Closure of a Late‐Onset Iatrogenic Left Ventricular Pseudoaneurysm Caused by Erosion of an Apical Muscular VSD Device

Abstract

We report the case of a 3‐year‐old asymptomatic girl (12 kg, 96 cm) who was diagnosed with a large iatrogenic left ventricular pseudoaneurysm (LVP) on follow‐up ultrasound, 14 months after apical muscular ventricular septal defect (VSD) closure with a 10 mm Amplatzer Muscular VSD occluder (Abbott, USA) due to device erosion. The LVP was successfully occluded using detachable Penumbra coils, with complete thrombo‐exclusion confirmed at 12‐month follow‐up.
