Use of the Occlutech pmVSD Device for Hybrid Closure of a Large Mid-Muscular Ventricular Septal Defect in a Small Infant Born With Hypoplastic Aortic Arch

We describe the perventricular device closure of a large mid-muscular ventricular septal defect (VSD) in a 2.9 kg infant born with hypoplastic aortic arch and VSD using an Occlutech perimembranous occluder. In this case, the anatomy required a short low-profile device and hence a perimembranous occluder was used. To our knowledge, this is the first described use of this device for hybrid closure of a muscular VSD and the application of this technique in a patient <3 kg.
