Answer

The Doppler method can be used to detect distorted blood flow and certain types of cardiac pathology not otherwise visualized by standard echocardiography. It is good for visualizing jet lesions and differentiating cusp perforation from valvular insufficiency.

The combination of TEE and color Doppler is excellent for detecting intracardiac fistulas. The resolution of both TEE and TTE in real time is approximately 2 mm.
