Abstract
Heart disease during pregnancy encompasses a wide spectrum of disorders.Heart diseases during pregnancy is the leading indirect cause of maternal death all over the world. The marked hemodynamic changes associated with pregnancy explain the characteristic signs and symptoms that occur in the pregnant patient. Normal pregnancy is often associated with fatigue, dyspnea, and decreased exercise capacity. Pregnant women usually have peripheral edema and jugular venous distension. Most pregnant women have audible physiologic systolic murmurs, created by augmented blood flow. A physiologic third heart sound (S3), reflecting the volume overloaded state, can often be appreciated.The hemodynamic changes during the post-partum state are mainly due to relief of vena caval compression after delivery. The resultant increase in venous return augments cardiac output and causes a brisk diuresis. The hemodynamic changes return to the pre-pregnant baseline within 3 to 4 weeks following delivery.
