Figure 13From: Ventricular septal defectThe cross-sectional echocardiogram, taken in slightly off axis four chamber projections, shows an apical muscular ventricular septal defect (white arrow) in the left hand panel of Figure 13a. The right hand panel shows the Doppler color flow map of a hemodynamically restrictive muscular ventricular septal defect. The apical five chamber view, shown in Figure 13b, shows the Doppler color flow map of an apical muscular ventricular septal defect (white arrow).Back to article page
