Relationship of Pulmonary Venous Flow Pattern to Mean Left Atrial Pressure and Phasic Pressure Change

摘要: To assess the correlation of pulmonary venous flow pattern with magnitude dynamic change in left atrial pressure (i.e. x and y descents) to elucidate way how reflects pressure, we studied 35 patients normal sinus rhythm undergoing transesophageal echocardiography cardiac catheterization. The ratio peak systolic/diastolic correlated well x/y descent (r = 0.88) velocity-time integral 0.89). between or mean was less strong -0.49 -0.70, respectively). We conclude that velocity, phasic more appropriately than pressure. Due good pattern, veins could be used identify diseases specific patterns
