Echocardiography
Echocardiography
- Echocardiography is most useful for diagnosis and management of AVSD and is usually best achieved from the apical four-chamber view and subcostal view:
- Presence and size of atrial-level defect and shunt
- Presence and size of ventricular-level defect and shunt
- Anatomy of the atrioventricular valve (AVV), including annulus size
- Leaflet morphology, chordal attachments and papillary muscle architecture.the degree of atrioventricular valve regurgitation, left sided component of the atrioventricular valve, chordal insertions of the valve, patency of the outflow tracts and the relative ventricular sizes. With the addition of color flow Doppler, the assessment of atrial level and ventricular level shunting can be made.
