mitral valve stenosis summary

-Impaired LV filling

-decreased preload -> decreased SV

- Diastolic murmur

-Increased LA and pul. vascular pressures

Aortic stenosis summary

-Large pressure gradient across aortic valve during systole

-Systolic ejection murmur-crescendo-decrescendo

-decreased SV

-ventricular hypertrophy (decreased compliance)

-increased filling pressure

-increased LA and pul. vascular pressures

Mitral regurgitation summary

-Tall v wave

-Systolic murmur

-Increased LA and pul. vascular pressures

-Increased LV filling pressure

-ventricular dilation

-Increased SV but decreased aortic flow

-no true isovolumetric phase

Aortic regurg summary

-increased aortic pulse pressure

-diastolic murmur- decrescendo

-increased SV but decreased net aortic flow

-Ventricular dilation

-No true isovolumetric phases

-Increased LV filling phase

-Increased LA and pul. vascular pressures

systolic heart failure leads to

ventricle dilation

diastolic heart failure leads to

ventricle hypertrophy

3rd heart sound

early diastole from rapid, turbulent filling of dilated ventricle

4th heart sound

when atrium contracts against a non-compliant ventricle (usually ventricular hypertrophy)
