Data obtained from echocardiographic studies are used on a daily basis to guide clinical decision-making regarding patient management and the need for additional diagnostic investigations. Interrogation of blood flow in the pulmonary veins by spectral, most often pulsed-wave, Doppler is an important component of any comprehensive echocardiographic study. Whereas it is most often used to help assess left-sided filling pressure and quantify the severity of mitral regurgitation, the pulmonary vein Doppler profile provides added diagnostic insights into several disorders that affect heart function and allows assessment of their hemodynamic consequences on the heart. The aim of this review is to summarize current knowledge in the field of PV Doppler interrogation, highlight the physiological and pathological parameters that influence it, and delineate the manifestations of various cardiovascular disorders on the flow profile.
