A 45-year-old female patient presented with a history of tiredness and dyspnea on exertion for the past year. On physical exam, the patient was short of breath and had pitting edema in both lower extremities around her ankles. On auscultation, a pan systolic murmur was heard which was best heard in the apical region. A POCUS cardiac exam was performed by the physician and the following was an apical 4 chamber view obtained with the color Doppler box overlay in the region of the mitral valve and the left atrium.
Question: What does this color Doppler indicate?
A) Normal color Doppler flow of blood from the LA to the LV during LV diastole.

C) The blue color indicates reverse flow from the LV into the LA and is consistent with MV
regurgitation.
