Use of Mullins sheath to prevent prolapse of Gore Cardioform ASD Occluder in a child with severe scoliosis

Abstract

Transcatheter device closure of an atrial septal defect (ASD) may require an additional supportive technique in challenging cases. We report a 15-year-old male with moderate-sized ASD and severe scoliosis. In spite of adequate positioning of the Gore Cardioform ASD occluder, the device was pulled into the right atrium by a retrieval cord due to the acute release of strong tension between the delivery catheter and its device upon locking. This phenomenon was prevented by the use of Mullins sheath, resulting in a successful release of the device. The use of a Mullins sheath may be considered to deliver a Gore Cardioform ASD device in selected cases.

Keywords: Gore Cardioform ASD Occluder; Key atrial septal defect; Mullins sheath.
