Pulmonary venous flow can be evaluated by means of pulsed Doppler echocardiography during a transthoracic or transesophageal echocardiography examination. In most cases a three-peak spectral curve with highest positive wave during ventricular systole, a lower positive wave during ventricular diastole and a small negative wave during the left atrial contraction are recorded. Multiple factors affect the systolic and diastolic components of pulmonary venous flow. Pulmonary venous flow measurement may prove to be an important tool in routine judgment of diastolic left ventricular and atrial function. With regard to clinical importance, the pulmonary venous flow is a useful parameter for left atrial pressure quantification and for differential diagnosis of restrictive cardiomyopathy and constrictive pericarditis.
在经胸或经食管超声心动图检查期间，可通过脉冲多普勒超声心动图评估肺静脉血流。在大多数情况下，记录到的频谱曲线有三个波峰，心室收缩期出现最高正向波，心室舒张期出现较低正向波，左心房收缩期出现小的负向波。多种因素影响肺静脉血流的收缩期和舒张期成分。肺静脉血流测量可能是常规判断左心室舒张功能和心房功能的重要工具。就临床重要性而言，肺静脉血流是用于量化左心房压力以及鉴别诊断限制性心肌病和缩窄性心包炎的有用参数。
