Noonan Syndrome and Heart Failure in a Postpartum Patient

Area of Science:

• Cardiology
• Genetics
• Maternal-Fetal Medicine

Background:

• Noonan syndrome is a genetic disorder with variable expressivity, often associated with cardiovascular abnormalities.
• Cardiovascular complications can manifest during pregnancy or postpartum, posing diagnostic challenges.

Observation:

• A 29-year-old postpartum woman presented with recurrent chest pain, dyspnea, and palpitations.
• Physical examination revealed facial features suggestive of Noonan syndrome.
• Echocardiography showed biventricular failure, hypertrophic cardiomyopathy, and a left ventricular thrombus.

Findings:

• The patient experienced adverse pregnancy outcomes, including a neonatal death.
• Cardiovascular findings were consistent with severe cardiac compromise.
• Diagnosis of Noonan syndrome was suspected based on clinical presentation and cardiac findings.

Implications:

• Early recognition of Noonan syndrome is crucial for managing cardiovascular risks in women of reproductive age.
• Prompt diagnosis and management of cardiac complications can improve outcomes.
• This case highlights the need for multidisciplinary care in suspected genetic syndromes with cardiac involvement.
