Membranous VSD

Amplatzer Membranous VSD Occluder
The Amplatzer Membranous VSD Occluder is intended for occlusion of hemodynamically significant perimembranous VSDs. These VSDs are adjacent to the tricuspid valve’s septal leaflet, or adjacent to the aortic valve. This is the most common VSD subtype, occurring in 80% of cases.1
This occluder’s non-concentric design allows for placement while avoiding interference with the aortic or atrioventricular valves.
With sizes that increase by 1-mm increments, the Amplatzer Membranous VSD Occluder is available from 4 to 18 mm.
For implantation of this device, hemodynamic significance is defined as:
