title: A modified Cook sheath for closure of a large secundum atrial septal defect.
abstract: Transcatheter closure of large secundum atrial septal defects with deficient rims is difficult. Several techniques have been described to improve delivery of the occluder in anatomically challenging cases. Among these is a recently described technique using a modified delivery sheath with the creation of a bevel. However, the initial case report was complicated by malfunction and longitudinal splitting of the sheath. We describe the successful use of a modified delivery sheath for closure of a large atrial septal defect with a deficient rim.
