Chiari Network: Cause of an Unusual Difficulty during Atrial Septal Defect Device Closure

Abstract

We report an unusual difficulty in unscrewing and releasing the atrial septal defect device during device closure because of the entrapment of the delivery cable in the prominent Chiari network. We suggest careful pre- and intra-procedure transesophageal guidance in recognizing and managing this rare challenge.
