Bacterial endocarditis in pregnancy causes maternal and fetal mortality rates of 22.1% and 14.7%, respectively. The mortality rates differ according to the involved valves, and the size of vegetation has a prognostic correlation. This report is of a pregnant woman with an unrepaired ventricular septal defect and pulmonary valve endocarditis with a vegetation size of 3.29 cm. She and her baby were treated successfully. An emergency surgical plan would be appropriate for pregnant women in the third trimester with a large vegetation in the right side of the heart, and dental disease should be treated aggressively with appropriate prophylactic antibiotics.
