Rapidly increasing maternal morbidity and death continue to be mostly attributed to cardiovascular disease. Whenever both the pregnant woman and the developing foetus are exposed to several possible difficulties, various physiological changes of gestation happen. Women who have pre-existing cardiac conditions, such as congenital abnormalities, angina pectoris, coronary artery disease and aortopathies, need to undergo multidisciplinary testing, counselling, and optimization before getting pregnant. They also need to be closely monitored and have their medication needs managed. Close monitoring is crucial for patients who developed cardiac conditions like congestive heart failure, preeclampsia, cardiomyopathy, coronary events, or arrhythmia while pregnant. The signs of a cardiac issue during pregnancy include- fatigue, chest pain, shortness of breath, fainting, difficulty breathing while sleeping.
