Closure of Secundum Atrial Septal Defects With the AMPLATZER Septal Occluder: A Prospective, Multicenter, Post-Approval Study.

Abstract

BACKGROUND:

Prospective data on the medium-term safety and effectiveness of the AMPLATZER Septal Occluder in clinical practice are not available. The objective of this study was to prospectively evaluate the risk of hemodynamic compromise and obtain medium-term survival data on patients implanted with the AMPLATZER Septal Occluder for percutaneous closure of secundum atrial septal defects.

METHODS AND RESULTS:

Subjects were enrolled prospectively at 50 US sites and followed for 2 years. Between 2008 and 2012, atrial septal defect closure with the AMPLATZER Septal Occluder was attempted in 1000 patients (aged 0.3-83.6 years, mean 21±22 years). Procedural closure occurred in 97.9%, with 1-month and 2-year closure 98.5% and 97.9%, respectively. Hemodynamic compromise occurred in 6 subjects (0.65%), because of dysrhythmia in 2, device embolization in 1, and cardiac erosion in 3. The rate of cardiac erosion was 0.3% (average 83, range 12-171 days from implant).

CONCLUSIONS:

Closure of atrial septal defect with the AMPLATZER Septal Occluder is safe and effective. The rate of hemodynamic compromise and cardiac erosion is rare. The risk factors for cardiac erosion after device closure are not yet clear.
