Pregnancy increases strain on the heart and blood vessels, raising blood volume and heart rate. Women with pre-existing heart conditions like arrhythmias or heart valve issues face heightened risks, including blood clots and potential complications for both mother and baby. It emphasized the need for thorough pre-pregnancy evaluation, ongoing monitoring, and carefully managed medications to ensure safety. Conditions such as congenital heart defects and severe heart failure may necessitate careful consideration or even advisement against pregnancy due to significant risks. Collaboration among cardiologists, maternal-fetal medicine specialists, and healthcare providers is crucial in developing tailored care plans for these women.
