Left atrial appendage occlusion guided by intracardiac echocardiography in a patient with a 34 mm atrial septal defect occluder: a case report.

ABSTRACT:

Background

Intracardiac echocardiography (ICE)-guided left atrial appendage occlusion (LAAO) is increasingly common. Patients with previous atrial septal defect closure constitute a significant challenge for transseptal access.

Case summary

A 49-year-old man with persistent atrial fibrillation, hypertension, and reduced left ventricular function was considered for LAAO after a life-threatening intrathoracic bleeding while on oral anticoagulation. Percutaneous atrial septal defect closure was performed 15 years before with a 34 mm Amplatzer Septal Occluder. Preprocedural cardiac computed tomography demonstrated the atrial septal occluder device with a small native interatrial septum at the inferior margin. The left atrial appendage landing zone measured 17 × 22 mm. The LAAO w
