Classification
Small VSDs
There is a small left-to-right shunt (Qp/Qs < 1.5) and a normal ratio of PA to systemic pressures.
Medium-Sized VSDs
There is a moderate shunt left-to-right present (Qp/Qs = 1.5-2.0) that still has some resistance to flow across the defect.
Large VSDs
There is a large defect on the ventricular septum, > 1 cm2/m2 of BSA, with a large shunt left-to-right (Qp/Qs is > 2), causing volume overload of the LV, which may result in its failure. The defect may approximate the size of the aortic orifice.
