New solution for old challenge: Device closure of non-centrally positioned atrial septal defect

Abstract

Multiple interatrial defects, termed fenestrated ASDs that require closure are not uncommon. The problem arises when a centrally located defect or a patent foramen oval (PFO) is associated with another peripherally located defect. In cases like this, all attempts at crossing the true defect might totally fail or might be difficult because the wire or the catheter crosses the central defect repeatedly despite the use of a sizing balloon. In order to overcome such an issue, we introduce a new technique by which not only the procedure and the fluoroscopy time will be reduced, but also it ceases the mistakes about the number of defects, their size and location.
