# Noonan Syndrome and Heart Failure in a Postpartum Patient

## TL;DR

A postpartum woman with undiagnosed Noonan syndrome experienced heart failure and required specialized care, highlighting the challenges in managing such cases.

## Contribution

This case report presents a rare instance of undiagnosed Noonan syndrome complicated by heart failure in a postpartum patient.

## Key findings

- The patient exhibited characteristic facial features and echocardiographic findings consistent with Noonan syndrome.
- Biventricular failure and intracavitary thrombus were identified, requiring heart failure management and anticoagulation.
- The case underscores diagnostic and management challenges in Noonan syndrome-related cardiovascular complications.

## Abstract

A 29-year-old postpartum woman with no prior Noonan syndrome diagnosis was admitted for recurrent chest pain, dyspnea, and palpitations. She had two adverse pregnancy outcomes, including a neonatal death due to perinatal asphyxia. Physical examination revealed characteristic facial features, and echocardiography confirmed biventricular failure, hypertrophic cardiomyopathy, and a 2.5 cm intracavitary thrombus in the left ventricle. She was treated with heart failure management, anticoagulation, and diuretics before being referred to a specialized cardiology center. This case highlights the challenges in diagnosing and managing cardiovascular complications in suspected Noonan syndrome.
