List of terms related to Ventricular septal defect

	Ventricular septal defect;
	Echocardiographic image of a moderate ventricular septal defect in the mid-muscular part of the septum. The trace in the lower left shows the flow during one complete cardiac cycle and the red mark the time in the cardiac cycle that the image was captured. Colours are used to represent the velocity of the blood. Flow is from the left ventricle (right on image) to the right ventricle (left on image). The size and position is typical for a VSD in the newborn period.
