Ventricular Pressure-Volume Loop Changes in Valve Disease

Cardiac valve disease significantly alters ventricular pressure and volume relationships during the cardiac cycle. A convenient way to analyze cardiac pressure and volume changes is by using ventricular pressure-volume loops. The links below will illustrate the pressure-volume changes that occur with the the following valve defects:

Mitral stenosis

Aortic stenosis

Mitral regurgitation

Aortic regurgitation
