The Amplatzer Septal Occluder effectively treats interatrial communications, including atrial septal defects and patent foramen ovale, with high occlusion rates and minimal complications in 150 patients. Long-term data is pending for this widely adopted device.

Area of Science:

  • Cardiology
  • Medical Devices
  • Interventional Cardiology

Background:

  • Interatrial communications require effective closure devices.
  • The Amplatzer Septal Occluder offers a Nitinol wire mesh design for occluding septal defects.

Purpose of the Study:

  • To evaluate the clinical experience and outcomes of using the Amplatzer device in 150 patients with various interatrial communications.

Main Methods:

  • Retrospective analysis of 150 patients treated with the Amplatzer Septal Occluder for atrial septal defects, patent foramen ovale, and Fontan fenestrations.
  • Assessment of device efficacy, complications, and occlusion rates through follow-up procedures.

Main Results:

  • High occlusion rates (90% at 1 year) were achieved in atrial septal defects.

  • Successful closure of patent foramen ovale and Fontan fenestrations with minimal residual shunts.
  • Complications included device migration, deep vein thrombosis, and transient arrhythmias in a small number of patients.

    • Conclusions:

    • The Amplatzer Septal Occluder demonstrates encouraging efficacy and ease of use for interatrial communications.
    • While widely adopted, long-term follow-up data is essential for this lifelong implant.
