Cardiac Diseases in Pregnancy

< 5% of pregnancies.

Important cause of maternal mortality and morbidity.

The CVS adaptation to pregnancy, delivery and early pueperium can trigger acute cardiovascular de-compensation in women with high-risk lesions.

What happens is there are changes in the cardiovascular system during pregnancy, these changes (physiological) might affects those who already have cardiac disease or are at risk for cardiac disease.

Physiological Cardiovascular changes in pregnancy:

HR increase (peak at 32 weeks)

Cardiac Output Increase

Stroke Volume Increase

Left Ventricular Ejection Fraction Decrease

Blood Pressure Decrease initially around 32 weeks it will increase.

Peripheral Resistance Decrease

1- Rheumatic Heart Disease

Most commonly associated with mitral stenosis mitral regurgitation.

Could be aortic.

Mitral stenosis if valve area
