title: Spectral Doppler interrogation of mitral regurgitation -spot diagnosis.
abstract: 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.
