Case ReportsChiari network entanglement and herniation into the left atrium by an atrial septal defect occluder device.
The Chiari network is a fenestrated membrane consisting of threads and strands in the right atrium. First described in 1897 by anatomist Hans Chiari, it is a congenital remnant of embryonic development resulting from incomplete resorption of the right valve of the sinus venosus. ⋯ We report the entanglement of an Amplatzer septal occluder device catheter in a prominent Chiari network that was herniated into the left atrium. Transesophageal echocardiographic recognition of this before deployment and guidance during disentanglement is described below.
