Heart Disease encompasses a wide variety of conditions of the heart, some of the most common being hypertension, arrhythmia, congenital heart disease, and coronary artery disease. While cardiovascular disease (CVD) only affects approximately 1-4% of pregnancies, it can have a variety of effects on the mother--some being critical--and it is important for medical professionals and women who are looking to become pregnant to understand these effects [1].





  • Cardiovascular disease (CVD) affects approximately 1-4% pregnancies, and the rate of mortality due to CVD during pregnancy has been increasing over the years [2]

  • Maternal CVD appears to be increasing likely due to women becoming pregnant at a later age, and due to the prevalence cardiovascular risk factors such as obesity, diabetes and hypertension [2].

  • Congenital heart disease (CHD) is the most common   preexisting heart condition during pregnancy and  hypertension is the most common acquired condition [3].
