Interatrial septum dissection and closure from transseptal puncture during mitral transcatheter edge-to-edge repair: a case report.

ABSTRACT:

Background

An 85-year-old woman was referred for mitral valve transcatheter edge-to-edge repair (TEER) following multiple heart failure hospitalizations related to her severe functional mitral regurgitation. In addition to previous transcatheter aortic valve replacement for aortic stenosis, her past medical history was significant for chronic steroid use related to microscopic polyangiitis leading to renal transplantation.

Case summary

Her procedure was complicated by an interatrial septum dissection with associated haemopericardium originating from the transseptal puncture site. To our knowledge, our case demonstrates the first use of an Amplatzer occluder device to manage this complication by preventing ongoing flow into the pericardial space. This complication occurred in
