Echocardiography along with Doppler color flow mapping act as an important diagnostic tool in identifying ventricular septal defect (VSD). The different types of VSD on Echocardiography have the following features-

  • Perimembranous VSD - septal dropout in areas of septal leaflet of tricuspid valve and below right border of aortic annulus.
  • Anterior malalignment- appears below the posterior semilunar valve
  • Subpulmonary VSD- Appear as ECHO dropout within outflow septum and extending to the pulmonary annulus.
  • Inlet AV septal- extends from fibrous annulus of tricuspid valve into the muscular septum
  • Muscular defect- can occur anywhere in the septum and could be small, large, single or multiple


ECHO also helps in calculating pulmonary and systemic flow from arterial velocity profile and cross-sectional area of great vessels. [1]
