Mitral regurgitation ( MR ) is one of the most common valvular lesions that are readily identified by transthoracic echocardiography. Color Doppler imaging is the modality of choice for the recognition of MR , and it plays an important role in the assessment of regurgitation severity. Continuous wave ( CW ) Doppler is commonly used to interrogate the MR signal, and this modality can provide highly useful data regarding several physiological and pathological parameters. In this manuscript, we present a series of cases that illustrate the various hemodynamic parameters that can be derived from analysis of the CW Doppler signal of MR .
