title: A novel method to create atrial septal defect using a cutting balloon in piglets.
abstract: A new method of creating atrial septal defect, using a 3- or 4-blade cutting balloon catheter combined with conventional static balloon dilation, is discussed. Radially directed surgical cuts made in the atrial septum were enlarged by balloon angioplasty, producing defects measuring 3 to 8 mm, with a mean Qp/Qs of 1.96/L.
