Transseptal approach in children after patch occlusion of atrial septal defect: first experience with the cutting balloon.

Two children required a transseptal approach to the left heart for endovascular stent redilation late after pericardial patch closure of atrial septal defects performed at the time of their initial surgical intervention. Following perforation of thickened interatrial patches in both patients, cutting balloons were used to create adequate interatrial communications. Cathet. Cardiovasc. Intervent. 48:378-381, 1999.
