Mitral valve endocarditis due to Abiotrophia defectiva in a 14th week pregnant woman

Infective endocarditis during pregnancy carries a high mortality risk, both for the mother and for the foetus and requires a multidisciplinary team in the management of complicated cases. We report our experience with a 39-year old patient, affected by an acute active mitral endocarditis due to Abiotrophia defectiva at the 14th gestational week, strongly motivated to continue the pregnancy. Our patient successfully underwent mitral valve replacement with a normothermic high-flow cardiopulmonary bypass under continuous intraoperative foetal monitoring. Caesarean section occurred at the 38th gestational week. The delivery was uneventful and both the mother and child are doing well at the 16-month follow-up.
