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 extends 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]
Echocardiogram
Two dimensional echo(2D) can be used to visualize the defects, and with pulsed wave and color doppler the sensitivity is 90%. The velocity across the defect can be used to calculate the gradient, and calculate the RV and PA pressures.
