AB Normal  pregnancy  physiology  is  characterized  by  cardiovascular  adaptations  in  the  mother.  Cardiac  output  increases  markedly  as  a  result  of  both  augmented  stroke  volume  and  an  increase  in  the  resting  heart  rate,  and  the  maternal  blood  volume  expands  by  up  to  50%.  These  changes  may  not  be  tolerated  well  in  women  with  functional  or  structural  abnormalities  of  the  heart.  Thus,  although  only  a  small  number  of  pregnancies  are  complicated  by  cardiac  disease,  these  contribute  disproportionately  to  overall  rates  of  maternal  morbidity  and  mortality.  Most  cardiac  disease  in  women  of  childbearing  age  in  the  United  States  is  caused  by  congenital  heart  disease.  Ischemic  heart  disease,  however,  is  being  seen  more  commonly  in  pregnant  women  due  to  increasing  rates  of  comorbid  conditions,  such  as  diabetes  mellitus,  hypertension,  and  obesity.
