BASICS
Description
- Mitral stenosis:
- Obstruction of diastolic blood flow into the left ventricle (LV)
- Mitral regurgitation:
- Inadequate closure of the leaflets allows retrograde blood flow into the left atrium (LA).
- Acute: Pressure overload in LA and pulmonary veins causing acute pulmonary edema
- Chronic: LV volume overload with dilatation and hypertrophy with LA enlargement
- Aortic stenosis:
- Obstruction of LV outflow with increased systolic gradient
- Progressive increase in LV systolic pressure and concentric hypertrophy
- Aortic regurgitation:
- Acute LV pressure and volume overload leading to left-heart failure and pulmonary edema
- Chronic volume overload with LV dilation and hypertrophy

Pregnancy Considerations
Pregnancy is associated with significant hemodynamic changes that can aggravate valvular heart disease and increase the risk of thromboembolic events.
