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.
经导管闭合边缘缺损的大型继发孔型房间隔缺损具有挑战性。已有多种技术被描述用于在解剖结构复杂的病例中改善封堵器的输送。其中一种是最近描述的使用带有斜面的改良输送鞘管的技术。然而,最初的病例报告因鞘管故障和纵向裂开而复杂化。我们描述了成功使用改良输送鞘管闭合边缘缺损的大型房间隔缺损的情况。
