As a certified specialist in Maternal Fetal Medicine at the Rotunda, Professor Breathnach’s practice focuses on obstetric care, particularly on obstetric ultrasound. Her clinical areas of interest include high risk pregnancy, prenatal screening and diagnosis, and twin pregnancy. Her practice offers prenatal screening for chromosomal abnormality, prenatal diagnostic techniques including amniocentesis, chorionic villus sampling (CVS), non-invasive prenatal testing (NIPT) and advanced prenatal ultrasound services.

She is the lead obstetrician in the combined obstetric-endocrine service at the Rotunda. Together with a consultant specialist endocrinologist, dietician and specialist midwives, this team provides coordinated prenatal and postnatal care for women with diabetes in pregnancy. She completed her doctorate thesis on thyroid function in pregnancy.

Fionnuala also offers integrated prenatal care to women whose pregnancies have been complicated by a prenatal diagnosis of fetal congenital heart disease. This service is coordinated with our paediatric cardiology colleagues in Our Lady’s Children’s Hospital, Crumlin.
