May allow RAP to estimate pericardial pressure for LV preload assessment in cardiac surgery; leaves open prospective validation.
Can right atrial pressure be used as an estimate of pericardial surface pressure in patients undergoing cardiac surgery?
Right atrial pressure closely estimates pericardial surface pressure, suggesting true left ventricular preload could be estimated from the difference between left ventricular filling pressure and right atrial pressure.
Tyberg et al. (1986) studied this question.
