1 Ventricular Pressure loop Filling Stroke volume Aortic valve closes Isovolumic relaxation Ejection Isovolumic contraction Volume (ml) Pressure (mmHg) Mitral valve opens Mitral valve closes Aortic valve opens End-systolic volume End-diastolic volume Stoke Volume Ejection Fraction = 85 = 59%

2 Systolic Heart Failure Filling Volume (ml) Pressure (mmHg) Contractility Pressure EDV ESV

3 Aortic Insufficiency Filling Stroke volume Volume (ml) Pressure (mmHg) Increase preload Increase in stroke volume Increase in ventricular pressure

4 Hypertension (Increase TPR) Filling Volume (ml) Pressure (mmHg) Increase after load Increase in ventricular pressure

5 Aortic Stenosis Filling Volume (ml) Pressure (mmHg) Increase after load Increase in ventricular pressure Decrease in stroke volume

6 Increased Contractility Filling Volume (ml) Pressure (mmHg) Decrease ESV Increase SV Slight decrease in EDV

7 Mitral Stenosis Filling Volume (ml) Pressure (mmHg) Decrease Contractility Decrease Presssure Increase EDV Increase ESV

8 Mitral Insufficiency Filling Volume (ml) Pressure (mmHg)
