right-to-left shunts, including an atrial septal defect and/or fenestrated septum.
  • Patients with active endocarditis or other untreated infections.

Warnings

  • Patients who are at increased risk for venous thromboembolic events should be managed with thromboembolic risk reduction regimen after the PFO Closure following standard of care.
  • Do not use this device if the sterile package is open or damaged.
  • Prepare for situations that require percutaneous or surgical removal of this device. This includes availability of a surgeon.
  • Embolized devices must be removed as they may disrupt critical cardiac functions. Do not remove an embolized occluder through intracardiac structures unless the occluder is fully recaptured inside a catheter or sheath.
  • Patients who are allergic to nickel can have an allergic reaction to this device.
  • This device should be used only by physicians who are trained in standard transcatheter techniques.
  • Transient hemodynamic compromise may be encountered during device placement, which may require fluid replacement or other medications as determined by the physician.
  • Do not release the device from the delivery cable if the device does not conform to its original configuration, or if the device position is unstable or if the device interferes with any adjacent cardiac structure (such as Superior Vena Cava (SVC), Pulmonary Vein (PV), Mitral Valve (MV), Coronary Sinus (CS), aorta (AO)). If the device interferes with an adjacent cardiac structure, recapture the device and redeploy. If still unsatisfactory, recapture the device and either replace with a new device or refer the patient for alternative treatment.
  • Ensure there is sufficient distance from the PFO to the aortic root or SVC (typically defined as 9 mm or greater as measured by echo). See Figure 6. and Figure 7.

Precautions

  • The safety and effectiveness of the AMPLATZER™ PFO Occluder has not been established in patients (with):
    • Age less than 18 years or greater than 60 years because enrollment in the pivotal study (the RESPECT trial) was limited to patients 18 to 60 years old
    • A hypercoagulable state including those with a positive test for a anticardiolipin antibody (IgG or IgM), Lupus anticoagulant, beta-2 glycoprotein-1 antibodies, or persistently elevated fasting plasma homocysteine despite medical therapy
    • Unable to take antiplatelet therapy
    • Atherosclerosis or other arteriopathy of the intracranial and extracranial vessels associated with a ≥50% luminal stenosis
    • Acute or recent (within 6 months) myocardial infarction or unstable angina
    • Left ventricular aneurysm or akinesis
    • Mitral valve stenosis or severe mitral regurgitation irrespective of etiology
    • Aortic valve stenosis (mean gradient greater than 40 mmHg) or severe aortic valve regurgitation
    • Mitral or aortic valve vegetation or prosthesis
    • Aortic arch plaques protruding greater than 4 mm into the aortic lumen
    • Left ventricular dilated cardiomyopathy with left ventricular ejection fraction (LVEF) less than 35%
    • Chronic, persistent, or paroxysmal atrial fibrillation or atrial flutter
