- Conoventricular VSD: A hole where portions of the ventricular septum should meet just below the pulmonary and aortic valves
- Perimembranous VSD: A hole in the upper section of the ventricular septum

- Muscular VSD: A hole in the lower, muscular part of the ventricular septum and is the most common type of VSD
