Background: Heart disease is a major cause of maternal mortality and morbidity during both the antepartum and postpartum periods. Heart disease occurs less frequently than 1% of the time during pregnancy. Cardiovascular disorders complicate about 1% of all pregnancies.A thorough evaluation of the patient throughout the entire pregnancy may result in the early detection of heart disease. So, the present study was conducted with an aim to assess the effect of heart disease in pregnancy and its outcome. Methods: This study was a cross-sectional study of the maternal-fetal outcomes of cardiac disease-related pregnancies over the last five years that were followed at tertiary care hospitals in North India. The study was carried out for three months after receiving institutional review board ethical approval. The study comprised pregnant patient files with pre-existing or newly diagnosed heart illness during pregnancy. Maternal age, parity,York Heart Association (NYHA) functional class, and maternofetal outcome were among the variables that were recorded. The collected data was entered in the MS excel sheet. The variables were presented as frequency and percentages.
