Abstract:
Heart disease can affect anyone at any time, and pregnant women are not exceptions. Some type of cardiac pathologic disease can be seen in 1% to 2% of all pregnant women. Because of the high fetal mortality rate and the high relative rate of maternal mortality in surgery, medical management is the first line of treatment. Nevertheless, when medical treatment fails, cardiac surgery may be necessary. Here we present such a case of cardiac valvular disease complicated by pregnancy. Current decision-making, treatment, and trends are reviewed.

Heart Valves
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...
