The estimation of right atrial pressure is often needed for the diagnosis, management and monitoring of various pathologic hemodynamic conditions and plays a significant role in patients with chronic heart failure. In the past decade several attempts have been made to non-invasively estimate right atrial pressure, and echocardiography has always been considered the most reliable tool. Morphologic parameters such as respiratory motion of the inferior vena cava, its respiratory diameters and percent collapse (caval index), left hepatic vein diameter or right atrial dimension (areas, volumes) were initially studied. More recently, functional data such as left hepatic or tricuspid flow variables have been considered. Some of these indexes, however, offer only semiquantitative measures of right atrial pressure, and have failed to demonstrate any prognostic value. Others, although highly sensitive and specific, are useful only in selected groups of patients because of technical or clinical limitations. In recent years, attention has focused on Doppler diastolic tricuspid flow as a means of predicting mean right atrial pressure. Analyzing the Doppler tricuspid velocity profile and mean right atrial pressure (Swan-Ganz catheter) simultaneously recorded in patients with severe left ventricular systolic dysfunction and chronic heart failure, acceleration rate of early filling emerged as the strongest independent predictor of right atrial pressure both in patients in sinus rhythm and in those with atrial fibrillation (r = 0.98), irrespective of whether the recordings are at baseline or after acute loading manipulations.
