Success in a Fontan pregnancy: how important is ventricular function?

Area of Science:

• Cardiology
• Congenital Heart Disease
• Maternal-Fetal Medicine

Background:

• The Fontan operation is a palliative surgery for single-ventricle physiology.
• Pregnancy in Fontan patients presents significant hemodynamic challenges.
• Outcomes for Fontan patients during pregnancy are historically variable.

Observation:

• This report details a case of pregnancy in a Fontan patient.
• The patient lacked pre-pregnancy risk factors typically associated with adverse outcomes.
• Despite the absence of high-risk features, a poor fetal outcome was observed.

Findings:

• The case demonstrates a particularly poor fetal outcome in a Fontan patient.
• Hemodynamic changes during pregnancy can negatively impact fetal well-being.
• Absence of pre-pregnancy risk factors does not guarantee a favorable pregnancy outcome.

Implications:

• This case underscores the complex risks of pregnancy for Fontan survivors.
• Further research is needed to understand and mitigate pregnancy-related risks in this population.
• Improved monitoring strategies may be necessary for Fontan patients during pregnancy.
