After percutaneous left atrial appendage (LAA) closure with the Amplatzer cardiac plug (ACP), an intriguing image in the shape of the number eight (figure-of-eight) is frequently observed on electrocardiography. This phenomenon is an image artifact that results from an interaction between the metal mesh of the ACP and the ultrasound waves. This finding should not be interpreted as a sign of incorrect ACP implantation.

Background: Mechanical occlusion of the Left atrial appendage (LAA) using a purpose-built device has emerged as an effective prophylactic treatment in patients with atrial fibrillation at risk of stroke and a contraindication for anticoagulation. A crucial step in procedural planning is the choice of the device size. This is currently based on the manual analysis of the “Device Landing Zone” fr...

Congenital defects of the pericardium are considered rare. Until 1979 , the reported cases were only about 200.1 Total absence of the left pericardium is the most common defect2 and less common is a partial defect of the left pericardium. Other types, i.e. isolated right-sided defects, total pericardial absence and diaphragmatic pericardial defects are very rare.3 Before the last decade, t...
