Overview
The doppler is an effective imaging modality to show an ASD, as well as other details such as the defect size, the direction of flow, the speed of the flow, and what therapies might be of best use. There are some disadvantages to the use of doppler.
Doppler
- Used to demonstrate left to right flow.
- Effective modality for:
- Confirmation of a suspected atrial septal defect.
- Estimation of the defect size.
- Determination of the universal direction of flow across the septum.
- Determination of the usage of percutaneous closure and surgical therapies.
- Determination of high velocity flow, useful in patients with restrictive defects, obstructed pulmonary venous return and/or left atrial hypertension.
Disadvantages
- May show false positive shunting as caval flow and incorrectly set gain may appear as left to right flow.
- Coloring across the interatrial septum can distort the perception of the shunt flow.
- Not effective in determination of sinus venosus defects.
