Echocardiographic Assessment: Apical 4 Chamber
- Right atrial size (often dilated in setting of anomalous venous return)
- Right ventricular size and function (often dilated and hypertrophied)
- Pulmonary hypertension assessment (tricuspid regurgitation by color and spectral Doppler)
- Left atrial size (often small and underfilled)
- Left ventricular size (often small and underfilled)
- Pulmonary venous confluence (posterior to left atrium)
- Venous drainage into pulmonary venous confluence
- Assess individual veins (by 2D, color and spectral Doppler)
- Transducer at cardiac apex
- Notch at 3-4 o'clock (slight clockwise rotation)
- 4th or 5th intercostal space
- Probe tilted anteriorly (tail down)
