Background What is a Ostium Secundum Atrial Septal Defect? What is a Ostium Secundum Atrial Septal Defect? congenital heart disease congenital heart disease causes left to right shunting across interatrial septum causes left to right shunting across interatrial septum Why should we care? Why should we care? Isolated secundum atrial septal defects of significance occur in approximately 70, ,000 individuals today.Isolated secundum atrial septal defects of significance occur in approximately 70, ,000 individuals today. Isolated ASDs can cause congestive heart failure or Eisenmengers syndromeIsolated ASDs can cause congestive heart failure or Eisenmengers syndrome

Techniques Used Today Surgical Suture & Surgical Patch Surgical Suture & Surgical Patch Both require open heart surgeryBoth require open heart surgery Requires stopping the patient's heart and utilizing cardiopulmonary bypassRequires stopping the patient's heart and utilizing cardiopulmonary bypass Transcatheter Amplatzer septal occluder Transcatheter Amplatzer septal occluder Pioneer in 1976Pioneer in 1976 Minimally invasive with excellent resultsMinimally invasive with excellent results
