AMPLATZER™ SEPTAL OCCLUDER CLINICAL DATA

The primary treatment option for atrial septal defects (ASD) is percutaneous, transcatheter closure, and the Amplatzer™ Septal Occluder is the proven standard of care1,2—with more than 20 years of global clinical experience in ASD closure.3

GREATER SAFETY COMPARED WITH SURGICAL CLOSURE


The Amplatzer™ Septal Occluder is the most studied transcatheter atrial septal defect (ASD) closure device available today, with over 20 years of demonstrated clinical experience.1,2

The following 3 studies, together, cover over 1,500 patient-years of device experience.2-4

The Amplatzer™ Septal Occluder is the most studied transcatheter atrial septal defect (ASD) closure device available today

U.S. PIVOTAL TRIAL: LOWER RATES OF ADVERSE EVENTS VS SURGERY2

This study was conducted to determine the safety and efficacy of transcatheter ASD closure involving 442 device-closure patients and 911.5 total patient-years of device experience.2 The U.S. Pivotal Trial revealed:

  • An adverse event rate 3 times lower for Amplatzer Septal Occluder as compared to surgical closure
  • No erosion events
