Left atrial appendage closure in a patient previously implanted with an interatrial shunt device: a case report

Dawei Lin et al. BMC Cardiovasc Disord. .

Abstract

Patients with previous interatrial shunt device (IASD) implantation may face greater challenges during future left atrial interventional procedures. Herein, we report the first case of left atrial appendage closure (LAAC) in a patient with previous IASD implantation. The patient successfully underwent LAAC using the LAmbre device without complications.

Keywords: FreeFlow®; Interatrial shunt device (IASD); LAmbre device; Left atrial appendage closure (LAAC).
