:: Type 3 are inlet VSDs, located beneath both mitral and tricuspid valves. Despite proximity to those valves, this type of defect is not associated with mitral or tricuspid regurgitation unless associated with atrioventricular canal defect. This typically large defect is often associated with Down syndrome. | :: Type 3 are inlet VSDs, located beneath both mitral and tricuspid valves.

:: Muscular defects (type 4) are located within the trabecular septum and accounts for 5 – 20% of all VSDs. It is bordered only by muscle, away from the cardiac valves. Muscular defects can be small or large in size and consist of a single or multiple defects. | :: Muscular defects (type 4) are located within the trabecular septum and accounts for 5 – 20% of all VSDs.
