Figure 45. Echo-Doppler studies in apical four-chamber (A, B) and parasternal long-axis (C) projections demonstrating a very small ventricular septal defect (VSD) (arrows in A-C) with increased flow velocity through the VSD by continuous wave Doppler (D). Note partial occlusion of the VSD (A) due to aneurismal formation. The left atrium (LA) and left ventricle (LV) are labeled. Reproduced from Ref.^[34].
