Key result
The relationship between estimated left atrial volume and resting right heart and wedge pressures was evaluated in 20 patients with mitral stenosis.
Why the study?
What is the relationship between left atrial volume and pulmonary artery and wedge pressures in patients with mitral stenosis?

What is the relationship between left atrial volume and pulmonary artery and wedge pressures in patients with mitral stenosis?
This study evaluates the hemodynamic correlation between left atrial volume and right-sided and wedge pressures in patients with mitral stenosis.
May support noninvasive pressure estimation in mitral stenosis; hypothesis-generating and requires prospective validation.
The significance of left atrial volume has been studied in 20 consecutive patients with mitral stenosis. Cardiac catheterization was performed and resting pressures in the right atrium, right ventricle, and pulmonary artery, as well as wedge pressure, were determined. Angiocardiography was performed immediately after cardiac catheterization. On the basis of these data the relationship between the estimated left atrial volume and these pressures is stated.

Soloff et al. (1957) conducted an observational in Mitral stenosis (n=20). Left atrial volume was evaluated on Relationship between estimated left atrial volume and resting pressures (right atrium, right ventricle, pulmonary artery, wedge pressure). The relationship between estimated left atrial volume and resting right heart and wedge pressures was evaluated in 20 patients with mitral stenosis.
