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) |
