Background: Although infective endocarditis (IE) in pregnancy is rare, maternal and foetal mortality rates are very high. We herein report the successful treatment of a case of IE with simultaneous emergent caesarean section and mitral valve replacement performed at 27 weeks of gestation.

Case Summary: A 29-year-old woman at 27 weeks of gestation was referred for congestive heart failure (HF) due to infective endocarditis (IE) with large mobile vegetations and overt disruption of the mitral valve. We held a multi-disciplinary conference and decided to perform mitral valve replacement immediately after caesarean section because of the high risk of embolism and sepsis, worsening and unstable haemodynamics, and sufficient foetal maturity for delivery. Although coronary artery embolization and asymptomatic multiple cerebral infarctions were observed, her post-operative course was uneventful. Ultimately, the patient was discharged 29 days after surgery. The neonate was treated in the NICU until the expected delivery date and was discharged home on Day 95 of life.

Discussion: Difficulties are associated with the selection of an operative plan and its timing for IE during pregnancy. Heart failure due to IE requires urgent surgery when medical treatment cannot stabilize the patient. However, cardiopulmonary bypass and medicine for pregnant women adversely affect the foetus. Therefore, the timing of surgery and delivery needs to be selected by a multi-disciplinary team and in consideration of the maternal condition and foetal maturity.

: Totally endoscopic techniques have become increasingly popular in cardiac surgery, with minimally invasive mitral valve repair emerging as an effective alternative to median sternotomy. This approach could be particularly advantageous for patients with Noonan syndrome, who often present with structural thoracic anomalies and other comorbidities like bleeding disorders. Endoscopic mitral valve surgery is rapidly establishing itself as the new standard of care for mitral valve operations, demonstrating both safety and efficacy.
