Abstract

Background In women, pregnancy is a period of relatively drastic hemodynamic change in a short period of time. Most pregnant women adapt well to these gradual hemodynamic changes. However, in women with congenital heart disease or other structural heart disease, adaptation to theses sudden hemodynamic changes is difficult, and heart failure or arrhythmia can get aggravated. This study shares our experiences on the outcomes of pregnancy in patients with structural heart disease. Methods From January 2007 to December 2016, we reviewed the medical records of all pregnant women with structural heart disease who received obstetric care at the Sejong General Hospital. Results During the study period, 103 pregnancies were observed in 79 women with structural heart disease. Of the 103 pregnancies, 55 were primiparous and 48 were multiparous. Echocardiography performed before pregnancy revealed that 52 patients had moderate to severe valvular regurgitation and 38 patients had moderate to severe valvular stenosis; 22 patients had mechanical valves and 5 patients had pulmonary hypertension. Overall, there were 9 maternal cardiac events, 7 obstetric events and 19 neonatal events. Pulmonary embolic events occurred only in 1 case; 77 deliveries were made, and 26 pregnancies did not last. Among 77 deliveries, 55 patients delivered by cesarean section (C/S) (71.43%). C/S in 16 of 55 patients was performed due to the maternal hemodynamic risk. Conclusions Overall complications associated with pregnancy in women with structural heart disease were very high at 28.16%. However, it is hoped that maternal and neonatal outcomes will be improved through careful observation and preparedness for anticipated complications.
