Pregnancy and Cardiopulmonary Bypass

  • Christina T. Mora


Pregnancy, with its attendant stress on the cardiovascular system, is a significant cause of morbidity and mortality in the patient with heart disease. Cardiovascular pathology is present in 0.4% to 4.1% of all gravidae, and accounts for 30% of all maternal deaths.1 Despite the overall decrease in deaths from cardiovascular disease among the general population in the last two decades, heart disease has become an increasingly likely cause of morbidity and mortality in the pregnant patient. But the prominence of heart disease is probably due to the decrease in other causes of maternal mortality. For example, Shearman2 compared the causes of maternal death in Australia during two periods, 1970 to 1972 and 1982 to 1984, and found that heart disease had become the most likely cause of death in the latter period (Table 24.1).
